FRU Replacement Strategy  
Before Replacing Parts  
Ensure that all diskette fixes are installed prior to  
replacing any FRUs listed in this manual.  
Use the following strategy to prevent unnecessary FRU  
replacement and service expense:  
Ÿ
If you are instructed to replace a FRU and that  
does not correct the problem, reinstall the original  
FRU before you continue.  
Ÿ
Some computers have both a processor board and a  
system board. If you are instructed to replace either  
the processor board or the system board, and the first  
board that you replaced does not correct the problem,  
reinstall the original board, then replace the other  
(processor or system) board.  
Ÿ
If an adapter or device consists of more than one  
FRU, an error code may be caused by any of the  
FRUs. Before replacing the adapter or device,  
remove the FRUs, one by one, to see if the  
symptoms change. Replace only the FRU that  
changed the symptoms.  
Attention  
A customized setup configuration (other than default  
settings) may exist on the computer you are servicing.  
Running Automatic Configuration may alter those  
settings. Note the current configuration settings (using  
the View Configuration option) and verify that the  
settings are in place when service is complete.

The advanced diagnostic tests are intended to test only  
IBM products. Non-IBM products or modified options can  
give false errors and invalid responses.  
Hard Disk Drive Replacement Strategy:  
Always try to run a low-level format before replacing a hard  
disk drive.  
Attention  
The drive startup sequence in the computer you are  
servicing might have been changed. Be extremely  
careful during write operations such as copying,  
saving, or formatting. Data or programs can be  
overwritten if you select an incorrect drive.  
How to Use Error Messages  
Use the error codes displayed on the screen to diagnose  
failures. If more than one error code is displayed, begin  
the diagnosis with the first error code. The cause of the  
first error code can result in false error codes being  
displayed. If no error code is displayed, see if the error  
symptom is listed in the Symptom-to-FRU Index for the  
computer you are servicing.  
How to Read POST Error Messages  
POST error messages are displayed on the screen as  
three, four, five, or eight digits. The error messages that  
can be displayed as shorter POST messages are  
highlighted in this index. Some digits will represent  
different information for SCSI errors versus non-SCSI  
errors.  
The following example shows which digits display the  
shorter POST error messages and also defines the SCSI  
information in an eight-digit error message.

Device Code  
Slot Number (SCSI)  
Logical Unit Number (SCSI)  
ID (SCSI)  
All SCSI devices are set to a different SCSI ID.  
Duplicate SCSI ID settings can generate a false error  
message. Use the SCSI ID to determine whether the error  
message is coming from an internal or an external device.

Safety Notices (Multi-lingual  
Translations)  
In this manual, safety notices appear in English with a  
page number reference to the appropriate multi-lingual,  
translated safety notice found in this section.  
The following safety notices are provided in English,  
French, German, Italian, and Spanish languages.  
Safety Notice 1  
Before the computer is powered-on after FRU  
replacement, make sure all screws, springs, or other  
small parts are in place and are not left loose inside  
the computer. Verify this by shaking the computer  
and listening for rattling sounds. Metallic parts or  
metal flakes can cause electrical shorts.  
Avant de remettre l'ordinateur sous tension après  
remplacement d'une unité en clientèle, vérifiez que  
tous les ressorts, vis et autres pièces sont bien en  
place et bien fixées. Pour ce faire, secouez l'unité et  
assurez-vous qu'aucun bruit suspect ne se produit.  
Des pièces métalliques ou des copeaux de métal  
pourraient causer un court-circuit.  
Bevor nach einem FRU-Austausch der Computer  
wieder angeschlossen wird, muß sichergestellt  
werden, daß keine Schrauben, Federn oder andere  
Kleinteile fehlen oder im Gehäuse vergessen wurden.  
Der Computer muß geschüttelt und auf  
Klappergeräusche geprüft werden. Metallteile oder  
-splitter können Kurzschlüsse erzeugen.  
Prima di accendere l'elaboratore dopo che é stata  
effettuata la sostituzione di una FRU, accertarsi che  
tutte le viti, le molle e tutte le altri parti di piccole  
dimensioni siano nella corretta posizione e non siano  
sparse all'interno dell'elaboratore. Verificare ciò  
scuotendo l'elaboratore e prestando attenzione ad  
eventuali rumori; eventuali parti o pezzetti metallici  
possono provocare cortocircuiti pericolosi.  
Antes de encender el sistema despues de sustituir  
una FRU, compruebe que todos los tornillos, muelles  
y demás piezas pequeñas se encuentran en su sitio y  
no se encuentran sueltas dentro del sistema.  
Compruébelo agitando el sistema y escuchando los  
posibles ruidos que provocarían. Las piezas metálicas  
pueden causar cortocircuitos eléctricos.

Safety Information  
The following section contains the safety information that  
you need to be familiar with before servicing an IBM  
mobile computer.  
General Safety  
Follow these rules to ensure general safety:  
Ÿ
Ÿ
Observe good housekeeping in the area of the  
machines during and after maintenance.  
When lifting any heavy object:  
1. Ensure you can stand safely without slipping.  
2. Distribute the weight of the object equally  
between your feet.  
3. Use a slow lifting force. Never move suddenly  
or twist when you attempt to lift.  
4. Lift by standing or by pushing up with your leg  
muscles; this action removes the strain from the  
muscles in your back. Do not attempt to lift any  
objects that weigh more than 16 kg (35 lb) or  
objects that you think are too heavy for you.  
Do not perform any action that causes hazards to the  
customer, or that makes the equipment unsafe.  
Before you start the machine, ensure that other  
service representatives and the customer's personnel  
are not in a hazardous position.  
Ÿ
Ÿ
Ÿ
Place removed covers and other parts in a safe  
place, away from all personnel, while you are  
servicing the machine.  
Ÿ
Ÿ
Keep your tool case away from walk areas so that  
other people will not trip over it.  
Do not wear loose clothing that can be trapped in the  
moving parts of a machine. Ensure that your sleeves  
are fastened or rolled up above your elbows. If your  
hair is long, fasten it.  
Ÿ
Ÿ
Insert the ends of your necktie or scarf inside clothing  
or fasten it with a nonconductive clip, approximately 8  
centimeters (3 inches) from the end.  
Do not wear jewelry, chains, metal-frame eyeglasses,  
or metal fasteners for your clothing.  
Attention: Metal objects are good electrical  
conductors.  
Ÿ
Wear safety glasses when you are: hammering,  
drilling soldering, cutting wire, attaching springs, using  
solvents, or working in any other conditions that might  
be hazardous to your eyes.  
Ÿ
Ÿ
After service, reinstall all safety shields, guards,  
labels, and ground wires. Replace any safety device  
that is worn or defective.  
Reinstall all covers correctly before returning the  
machine to the customer.

Electrical Safety  
Observe the following rules when working on electrical  
equipment.  
Important  
Use only approved tools and test equipment. Some  
hand tools have handles covered with a soft material  
that does not insulate you when working with live  
electrical currents.  
Many customers have, near their equipment, rubber  
floor mats that contain small conductive fibers to  
decrease electrostatic discharges. Do not use this  
type of mat to protect yourself from electrical shock.  
Ÿ
Find the room emergency power-off (EPO) switch,  
disconnecting switch, or electrical outlet. If an  
electrical accident occurs, you can then operate the  
switch or unplug the power cord quickly.  
Ÿ
Ÿ
Do not work alone under hazardous conditions or  
near equipment that has hazardous voltages.  
Disconnect all power before:  
–
–
–
Performing a mechanical inspection  
Working near power supplies  
Removing or installing main units  
Ÿ
Ÿ
Before you start to work on the machine, unplug the  
power cord. If you cannot unplug it, ask the customer  
to power-off the wall box that supplies power to the  
machine and to lock the wall box in the off position.  
If you need to work on a machine that has exposed  
electrical circuits, observe the following precautions:  
–
Ensure that another person, familiar with the  
power-off controls, is near you.  
Attention: Another person must be there to  
switch off the power, if necessary.  
–
Use only one hand when working with  
powered-on electrical equipment; keep the other  
hand in your pocket or behind your back.  
Attention: There must be a complete circuit to  
cause electrical shock. By observing the above  
rule, you may prevent a current from passing  
through your body.  
–
–
When using testers, set the controls correctly  
and use the approved probe leads and  
accessories for that tester.  
Stand on suitable rubber mats (obtained locally,  
if necessary) to insulate you from grounds such  
as metal floor strips and machine frames.  
Observe the special safety precautions when you  
work with very high voltages; these instructions are in  
the safety sections of maintenance information. Use  
extreme care when measuring high voltages.  
16 IBM Mobile Systems - ThinkPad HMM Volume 3

Ÿ
Regularly inspect and maintain your electrical hand  
tools for safe operational condition.  
Ÿ
Ÿ
Do not use worn or broken tools and testers.  
Never assume that power has been disconnected  
from a circuit. First, check that it has been  
powered-off.  
Ÿ
Ÿ
Ÿ
Always look carefully for possible hazards in your  
work area. Examples of these hazards are moist  
floors, nongrounded power extension cables, power  
surges, and missing safety grounds.  
Do not touch live electrical circuits with the reflective  
surface of a plastic dental mirror. The surface is  
conductive; such touching can cause personal injury  
and machine damage.  
Do not service the following parts with the power on  
when they are removed from their normal operating  
places in a machine:  
–
–
–
–
Power supply units  
Pumps  
Blowers and fans  
Motor generators  
and similar units. (This practice ensures correct  
grounding of the units.)  
Ÿ
If an electrical accident occurs:  
–
Use caution; do not become a victim  
yourself.  
–
–
Switch off power.  
Send another person to get medical aid.  
Safety Inspection Guide  
The intent of this inspection guide is to assist you in  
identifying potentially unsafe conditions on these products.  
Each machine, as it was designed and built, had required  
safety items installed to protect users and service  
personnel from injury. This guide addresses only those  
items. However, good judgment should be used to identify  
potential safety hazards due to attachment of non-IBM  
features or options not covered by this inspection guide.  
If any unsafe conditions are present, you must determine  
how serious the apparent hazard could be and whether  
you can continue without first correcting the problem.  
Consider these conditions and the safety hazards they  
present:  
Ÿ
Electrical hazards, especially primary power (primary  
voltage on the frame can cause serious or fatal  
electrical shock).  
Ÿ
Ÿ
Explosive hazards, such as a damaged CRT face or  
bulging capacitor  
Mechanical hazards, such as loose or missing  
hardware  
Introduction 17  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The guide consists of a series of steps presented in a  
checklist. Begin the checks with the power off, and the  
power cord disconnected.  
Checklist:  
1. Check exterior covers for damage (loose, broken, or  
sharp edges).  
2. Power-off the computer. Disconnect the power cord.  
3. Check the power cord for:  
a. A third-wire ground connector in good condition.  
Use a meter to measure third-wire ground  
continuity for 0.1 ohm or less between the  
external ground pin and frame ground.  
b. The power cord should be the appropriate type  
as specified in the parts listings.  
c. Insulation must not be frayed or worn.  
4. Remove the cover.  
5. Check for any obvious non-IBM alterations. Use  
good judgment as to the safety of any non-IBM  
alterations.  
6. Check inside the unit for any obvious unsafe  
conditions, such as metal filings, contamination, water  
or other liquids, or signs of fire or smoke damage.  
7. Check for worn, frayed, or pinched cables.  
8. Check that the power-supply cover fasteners (screws  
or rivets) have not been removed or tampered with.

Handling Electrostatic  
Discharge-Sensitive Devices  
Any computer part containing transistors or integrated  
circuits (ICs) should be considered sensitive to electrostatic  
discharge (ESD). ESD damage can occur when there is a  
difference in charge between objects. Protect against ESD  
damage by equalizing the charge so that the machine, the  
part, the work mat, and the person handling the part are all  
at the same charge.  
Notes  
1. Use product-specific ESD procedures when they  
exceed the requirements noted here.  
2. Make sure that the ESD protective devices you  
use have been certified (ISO 9000) as fully  
effective.  
When handling ESD-sensitive parts:  
Ÿ
Keep the parts in protective packages until they are  
inserted into the product.  
Ÿ
Ÿ
Avoid contact with other people.  
Wear a grounded wrist strap against your skin to  
eliminate static on your body.  
Ÿ
Ÿ
Ÿ
Prevent the part from touching your clothing. Most  
clothing is insulative and retains a charge even when  
you are wearing a wrist strap.  
Use the black side of a grounded work mat to provide  
a static-free work surface. The mat is especially  
useful when handling ESD-sensitive devices.  
Select a grounding system, such as those listed  
below, to provide protection that meets the specific  
service requirement.  
Note  
The use of a grounding system is desirable but  
not required to protect against ESD damage.  
–
–
Attach the ESD ground clip to any frame ground,  
ground braid, or green-wire ground.  
Use an ESD common ground or reference point  
when working on a double-insulated or  
battery-operated system. You can use coax or  
connector-outside shells on these systems.  
Use the round ground-prong of the AC plug on  
AC-operated computers.  
–
Grounding Requirements  
Electrical grounding of the computer is required for  
operator safety and correct system function. Proper  
grounding of the electrical outlet can be verified by a  
certified electrician.

Read This First  
This hardware maintenance manual contains information  
for the IBM ThinkPad 365 computer.  
Ÿ
Be extremely careful during write operations such  
as copying, saving, or formatting. Drives in the  
computer that you are servicing might have been  
rearranged or the drive startup sequence might have  
been altered. If you select an incorrect drive, data or  
programs can be written over.  
Ÿ
Ÿ
Use only the correct FRUs. When you replace a  
FRU, make sure the model of the machine and FRU  
part number are correct by referring to the parts  
listing.  
FRUs should not be replaced because of a single,  
un-reproducible failure. Single failures can occur  
from a variety of reasons that have nothing to do with  
a hardware defect such as electrostatic discharge or  
software errors. FRU replacement should only be  
considered when a recurring problem exists.  
The servicer must include the following in the parts  
exchange form or part return form that is attached to the  
returned FRU.  
1. Name and phone number of servicer.  
2. Date of service.  
3. Date when part failed.  
4. Date of purchase.  
5. Failure symptoms, error codes appearing on  
display, and beep symptoms.  
6. Procedure index and page number in which  
failing FRU was detected.  
7. Failing FRU name and part number.  
8. Machine type, model number, and serial number.  
9. Customer's name and address.

How to Use Error Messages: Use the error  
codes or messages displayed on the screen to diagnose  
failures. If more than one error code is displayed, begin  
the diagnosis with the first error code. The cause of the  
first error code can result in false error codes being  
displayed. If no error code is displayed, see if the error  
symptom is listed in the “Symptom-to-FRU Index” on  
page 41.  
How to Diagnose Multiple FRUs: When the  
adapter or device has more than one FRU, the error code  
could be caused by either FRU. Before replacing  
multiple-FRUs, try removing or exchanging each FRU, one  
by one in the designated sequence, to see if the symptoms  
change.  
Passwords: The Passwords are security features that  
are used to protect the system and the hard disk data from  
unauthorized access. There are two types of passwords:  
Ÿ
Ÿ
User Password  
Supervisor Password  
How to Disable the Passwords

over voltage protection circuit to be fully discharged  
and initialized.  
3. Plug the AC Adapter cable into the ac power outlet.  
36 IBM Mobile Systems - ThinkPad HMM Volume 3  
Download from Www.Somanuals.com. All Manuals Search And Download.  
4. Measure the output voltage of the AC Adapter.  
5. If the voltage is still not correct, replace the AC  
Adapter.  
Note: An audible noise from the AC Adapter does not  
always indicate a defective adapter.  
Checking Operational Charging: To check  
operational charging, use a discharged battery pack or a  
battery pack that shows an amber battery status indicator  
when it is installed in the computer.  
Perform operational charging. If the battery status  
indicator turns orange and the battery charging indicator  
turns green within two minutes, replace the AC Adapter.  
Checking the Battery Pack: Battery charging will  
not start until the Fuel-Gauge shows that less than 90% of  
the total power remains; with this condition the battery  
pack will charge to 100% of its capacity. This protects the  
battery pack from being over-charged or having a  
shortened life.  
Before you perform the following procedure, be sure you  
have the correct battery pack for this model.  
1. Power-off the computer.  
2. Remove the battery pack and measure the voltage  
between battery terminals 2 (+) and 6 (−). See the  
following figure.  
3. If the voltage is less than +7.2 V dc, the battery pack  
has been discharged or is defective. Recharge the  
battery. If the recharging does not work, go to Step 5  
on page 38 to check the charging circuit.  
If the voltage is still less than +7.2 V dc after the  
recharging, replace the battery.  
4. If the voltage is more than +7.2 V dc, measure the  
resistance between battery terminals 4 and 6. The  
resistance must be 4K ohms to 30K ohms.  
If the resistance is not correct, replace the battery  
pack.  
If the resistance is correct, replace the DC/DC card.

5. To check the charging circuit, do the following. Plug  
in the AC Adapter with the battery pack removed,  
then power-on the computer.  
6. Measure the charging voltage between DC/DC  
terminals 2 (+) and 6 (−).  
7. If the voltage is less then +9.0 V dc, replace the  
DC/DC card. If the voltage is more than +9.0 V dc,  
the charging circuit is working correctly, replace the  
battery pack.

down the central processing unit and the system uses less  
power. Enable the doze mode in the setup program.  
Exiting the doze mode is instantaneous by pressing any  
keyboard key.  
Safe Suspend: Saves the computer state, then  
enters the suspend mode.  
Port Replicator Power Overload: If power shut  
downs occur intermittently when using a port replicator,  
suspect an over-current problem. Some devices use more  
power; if the maximum usage of each device occurs  
simultaneously, the total current will exceed the limit,  
thereby causing a power shut down. Isolate this problem  
by removing one of the devices, and use the computer  
under the same condition to see whether a power shut  
down occurs. Do this procedure for all devices, then  
determine the cause.

Symptom-to-FRU Index  
The Symptom-to-FRU Index lists error symptoms and  
possible causes. The most likely cause is listed first.  
Always begin with “General Checkout” on page 30. This  
index can also be used to help you decide which FRUs to  
have available when servicing a computer.  
If you are unable to correct the problem using this index,  
go to “Undetermined Problems” on page 49.  
Notes

If you have both an error message and an  
incorrect audio response, diagnose the error  
message first.  
Check all power supply voltages before you  
replace the system board. (See “Power Systems  
Checkout” on page 35.)

Intermittent Problems  
Intermittent system hang problems can be caused by a  
variety of reasons that have nothing to do with a hardware  
defect such as: cosmic radiation, electrostatic discharge, or  
software errors. FRU replacement should only be  
considered when a recurring problems exits.  
When analyzing the intermittent problem, do the following:  
1. Run the diagnostic test for the system board in loop  
mode at least 10 times.  
2. If any error is detected, replace the FRU indicated.  
Rerun the test to verify that no more errors exist.

Undetermined Problems  
You are here because the diagnostic tests did not identify  
which adapter or device failed, installed devices are  
incorrect, a short circuit is suspected, or the system is  
inoperative. Follow the procedures below to isolate the  
failing FRU (do not isolate non-defective FRUs).  
Verify that all attached devices are supported by the  
computers.  
Verify that the power supply being used at the time of the  
failure is operating correctly. (See “Power Systems  
Checkout” on page 35.)  
1. Power-off the computer.  
2. Check the cables, wires, and connectors for short  
circuits and open circuits. Visually check them for  
damage. If any problems are found, replace the  
FRU.  
3. Remove or disconnect all of the following devices.  
a. Non-IBM devices  
b. Devices attached to external connectors  
c. Printer, mouse, and other external devices  
d. Battery pack  
e. Hard disk drive  
f. Diskette drive or the device attached to the  
diskette drive connector  
g. DIMM card  
h. CD-ROM  
i. Sound card  
j. Port replicator  
k. Keyboard  
l. Keyboard card  
Note: Remember that removing the hard disk  
drive, or any adapter or device, might cause  
configuration errors. Ignore error code 174.  
4. Power-on the computer.  
5. Determine if the problem has changed.  
6. If the problem does not occur again, reconnect the  
removed devices one at a time until you find the  
failing FRU.  
7. If the problem remains, replace the following FRUs  
one at a time. Do not replace a non-defective FRU.

How to Run Diagnostics  
The QAPlus/PRO diagnostic program, developed by  
DiagSoft for IBM, is the primary method of testing the  
computer. It is unique to the ThinkPad 365 and will not  
run on other models. You can use it to test the IBM  
components of the system and some external devices.  
The amount of time required to test all components  
depends on the number of components. The more  
optional adapters and devices you have attached to your  
system, the longer the testing takes.  
Important  
Before loading the diagnostics program:  
1. Go to a DOS full screen.  
2. Press Ctrl+Alt+F11 to go to the setup screen.  
3. Verify all peripherals devices are enabled.  
4. Page Down to the second page and verify all  
peripherals are enabled.  
The diagnostics program is intended to test only IBM  
products. Non-IBM products, prototype cards, or modified  
options can give false errors and invalid system responses.

Read This First  
Before you go to the checkout guide, be sure to read this  
section.  
Important Notes  
Ÿ
Ÿ
Ÿ
Only certified trained personnel should  
service the computer.  
Read FRU service procedures before replacing  
any FRUs.  
Be extremely careful during write operations  
such as copying, saving, or formatting. Drives  
in the computer that you are servicing might have  
been rearranged or the drive startup sequence  
might have been altered. If you select an  
incorrect drive, data or programs can be written  
over.  
Ÿ
Ÿ
Replace FRUs only for the correct model.  
When you replace the FRU, make sure the  
model of the machine and FRU part number are  
correct by referring to the parts list.  
FRUs should not be replaced because of a  
single, un-reproducible failure. Single failures  
can occur from a variety of reasons that have  
nothing to do with a hardware defect such as:  
cosmic radiation, electrostatic discharge, or  
software errors. FRU replacement should only  
be considered when a recurring problem exists.  
If this is suspected, clear the error log and run  
the test again. Do not replace any FRUs if log  
errors do not reappear.  
Ÿ
Be careful not to replace a non-defective FRU.  
How to Use Error Messages: Use the error  
codes displayed on the screen to diagnose failures. If  
more than one error code is displayed, begin the diagnosis  
with the first error code. The cause of the first error code  
can result in false error codes being displayed. If no error  
code is displayed, see if the error symptom is listed in the  
“Symptom-to-FRU Index” on page 106.  
Port Replicator Problems: If you suspect a  
problem with the Port Replicator, see “Port Replicator  
Checkout” in the “Common Devices Checkout” section.  
How to Diagnose Multiple FRUs: When the  
adapter or device has more than one FRU, the error code  
could be caused by either FRU. Before replacing multiple  
FRUs, try removing or exchanging each FRU, one by one  
in the designated sequence, to see if the symptoms  
change.

What to Do First: The servicer must include the  
following information on the parts exchange form or parts  
return form that is attached to the returned FRU:  
1. Name and phone number of servicer.  
2. Date of service.  
3. Date when part failed.  
4. Date of purchase.  
5. Failure symptoms, error codes appearing on  
display, and beep symptoms.  
6. Procedure index and page number in which  
failing FRU was detected.  
7. Failing FRU name and part number.  
8. Machine type, model number, and serial number.  
9. Customer's name and address.  
Before checking problems with the computer, determine  
whether or not the damage is covered by the warranty by  
referring to the following:  
Warranty Note  
During the warranty period, the customer may be  
responsible for repair costs if the computer damage  
was caused by misuse, accident, modification,  
unsuitable physical or operating environment, or  
improper maintenance by the customer. The following  
list provides some common items that are not covered  
under warranty and some symptoms that may indicate  
the system was subjected to stresses beyond normal  
use.  
Ÿ
LCD panel cracked by excessive force or being  
dropped.  
Ÿ
Ÿ
Scratched (cosmetic) parts.  
Cracked or broken plastic parts, broken latches,  
broken pins, or broken connectors caused by  
excessive force.  
Ÿ
Ÿ
Damage caused by liquid spilled into the system.  
Damage caused by improperly inserting a  
PCMCIA card or installation of an incompatible  
card.  
Ÿ
Ÿ
Damage caused by foreign material in the  
diskette drive slot.  
Diskette drive damage caused by pressing the  
diskette drive cover or inserting diskettes with  
multiple labels.  
Ÿ
Ÿ
Damaged or bent diskette eject button.  
CD-ROM drive damage caused by excessive  
force, shock, or from being dropped.  
Fuses blown by attaching a non-supported  
device.  
Ÿ
Ÿ
Forgotten computer or hard disk password  
(making computer or hard disk unusable).

If the following symptoms are present, they may  
indicate damage caused by non-warranted  
activity:  
Ÿ
Ÿ
Ÿ
Missing parts may be a symptom of unauthorized  
service or modification.  
HDD spindles can become noisy if subjected to  
excessive force or if the HDD is dropped.  
I9990303 errors can be caused by exposure to  
strong magnetic fields.  
How to Disable the Power-On Password:  
Important  
This information is not available in this online HMM  
format. See your IBM Servicer or IBM Authorized  
Dealer for this procedure.  
Supervisor and Hard Disk Passwords: The  
Supervisor Password and the Hard Disk Password (HDP)  
are security features that are used to protect the system  
and the hard disk data from unauthorized access. No  
overriding capability is provided. If only a hard disk  
password is set, obtaining permission from the password  
owner to unlock the password is a prerequisite for running  
diagnostic tests and performing service. If both supervisor  
password and hard disk password are set, you can enter  
Easy-Setup by pressing the Enter key or power-on  
password at the supervisor password prompt. In this case,  
the Password, Start up, and Initialize icons cannot be  
selected.  
See “Password Combinations (POP, HDP, PAP)” on  
page 124 for more information about passwords.

Checkout Guide  
Use the following procedure as a guide for computer  
problems.  
Note  
The diagnostic tests are intended to test only IBM  
products. Non-IBM products, prototype cards, or  
modified options can give false errors and invalid  
system responses.  
1. Obtain the failing symptoms in as much detail as  
possible.  
2. Verify the symptoms by attempting to recreate the  
failure by running the diagnostic test or by repeating  
the same operation.  
Note  
To run the diagnostics, refer to “How to Run the  
Diagnostics” on page 120.  
3. Use the following table with the verified symptom to

3. Select Update system programs from the menu.  
System Board and CPU Card Checkout  
The processing functions are performed by both the  
system board and the CPU card. Processor problems can  
be caused by either FRU. However, the CPU card  
generally has a lower probability of failure. When a  
numeric code calls the system board or the CPU card as a  
FRU, or the CPU card is called by a diagnostic test by  
showing FRU code 11, use the following procedure to  
isolate the problem:  
1. Run the system board test to verify the symptom.  
This test verifies both the system board and the CPU  
card. If no error is detected, return to “Checkout  
Guide” on page 96.  
2. If FRU code 10 appears, replace the system board  
but do not replace the CPU card. Transfer the CPU  
card from the old system board to the new system  
board.  
3. If FRU code 11 appears, reseat the CPU card.  
4. Rerun the test to verify the fix.  
5. If FRU code 11 remains, replace the CPU card.  
If above procedure does not correct the problem, go to  
“Undetermined Problems” on page 116.  
Keyboard/Auxiliary Input Device  
Checkout  
Remove the external keyboard if the internal keyboard is to  
be tested.  
If the internal keyboard does not work or an unexpected  
character appears, make sure that the three flexible cables  
extending from the keyboard are correctly seated in the  
connectors on the keyboard card.  
If the keyboard cable connections are correct, check the  
keyboard card.

TrackPoint III Checkout  
If the TrackPoint III will not work, check the configuration in  
the ThinkPad Features program. If the configuration of the  
TrackPoint III is disabled, select Enable to enable it.  
If this does not correct the TrackPoint III problem, continue  
with the following steps.  
The TrackPoint III does automatic compensations to adjust  
the pointer sensor. During this process, the pointer moves  
on the screen automatically for a short time. This  
self-acting pointer movement can occur when a slight,  
steady pressure is applied to the TrackPoint III pointer  
while the computer is powered on or while the system is  
running, or when re-adjustment is required because the  
temperature has exceeded its normal temperature range.  
This symptom does not indicate a hardware problem. No  
service actions are necessary if the pointer movement  
stops in a short period of time.  
If a click button problem or pointing stick problem occurs,  
do the following:  
1. Go to the Easy-Setup screen.  
2. Select an item with the pointing stick.  
3. Press either the left or right click button.  
4. Verify that both buttons work correctly.  
If either the pointing stick or the click button do not work,  
do the following actions one at a time to correct the  
problem. Do not replace a non-defective FRU.

2. Go to the Easy-Setup screen.  
3. Select an item with the joystick.  
4. Press any button of the joystick.  
5. Verify that all buttons work correctly.  
If either the joystick or a button does not work, replace the  
Port Replicator. If the problem still remains, replace the  
system board.  
Diskette Drive Test  
Do the following to isolate the problem to a controller,  
drive, or diskette. A scratch, write enabled, non-defective  
2HD diskette is required.  
FDD-1 represents the built-in diskette drive for 365X.  
FDD-2 represents a diskette drive in the Port Replicator or

a diskette drive attached through the external diskette drive  
connector.  
Warning: Make sure that the diskette does not have  
more than one label attached to it. Multiple labels can  
cause damage to the drive or can cause the drive to fail.  
Do the following to select the test device:  
1. Select the advanced diagnostics mode and select  
Tool; then select the FDD-1 or FDD-2 icon and press  
the spacebar. A √ mark appears next to the selected  
icon. Insert a blank diskette when instructed.  
2. Run the diskette drive test.  
3. If the controller test detects an error, FRU code 10  
appears. Replace the system board.  
4. If the controller test runs without errors, the drive  
read/write tests start automatically.  
5. If the drive test detects an error, FRU code 50 for  
FDD-1 or 51 for FDD-2 appears. If the diskette itself  
is known to be good, replace the drive.  
Status Indicators Checkout  
If a status indicator LED problem occurs, do the following:  
1. Power off the computer.  
2. Power on the computer.  
3. All the LEDs in the status indicator panel turn on for a  
moment soon after the computer is powered on.  
Verify that all indicators turn on correctly.  
If some of the indicators do not turn on, replace the LED  
indicator card.  
If the problem still remains, replace the keyboard card.  
Power Systems Checkout  
To verify the symptom of the problem, power on the  
computer using each of the power sources as follows:  
1. Remove the battery pack, diskette drive, and hard  
disk drive.  
2. Connect the AC Adapter and check that power is  
supplied.  
3. Install the diskette drive or hard disk drive one at a  
time, and check that power is supplied from each  
power source.  
4. Disconnect the AC Adapter, remove the hard disk and

Checking the AC Adapter: You are here  
because the computer fails only when the AC Adapter is  
used.  
Ÿ
If the power problem occurs only when a Port  
Replicator is used, replace the replicator.  
If the power-on indicator does not turn on, check the  
power cord of the AC Adapter for correct continuity  
and installation.  
Ÿ
Ÿ
If the operational charge does not work, go to  
“Checking Operational Charging” on page 102.  
Note  
There are two types of adapters. The procedure for  
checking both types is the same.  
1. Unplug the AC Adapter cable from the computer and  
measure the output voltage at the plug of the AC  
Adapter cable. See the following figure:

If the voltage is correct, replace the system board.  
If the problem is not corrected, go to “Undetermined  
Problems” on page 116.  
Ÿ
If the voltage is not correct, go to the next step.  
2. Unplug the AC Adapter cable from the ac power  
outlet and wait five minutes or longer to allow the  
over-voltage protection circuit to be fully discharged  
and initialized.  
3. Plug the AC Adapter cable into the ac power outlet.  
4. Measure the output voltage of the AC Adapter.  
5. If the voltage is still not correct, replace the AC  
Adapter.  
Note  
An audible noise from the AC Adapter does not  
always indicate a defective adapter.

Checking Operational Charging: To check  
operational charging, use a discharged battery pack or a  
battery pack that has less than 50% of the total power  
remaining when installed in the computer.  
Perform operational charging. If the battery status  
indicator does not turn on, remove the battery pack and  
leave it to return to room temperature. Reinstall the  
battery pack. If the charge indicator still does not turn on,  
replace the battery pack.  
Checking the Battery Pack: Battery charging will  
not start until the Fuel-Gauge shows that less than 95% of  
the total power remains; with this condition the battery  
pack will charge to 100% of its capacity. This protects the  
battery pack from being overcharged or having a  
shortened life.  
Do the following:  
1. Power off the computer.  
2. Remove the battery pack and measure the voltage  
between battery terminals 2 (+) and 6 (−). See the  
following figure:

3. If the voltage is less than +9.6 V dc, the battery pack  
has been discharged. Recharge the battery pack.  
If the voltage is still less than +9.6 V dc after  
recharging, replace the battery.  
Note  
If the voltage of the battery pack is 0 V, it is not  
defective.  
4. If the voltage is more than +9.6 V dc, measure the  
resistance between battery terminals 5 and 6. The  
resistance must be 4 K to 30 K ohm.  
If the resistance is not correct, replace the battery  
pack. If the resistance is correct, replace the system  
board.  
Checking the Backup Battery  
1. Power off the computer and unplug the AC Adapter  
from the computer.  
2. Open the keyboard and remove the battery pack.  
3. Lift the right-hand section of the black insulator sheet.  
4. Locate the backup battery on the system board,  
shown at .1/.

LCD–Related Symptoms  
Important  
The TFT LCD on some models of this computer  
contains over 1,440,000 thin-film transistors (TFTs). A  
small number of missing, discolored, or lighted dots

Note  
If you cannot find a symptom or error in this list and  
the problem remains, see “Undetermined Problems”  
on page 116.  
Intermittent Problems  
Intermittent system hang problems can be caused by a  
variety of reasons that have nothing to do with a hardware  
defect, such as: cosmic radiation, electrostatic discharge,  
or software errors. FRU replacement should only be  
considered when a recurring problem exists.  
When analyzing the intermittent problem, do the following:  
ThinkPad 365X, 365XD (2625) 115  
Download from Www.Somanuals.com. All Manuals Search And Download.  
1. Run the advanced diagnostic test for the system  
board in loop mode at least 10 times.  
2. If no error is detected, do not replace any FRUs.  
3. If any error is detected, replace the FRU shown by  
the FRU code. Rerun the test to verify that no more  
errors exist.  
Undetermined Problems  
You are here because the diagnostic tests did not identify  
which adapter or device failed, installed devices are  
incorrect, a short circuit is suspected, or the system is  
inoperative. Follow the procedures below to isolate the  
failing FRU (do not isolate non-defective FRUs).  
Verify that all attached devices are supported by the  
computer.  
Verify that the power supply being used at the time of the  
failure is operating correctly. (See “Power Systems  
Checkout” on page 100.)  
1. Power off the computer.  
2. Check the cables, wires, and connectors for short  
circuits and open circuits. Visually check them for  
damage. If any problems are found, replace the  
FRU.  
3. Remove or disconnect all of the following devices.  
a. Non-IBM devices  
b. Devices attached to the expansion bus  
connector  
c. Printer, mouse, and other external devices  
d. Battery pack  
e. Hard disk drive  
f. Internal diskette drive or CD-ROM drive  
g. DIMM  
h. PC Cards  
4. Power on the computer.  
5. Determine if the problem has changed.  
6. If the problem does not occur again, reconnect the  
removed devices one at a time until you find the  
failing FRU.  
7. If the problem still remains, remove the backup  
battery and wait for 3 minutes; then replace the  
backup battery and set current date and time.  
8. Determine if the problem has changed.  
9. If the problem remains, replace the following FRUs  
one at a time. Do not replace a non-defective FRU.

Checking the Installed Devices List  
If a device is installed but the icon appears in a gray shade  
rather than a dark shade on the basic diagnostics screen,  
the device is defective. Reseat the device connectors. If  
the symptom remains, replace the device or the system  
board. If needed, adjust the contrast control to clearly  
distinguish the shade of the icon.  
If a device that is not installed appears in a dark shade (for  
example, FDD-2 appears in a dark shade when no second  
FDD is installed), do the following:  
1. Replace the first device in the configuration, such as  
the FDD-1.  
2. If the problem remains, replace the system board.  
The PCMCIA, Parallel, and Serial icons are always  
displayed in a dark shade because the icons represent  
subsystems of the system board and not the actual  
attachment of the devices.

The FDD-1 icon represents the first drive in the system  
configuration. Similarly, the FDD-2 icon represents the  
second drive, attached to the external diskette drive  
connector or through a Port Replicator.  
Password Combinations (POP, HDP,  
PAP)  
When the power-on password (POP), hard disk password  
(HDP), and supervisor password (PAP) are used, the  
following situations may occur:  
Ÿ
When the POP is the same as the HDP  
The POP prompt appears, but the HDP prompt does  
not appear.  
Ÿ
Ÿ
When the POP is not the same as the HDP  
The POP and HDP prompts both appear.  
When the PAP and HDP are enabled  
When a PAP is used, the HDP is enabled  
automatically, but no HDP prompt appears. The HDP  
is set to the same password as the PAP.  
How to Run a Low-Level Format

Warning: Make sure the drive address to be formatted is  
correct. This procedure will erase all information on the  
disk.  
1. Power off the computer.  
2. Insert the ThinkPad 750Ce hardware maintenance  
diskette into diskette drive A and power on the  
computer.  
Note  
You can use this maintenance diskette for the  
ThinkPad 365X and 365XD computers.  
3. Select Format the hard disk from the main menu.  
4. Select the drive from the menu.  
5. Follow the instructions on the screen.  
PC Test Card LED  
The green LED on the PC test card turns on when the  
PCMCIA test is running. If the LED does not turn on,  
check that the card is installed correctly by reseating the  
card. If it still does not turn on after it is reseated, try  
using another slot for the test. If the LED still does not  
turn on and the test fails, replace the FRU shown by the  
diagnostic error code.

properly. If these connectors are not connected,  
you cannot power on the computer.  
Do not apply any extra force to the shaded

Notes  
1. The system unit serial number must be restored  
when the system board is replaced. To restore  
the system unit serial number, select the option  
“Set system identification” on the maintenance  
diskette. The EEPROM on the system board  
contains the vital product data (VPD); that is, the  
system unit serial number, system board system  
number, and other computer-unique data.  
2. Do not power off the computer when restoring  
the VPD. The system unit serial number label is  
attached to the base cover.  
3. Before removing and replacing the system board,  
make sure that the PCMCIA cards are removed  
and the eject levers are not sticking out.  
4. Do not pull the PCMCIA slot assembly while  
removing the system board.  
5. When handling the PCMCIA slot assembly, be  
careful not to disassemble any part of it. The slot  
assembly is not solidly fixed when it is removed  
from the system board or the FRU.

section.  
Important Notes  
Ÿ
Ÿ
Ÿ
Only certified trained personnel should  
service the computer.  
Read FRU service procedures before replacing  
any FRUs.  
Be extremely careful during write operations  
such as copying, saving, or formatting.  
Drives in the computer that you are servicing  
might have been rearranged or the drive startup  
sequence might have been altered. If you select  
an incorrect drive, data or programs can be  
written over.  
Ÿ
Ÿ
Replace FRUs only for the correct model.  
When you replace the FRU, make sure the  
model of the machine and FRU part number are  
correct by referring to the part list.  
FRUs should not be replaced because of a  
single, unreproducible failure. Single failures  
can occur from a variety of reasons that have  
nothing to do with a hardware defect such as:  
cosmic radiation, electrostatic discharge, or  
software errors. FRU replacement should be  
considered only when a recurring problem exists.  
If this is suspected, clear the error log and run  
the test again. Do not replace any FRUs if log  
errors do not reappear.

Be careful not to replace a nondefective FRU.  
How to Use Error Messages: Use the error  
codes displayed on the screen to diagnose failures. If  
more than one error code is displayed, begin the diagnosis  
with the first error code. The cause of the first error code  
can result in false error codes being displayed. If no error  
code is displayed, see if the error symptom is listed in the  
“Symptom-to-FRU Index” on page 199.  
Port Replicator Problems: If you suspect a  
problem with the Port Replicator, see “Port Replicator  
Checkout” on page 196.  
How to Diagnose Multiple FRUs: When the  
adapter or device has more than one FRU, the error code  
could be caused by either FRU. Before replacing multiple  
FRUs, try removing or exchanging each FRU, one by one  
in the designated sequence, to see if the symptoms  
change.

Device ID (three digit)  
Error code (two digit)  
FRU code (four digit)  
The device ID and error code are used to indicate the  
detail portion of the FRU that caused the error. If  
replacing a FRU does not correct the problem, see the  
device ID or error code from the previous failure. If they  
have changed, the cause might be because the new FRU  
is detective or that the FRU was incorrectly installed.  
Device ID: If an error is detected by the diagnostic  
tests, a three-digits device ID is displayed. The device ID

Intermittent Problems  
Intermittent system hang problems can be caused by a  
variety of reasons that have nothing to do with a hardware  
defect, such as: cosmic radiation, electrostatic discharge,  
or software errors. FRU replacement should be  
considered only when a recurring problem exists.  
When analyzing the intermittent problem, do the following:  
1. Run the advanced diagnostic test for the system  
board in loop mode at least 10 times.  
2. If no error is detected, do not replace any FRUs.  
3. If any error is detected, replace the FRU shown by  
the FRU code. Rerun the test to verify that no more  
errors exist.  
Undetermined Problems  
You are here because the diagnostic tests did not identify  
which adapter or device failed, installed devices are  
incorrect, a short circuit is suspected, or the system is  
inoperative. Follow the procedures below to isolate the  
failing FRU (do not isolate nondefective FRUs).  
Verify that all attached devices are supported by the  
computer.  
Verify that the power supply being used at the time of the  
failure is operating correctly. (See “Power Systems  
Checkout” on page 193.)  
1. Power off the computer.  
2. Check the cables, wires, and connectors for short or  
open circuits. Visually check for damage. If any  
problems are found, replace the FRU.  
3. Remove or disconnect all of the following devices.  
a. Non-IBM devices  
b. Devices attached to the expansion bus  
connector  
c. Printer, mouse, and other external devices  
d. Battery pack  
e. Hard disk drive  
f. Diskette drive  
g. DIMM card  
h. PC Cards  
4. Power on the computer.  
5. Determine if the problem has changed.  
6. If the problem does not occur again, reconnect the  
removed devices one at a time until you find the  
failing FRU.  
7. If the problem remains, replace the following FRUs  
one at a time. Do not replace a non-defective FRU.

Error Log  
Diagnostic errors are printed on the printer that is attached  
to the parallel port when the error is detected. The error is  
also logged in the system memory.  
Do the following to display the errors:  
1. End the test, if it is running.

Checking the Installed Devices List  
If a device is installed but the icon appears in a gray shade  
rather than a dark shade on the basic diagnostics screen,  
the device is defective. Reseat the device connectors. If  
the symptom remains, replace the device or the system  
board. If needed, adjust the contrast control to clearly  
distinguish the shades of the icon.  
If a device that is not installed appears in a dark shade (for  
example, FDD-2 appears in a dark shade when NO  
second FDD is installed), do the following:  
1. Replace the first device in the configuration, such as  
an FDD-1.  
2. If the problem remains, replace the system board.  
The Parallel, and Serial icons are always displayed in a  
dark shade because the icons represent subsystems of the  
system board and not the attachment of the devices.  
The FDD-1 and PCMCIA-1 icons represent the drive in the  
computer. The FDD-2 and PCMCIA-2 icons represent the  
devices in the port replicator or that is attached through the  
port replicator.  
How to Run a Low-Level Format

Warning: Make sure the drive address to be formatted is  
correct. This procedure erases all information on the disk.  
1. Power off the computer.  
2. Insert the ThinkPad Hardware Maintenance  
Diskette Version 1.30 into diskette drive A and  
power on the computer.  
3. Select Format the hard disk from the main menu.  
4. Select the drive from the menu.  
5. Follow the instructions on the screen.

The green LED on the PC test card turns on when the  
PCMCIA test is running. If the LED does not turn on,  
check that the card is installed correctly by reseating the  
card. If it still does not turn on after it is reseated, try  
using another slot for the test. If the LED still does not  
turn on and the test fails, replace the FRU shown by the  
diagnostic error code.  
Fn Key Combinations  
The following table shows the Fn key and function key  
combinations and their corresponding functions.

FRU Removals and Replacements  
This section contains information about removals and  
replacements.  
Ÿ
Do not damage any parts. Only certified and trained  
personnel should service the computer.  
Ÿ
The arrows in the “Removals and Replacements”  
section show the direction of movement to remove a  
FRU, or to turn a screw to release the FRU. The  
arrows are marked in numeric order, in square  
callouts, to show the correct sequence of removal.  
When other FRUs must be removed before removing  
the failing FRU, they are listed at the top of the page.  
To replace a FRU, reverse the removal procedure  
and follow any notes that pertain to replacement.  
See “Locations” for internal cable connections and  
arrangement information.  
Ÿ
Ÿ
Ÿ
When replacing a FRU, use the correct screw size as  
shown in the procedures.  
Safety Notice 1: Translation on page 8  
Before the computer is powered-on after FRU  
replacement, make sure all screws, springs, or other  
small parts, are in place and are not left loose inside  
the computer. Verify this by shaking the computer  
and listening for rattling sounds. Metallic parts or  
metal flakes can cause electrical short circuits.  
Safety Notice 3: Translation on page 10  
The battery pack contains small amounts of nickel.  
Do not disassemble it, throw it into fire or water, or  
short-circuit it. Dispose of the battery pack as  
required by local ordinances or regulations.  
Safety Notice 8: Translation on page 14  
Before removing any FRU, power-off the computer,  
unplug all power cords from electrical outlets, remove  
the battery pack, and then disconnect any  
interconnecting cables.  
Safety Notice 4: Translation on page 11  
The lithium battery can cause a fire, explosion, or  
severe burn. Do not recharge it, remove its polarized  
connector, disassemble it, heat it above 100°C  
(212°F), incinerate it, or expose its cell contents to  
water. Dispose of the battery as required by local  
ordinances or regulations. Use only the battery in the  
appropriate parts listing. Use of an incorrect battery  
can result in ignition or explosion of the battery.

1080 System Board Assembly  
Notes:  
1. The system unit serial number must be restored when  
the system board is replaced. To restore the system  
unit serial number, select the option “Set system  
identification” on the maintenance diskette. The flash  
ROM on the system board contains the vital product  
data (VPD)—that is, the system unit serial number,  
system board system number, and other  
computer-unique data.  
2. Do not power off the computer when restoring the  
VPD. The system unit serial number label is attached  
to the base cover.  
3. Before removing and replacing the system board  
assembly, make sure that the PCMCIA cards are  
removed and the eject levers are not sticking out.

Read This First  
Before you go to the checkout guide, be sure to read this  
section.  
Important Notes  
Ÿ
Ÿ
Ÿ
Only certified trained personnel should  
service the computer.  
Read FRU service procedures before replacing  
any FRUs.  
Be extremely careful during write operations  
such as copying, saving, or formatting. Drives  
in the computer that you are servicing might have  
been rearranged or the drive startup sequence  
might have been altered. If you select an  
incorrect drive, data or programs can be written  
over.  
Ÿ
Ÿ
Replace FRUs only for the correct model.  
When you replace the FRU, make sure the  
model of the machine and FRU part number are  
correct by referring to the part list.  
FRUs should not be replaced because of a  
single, un-reproducible failure. Single failures  
can occur from a variety of reasons that have  
nothing to do with a hardware defect such as:  
cosmic radiation, electrostatic discharge, or  
software errors. FRU replacement should only  
be considered when a recurring problem exists.  
If this is suspected, clear the error log and run  
the test again. Do not replace any FRUs if log  
errors do not reappear.  
Ÿ
Be careful not to replace a non-defective FRU.  
How to Use Error Messages: Use the error  
codes displayed on the screen to diagnose failures. If  
more than one error code is displayed, begin the diagnosis  
with the first error code. The cause of the first error code  
can result in false error codes being displayed. If no error  
code is displayed, see if the error symptom is listed in the  
“Symptom-to-FRU Index” on page 279.  
Port Replicator Problems: If you suspect a  
problem with the Port Replicator, see “Port Replicator  
Checkout” on page 275.  
How to Diagnose Multiple FRUs: When the  
adapter or device has more than one FRU, the error code  
could be caused by either FRU. Before replacing multiple  
FRUs, try removing or exchanging each FRU, one by one  
in the designated sequence, to see if the symptoms  
change.

What to Do First: The servicer must include the  
following in the parts exchange form or parts return form  
that is attached to the returned FRU.  
1. Name and phone number of servicer.  
2. Date of service.  
3. Date when part failed.  
4. Date of purchase.  
5. Failure symptoms, error codes appearing on  
display, and beep symptoms.  
6. Procedure index and page number in which  
failing FRU was detected.  
7. Failing FRU name and part number.  
8. Machine type, model number, and serial number.  
9. Customer's name and address.  
Before checking problems with the computer, determine  
whether or not the damage applies the warranty by  
referring to the following:  
Warranty Note  
During the warranty period, the customer may be  
responsible for repair costs if the computer damage  
was caused by misuse, accident, modification,  
unsuitable physical or operating environment, or  
improper maintenance by the customer. The following  
list provides some common items that are not covered  
under warranty and some symptoms that may indicate  
the system was subjected to stresses beyond normal  
use:  
Ÿ
LCD panel cracked by applying excessive force  
or by being dropped.  
Ÿ
Ÿ
Scratched (cosmetic) parts.  
Cracked or broken plastic parts, broken latches,  
broken pins, or broken connectors caused by  
excessive force.  
Ÿ
Ÿ
Damage caused by liquid spilled into the system.  
Damage caused by improperly inserting a  
PCMCIA card or installation of an incompatible  
card.  
Ÿ
Ÿ
Damage caused by foreign material in the FDD.  
Diskette drive damage caused by pressing the  
diskette drive cover or inserting diskettes with  
multiple labels.  
Ÿ
Ÿ
Damaged or bent diskette eject button.  
Fuses blown by attaching a non-supported  
device.  
Ÿ
Forgotten computer password, making computer  
unusable.

If the following symptoms are present, they may  
indicate damage caused by non-warranted  
activity:  
Ÿ
Ÿ
Ÿ
Missing parts may be a symptom of unauthorized  
service or modification.  
HDD spindles can become noisy if subjected to  
excessive force or by being dropped.  
I9990303 errors can be caused by exposure to  
strong magnetic fields.  
How to Disable the Power-On Password  
Important  
This information is not available in this online HMM  
format. See your IBM Servicer or IBM Authorized  
Dealer for this this procedure.  
Power Shutdown Switch: The power shutdown  
switch resets the system regardless of the microcode  
status and forces the power off. Use this push button to  
power-off when power is not completely off or the  
microcode is in a hung state.  
See “Bottom View” on page 322 for the power shutdown  
switch.

Checkout Guide  
Use the following procedure as a guide for computer  
problems.  
Note  
The diagnostic tests are intended to test only IBM  
products. Non-IBM products, prototype cards, or  
modified options can give false errors and invalid  
system responses.  
1. Obtain the failing symptoms in as much detail as  
possible.  
2. Verify the symptoms by attempting to recreate the  
failure by running the diagnostic test or by repeating  
the same operation.  
Note  
To run the diagnostics, refer to “How to Run the  
Diagnostics” on page 292.  
3. Use the following table with the verified symptom to  
determine which page to go to. Search the  
symptoms column and find the description that best  
matches your symptom; then go to the page shown in  
the “Go to” column.

Memory errors might stop system operations, show error  
messages on the screen, or hang the system.  
Use the following procedure to isolate memory problems.  
Note  
Make sure that the DIMM card is fully installed into the  
connector. A loose connection can cause an error.  
1. Power off the computer and remove the DIMM card  
from its slot (if installed).  
2. Press and hold the F1 key; then power on the  
computer. Hold the F1 key down until the

If any of the above devices do not work, reseat the cable  
connector and repeat the failing operation.  
If the problem does not occur again, recheck the  
connector.  
If the problem is not corrected, replace the device, and  
then the system board.  
TrackPoint III Checkout  
If the TrackPoint III will not work, check the configuration in  
the ThinkPad Features program. If the configuration of the  
TrackPoint III is disabled, select Enable to enable it.  
If this does not correct the TrackPoint III problem, continue  
with the following.  
The TrackPoint III does automatic compensations to adjust  
the pointer sensor. During this process, the pointer moves  
on the screen automatically for a short time. This  
self-acting pointer movement can occur when a slight,  
steady pressure is applied to the TrackPoint III pointer  
while the computer is powered on or while the system is  
running, or when re-adjustment is required because the  
temperature has exceeded its normal temperature range.  
This symptom does not indicate a hardware problem. No  
service actions are necessary if the pointer movement  
stops in a short period of time.  
If a click button problem or pointing stick problem occurs,  
do the following:  
1. Go to the Easy-Setup screen.  
2. Select an item with the pointing stick.  
3. Press either the left or right click button.  
4. Verify that both buttons work correctly.  
If either the pointing stick or the click button do not work,  
do the following actions one at a time to correct the  
problem. Do not replace a non-defective FRU.

FDD-1 represents external diskette drive attached through  
the external diskette drive connector. FDD-2 represents  
the port replicator.  
Warning: Make sure that the diskette does not have  
more than one label attached to it. Multiple labels can  
cause damage to the drive or can cause the drive to fail.  
Do the following to select the test device:  
1. Select the advanced diagnostics mode and select  
Tool; then select the FDD-1 or FDD-2 icon and press  
the spacebar. A √ mark appears next to the selected  
icon. Insert the blank diskette when instructed.  
2. Run the diskette drive test.  
3. If the controller test detects an error, FRU code 10  
appears. Replace the system board.  
4. If the controller test runs without errors, the drive  
read/write tests start automatically.  
5. If the drive test detects an error, FRU code 50 for  
FDD-1 or 51 for FDD-2 appears. If the diskette itself  
is known to be good, replace the drive.  
6. If FDD-2 test detects an error, move the drive to the  
computer's diskette drive connector directly, if  
possible, and test it again as FDD-1.  
If no errors occur in the FDD-1 position, the drive is  
not defective. Go to “Port Replicator Checkout” on  
page 275 to isolate the replicator problem.  
Status Indicator Checkout  
If an LED problem occurs, do the following:  
1. Power off the computer  
2. Power on the computer  
3. All the LEDs in the indicator panel turn on for a  
moment soon after the computer is powered-on.  
Make sure that all LEDs turn on.  
If the problems remains, replace the system board.  
Power Systems Checkout  
To verify the symptom of the problem, power on the  
computer using each of the power sources as follows.  
1. Remove the battery pack and diskette drive.  
2. Connect the AC Adapter and check that power is

2. Unplug the AC Adapter cable from the ac power  
outlet and wait five minutes or longer to allow the  
over-voltage protection circuit to be fully discharged  
and initialized.  
3. Plug the AC Adapter cable into the ac power outlet.  
4. Measure the output voltage of the AC Adapter.  
5. If the voltage is still not correct, replace the AC  
Adapter.  
Note  
An audible noise from the AC Adapter does not  
always indicate a defective adapter.  
Checking Operational Charging: To check  
operational charging, use a discharged battery pack or a  
battery pack that has less than 50% of the total power  
remaining when installed in the computer.  
ThinkPad 560 (2640) 273  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Perform operational charging. If the battery status  
indicator does not turn on, remove the battery pack and  
leave it to return to room temperature. Reinstall the  
battery pack. If the charge indicator still does not turn on,  
replace the battery pack.  
Checking the Battery Pack: Battery charging will  
not start until the Fuel-Gauge shows that less than 95% of  
the total power remains; with this condition the battery  
pack will charge to 100% of its capacity. This protects the  
battery pack from being over-charged or having a  
shortened life.  
Do the following:  
1. Power off the computer.  
2. Remove the battery pack and measure the voltage  
between battery terminals 1 (+) and 4 (−). See the  
following figure.

3. If the voltage is less than +11.0 V dc, the battery pack  
has been discharged. Recharge the battery pack.  
If the voltage is still less than +11.0 V dc after  
recharging, replace the battery.  
Note  
If the voltage of the battery pack is 0 V, it is not  
defective.

resistance must be 4 to 30 K ohm.  
If the resistance is not correct, replace the battery  
pack. If the resistance is correct, replace the system  
board.  
Checking the Backup Battery  
1. Power off the computer and unplug the AC Adapter  
from the computer.  
2. Turn the computer upside down.

LCD-Related Symptoms  
Important  
The LCD for the notebook computer contains over  
921000 thin-film transistors (TFTs). A small number  
of missing, discolored, or lighted dots (on all the time)  
is characteristic of TFT LCD technology, but excessive  
pixel problems can cause viewing concerns. The LCD  
should be replaced if the number of dots satisfies the  
following condition:  
Ÿ
The number of missing, discolored, or lighted  
dots in any background is 21 or more.

Note  
If you cannot find a symptom or error in this list and  
the problem remains, see “Undetermined Problems”  
on page 290.  
Intermittent Problems  
Intermittent system hang problems can be caused by a  
variety of reasons that have nothing to do with a hardware  
defect, such as: cosmic radiation, electrostatic discharge,  
or software errors. FRU replacement should only be  
considered when a recurring problem exists.  
When analyzing the intermittent problem, do the following:  
1. Run the advanced diagnostic test for the system  
board in loop mode at least 10 times.  
2. If no error is detected, do not replace any FRUs.  
3. If any error is detected, replace the FRU shown by  
the FRU code. Rerun the test to verify that no more  
errors exist.

Download from Www.Somanuals.com. All Manuals Search And Download.  
Undetermined Problems  
You are here because the diagnostic tests did not identify  
which adapter or device failed, installed devices are  
incorrect, a short circuit is suspected, or the system is  
inoperative. Follow the procedures below to isolate the  
failing FRU (do not isolate non-defective FRUs).  
Verify that all attached devices are supported by the  
computer.  
Verify that the power supply being used at the time of the  
failure is operating correctly. (See “Power Systems  
Checkout” on page 272.)  
1. Power off the computer.  
2. Check the cables, wires, and connectors for short  
circuits and open circuits. Visually check them for  
damage. If any problems are found, replace the  
FRU.  
3. Remove or disconnect all of the following devices.  
a. Non-IBM devices  
b. Devices attached to the expansion bus  
connector  
c. Printer, mouse, and other external devices  
d. Battery pack  
e. Hard disk drive  
f. Diskette drive  
g. DIMM card  
h. PC Cards  
4. Power on the computer.  
5. Determine if the problem has changed.  
6. If the problem does not occur again, reconnect the  
removed devices one at a time until you find the  
failing FRU.  
7. If the problem remains, replace the following FRUs  
one at a time. Do not replace a non-defective FRU.

step to select multiple devices. Press Enter to start  
the diagnostic loop. If no device is selected, all  
device tests are looped.  
13. To exit the loop, keep pressing Ctrl+Pause until the  
test exits. A beep sounds to notify that the exit  
interrupt is sensed by the test program.  
Error Log  
Diagnostic errors are printed on the printer that is attached  
to the parallel port when the error is detected. The error is  
also logged in the system memory.  
Do the following to display the errors.  
1. End the test, if it is running.  
2. Press Ctrl+A to select the advanced diagnostic mode.  
3. Press Ctrl+E.  
4. The error log appears.  
5. To exit the screen, select the cancel icon or press  
Esc.  
The error log is not saved when the system is powered-off.  
Checking the Installed Devices List  
If a device is installed but the icon appears in a gray shade  
rather than a dark shade on the basic diagnostics screen,  
the device is defective. Reseat the device connectors. If  
the symptom remains, replace the device or the system  
board. If needed, adjust the contrast control to clearly  
distinguish the shades of the icon.  
If a device that is not installed appears in a dark shade (for  
example, FDD-2 appears in a dark shade when NO  
second FDD is installed), do the following:  
1. Replace the first device in the configuration, such as  
an FDD-1.  
2. If the problem remains, replace the system board.  
The Parallel, and Serial icons are always displayed in a  
dark shade because the icons represent subsystems of the  
system board and not the attachment of the devices.  
ThinkPad 560 (2640) 293  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The FDD-1 icon represent the first drive in the system  
configuration for each type of device. For ThinkPad 560,  
FDD-1 represents an external diskette drive attached  
through the external diskette drive connector. Similarly,  
the FDD-2 icon represent the second drive, usually  
attached through a port replicator.  
How to Run a Low-Level Format

Warning: Make sure the drive address to be formatted is  
correct. This procedure will erase all information on the  
disk.  
1. Power off the computer.  
2. Insert the ThinkPad hardware maintenance  
diskette Ver 1.20 into diskette drive A and power on  
the computer.  
3. Select Format the hard disk from the main menu.  
4. Select the drive from the menu.  
5. Follow the instructions on the screen.  
PC Test Card LED  
The green LED on the PC test card turns on when the  
PCMCIA test is running. If the LED does not turn on,  
check that the card is installed correctly by reseating the  
card. If it still does not turn on after it is reseated, try  
using another slot for the test. If the LED still does not  
turn on and the test fails, replace the FRU shown by the  
diagnostic error code.

The system unit serial number must be restored  
when the system board is replaced. To restore  
the system unit serial number, select the option  
“Set system identification” on the maintenance  
diskette. The flash ROM on the system board  
contains the vital product data (VPD), that is, the  
system unit serial number, system board system  
number, and other computer-unique data.  
Do not power off the computer when restoring  
the VPD. The system unit serial number label is  
attached to the base cover.

1120 LCD Front Cover  
Important  
The LCD for the notebook computer contains over  
921,000 thin-film transistors (TFTs). A small number  
of missing, discolored, or constantly lighted dots is  
characteristic of TFT LCD technology, but excessive  
pixel problems can cause viewing concerns. The LCD  
should be replaced if the number of missing,  
discolored, or lighted dots in any background is 21 or  
more.

Read This First  
Before you go to the checkout guide, be sure to read this  
section.  
Important Notes  
Ÿ
Ÿ
Ÿ
Only certified trained personnel should  
service the computer.  
Read FRU service procedures before replacing  
any FRUs.  
Be extremely careful during write operations  
such as copying, saving, or formatting. Drives  
in the computer that you are servicing might have  
been rearranged or the drive startup sequence  
might have been altered. If you select an  
incorrect drive, data or programs can be written  
over.  
Ÿ
Ÿ
Replace FRUs only for the correct model.  
When you replace the FRU, make sure the  
model of the machine and FRU part number are  
correct by referring to the part list.  
FRUs should not be replaced because of a  
single, unreproducible failure. Single failures  
can occur from a variety of reasons that have  
nothing to do with a hardware defect such as:  
cosmic radiation, electrostatic discharge, or  
software errors. FRU replacement should be  
considered only when a recurring problem exists.  
If this is suspected, clear the error log and run  
the test again. Do not replace any FRUs if log  
errors do not reappear.  
Ÿ
Be careful not to replace a nondefective FRU.  
How to Use Error Messages: Use the error  
codes displayed on the screen to diagnose failures. If  
more than one error code is displayed, begin the diagnosis  
with the first error code. The cause of the first error code  
can result in false error codes being displayed. If no error  
code is displayed, see if the error symptom is listed in the  
“Symptom-to-FRU Index” on page 359.  
Port Replicator Problems: If you suspect a  
problem with the Port Replicator, see “Port Replicator  
Checkout” in the “Common Devices Checkout” section for  
more information.  
How to Diagnose Multiple FRUs: If the adapter  
or device has more than one FRU, the error code could be  
caused by either FRU. Before replacing multiple FRUs, try  
removing or exchanging each FRU, one by one in the  
designated sequence, to see if the symptoms change.

What to Do First: The servicer must include the  
following in the parts exchange form or part return form  
that is attached to the returned FRU:  
1. Name and phone number of servicer  
2. Date of service  
3. Date when part failed  
4. Date of purchase  
5. Failure symptoms, error codes appearing on  
display, and beep symptoms  
6. Procedure index and page number in which  
failing FRU was detected  
7. Failing FRU name and part number  
8. Machine type, model number, and serial number  
9. Customer's name and address  
Before checking problems with the computer, determine  
whether the damage applies the warranty by referring to  
the following:  
Note for Warranty: During the warranty period, the  
customer may be responsible for repair costs if the  
computer damage was caused by misuse,  
accident, modification, unsuitable physical or  
operating environment, or improper maintenance by  
the customer. The following list provides some  
common items that are not covered under warranty  
and some symptoms that may indicate the system  
was subjected to stresses beyond normal use:  
The following is not covered under warranty:  
Ÿ
LCD panel cracked by applying excessive force  
or by being dropped  
Ÿ
Ÿ
Scratched (cosmetic) parts  
Cracked or broken plastic parts, broken latches,  
broken pins, or broken connectors caused by  
excessive force  
Ÿ
Ÿ
Damage caused by liquid spilled into the system  
Damage caused by improperly inserting a  
PCMCIA card or installation of an incompatible  
card  
Ÿ
Ÿ
Damage caused by foreign material in the FDD  
or UltraBay  
Diskette drive damage caused by pressing the  
diskette drive cover or inserting diskettes with  
multiple labels  
Ÿ
Ÿ
Damaged or bent diskette eject button  
CD-ROM drive damage caused by excessive  
forces shock, or by being dropped  
Fuses blown by attaching a nonsupported device

If the following symptoms are present, they may  
indicate damage caused by nonwarranted activity:  
Ÿ
Ÿ
Ÿ
Missing parts may be a symptom of unauthorized  
service or modification.  
HDD spindles can become noisy if subjected to  
excessive force or by being dropped.  
I9990303 errors can be caused by exposure to  
strong magnetic fields.  
How to Disable the Power-On Password:  
Important  
This information is not available in this online HMM  
format. See your IBM Servicer or IBM Authorized  
Dealer for this procedure.  
Supervisor and Hard Disk Passwords: The  
supervisor password and the hard disk password (HDP)  
are security features that are used to protect the system  
and the hard disk data from unauthorized access. No  
overriding capability is provided. If only a hard disk  
password is set, obtaining permission from the password  
owner to unlock the password is a prerequisite for running  
diagnostic tests and performing service. If both supervisor  
password and hard disk password are set, you can enter  
Easy-Setup by pressing the Enter key or power-on  
password at the supervisor password prompt. In this case,  
the Password, Start up, and Initialize icons cannot be  
selected.  
See “Password Combinations (POP, HDP, PAP)” on  
page 375 for more information about passwords.  
Power Shutdown Switch: The power shutdown  
switch resets the system regardless of the microcode  
status and forces the power off. Use this push button to  
power-off when power is not completely off or the  
microcode is in a hung state.  
See “Rear View” on page 479 for the power shutdown  
switch.

Checkout Guide  
Use the following procedure as a guide for computer  
problems.  
Note: The diagnostic tests are intended to test only IBM  
products. Non-IBM products, prototype cards, or  
modified options can give false errors and invalid  
system responses.  
1. Obtain the failing symptoms in as much detail as  
possible.  
2. Verify the symptoms by attempting to re-create the  
failure by running the diagnostic test or by repeating  
the same operation.  
Note: To run the diagnostics, refer to “How to Run  
the Diagnostics” on page 373.  
3. Use the following table with the verified symptom to  
determine which page to go to. Search the

Memory errors might stop system operations, show error  
messages on the screen, or hang the system.  
Use the following procedure to isolate memory problems:  
Note: Make sure that the DIMM adapter card is fully  
installed into the connector. A loose connection  
can cause an error.  
1. Power-off the computer and remove the DIMM  
adapter card from its slot (if installed).  
2. Press and hold the F1 key; then power-on the  
computer. Hold the F1 key down until the  
Easy-Setup screen appears.  
3. Select Test and press Enter.  
4. Select Memory and press Enter to run the memory  
test on base memory. If an error appears, replace  
the system board.  
5. Power-off the computer and reinstall the DIMM  
adapter card; then power-on the computer. Verify the  
memory size; then test the memory. If an error  
appears, replace the DIMM adapter card.  
If memory problems occur intermittently, use the loop  
option to repeat the test. When the test detects an error,  
an error log is printed on the printer connected to the  
parallel port. See “Error Log” on page 374 for more  
information.  
System Programs in Flash Memory: System setup  
programs and diagnostic tests are stored in flash memory.  
Flash Memory Update: A flash memory update is  
required for the following conditions:  
Ÿ
Ÿ
New versions of system programs.  
New features or options are added.  
To update the flash memory, do the following:  
1. Get the appropriate diskette containing the update.  
2. Insert the System Program Service Diskette into drive  
A and power-on the computer.  
3. Select Update system programs from the menu.  
System Board and CPU Card Checkout  
The processing functions are performed by both the  
system board and the CPU card. Processor problems can  
be caused by either FRU. However, the CPU card  
generally has a lower probability of failure. When a  
numeric code calls the system board or the CPU card as a  
FRU, or the CPU card is called by a diagnostic test by  
showing FRU code 11, use the following procedure to  
isolate the problem:  
1. Run the system board test to verify the symptom.  
This test verifies both the system board and the CPU  
card. If no error is detected, return to “Checkout  
Guide” on page 341.  
344 IBM Mobile Systems - ThinkPad HMM Volume 3  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Note: Don't touch the keyboard and pointing device  
when the system board test is running. This  
may cause an unexpected error.  
2. If FRU code 10 appears, replace the system board  
but do not replace the CPU card. Transfer the CPU  
card from the old system board to the new system  
board.  
3. If FRU code 11 appears, reseat the CPU card.  
4. Rerun the test to verify the fix.  
5. If FRU code 11 remains, replace the CPU card.  
If this procedure does not correct the problem, go to  
“Undetermined Problems” on page 371.  
Keyboard and Auxiliary Input Device  
Checkout  
Remove the external keyboard if the internal keyboard is to  
be tested.  
If the internal keyboard does not work or an unexpected  
character appears, make sure that the flexible cable  
extending from the keyboard is correctly seated in the  
connector on the video card.  
If the keyboard cable connection is correct, check the DSP  
card (see “DSP Card Checkout” on page 346) or Audio  
(ESS) card (see “Audio (ESS) Card Checkout” on  
page 346).  
If the tests do not detect a keyboard problem, run the  
keyboard test by doing the following:  
1. Go to the diagnostic menu screen by selecting Test  
in the Easy-Setup menu.  
2. Press Ctrl+A to enter to the advanced diagnostic  
mode.  
3. Press Ctrl+K; a layout of the keyboard appears on  
the screen.  
4. Check that when each key is pressed, the key's  
position on the keyboard layout on the screen  
changes to a black square.  
Note: When the Fn key is pressed, a black square  
briefly appears.  
If the tests detect a keyboard problem, do the following  
one at a time to correct the problem. Do not replace a  
nondefective FRU.  
Ÿ
Ÿ
Ÿ
Ÿ
Ÿ
Reseat the keyboard card cable.  
Replace the keyboard card cable.  
Replace the keyboard card assembly.

Numeric keypad  
Mouse (PS/2 compatible)  
External keyboard (with keyboard/mouse cable)  
If any of these devices do not work, reseat the cable  
connector and repeat the failing operation.  
If the problem does not recur, recheck the connector.  
If the problem is not corrected, replace the device, and  
then the system board.  
DSP Card Checkout  
(Models 760C/760CD/760E/760ED/760XD)  
1. Go to the diagnostic menu screen by selecting Test  
in the Easy-Setup menu.  
2. Select DSP and run the diagnostic tests.  
3. If the test detects a DSP card problem,  
replace the DSP card.  
Audio (ESS) Card Checkout  
(Models 760L/760LD/760EL/760ELD/760XL)  
1. Go to the diagnostic menu screen by selecting Test  
in the Easy-Setup menu.  
2. Select Audio and run the diagnostic tests.  
3. If the test detects a audio (ESS) card problem,  
replace the audio (ESS) card.  
TrackPoint III Checkout  
If the TrackPoint III does not work, check the configuration  
in the ThinkPad Features program. If the configuration of  
the TrackPoint III is disabled, select Enable to enable it.  
If this does not correct the TrackPoint III problem, continue  
with the following.  
The TrackPoint III does automatic compensations to adjust  
the pointer sensor. During this process, the pointer moves  
on the screen automatically for a short time. This  
self-acting pointer movement can occur when a slight,  
steady pressure is applied to the TrackPoint III pointer  
while the computer is powered on or while the system is

Checking the AC Adapter: You are here  
because the computer fails only when the AC Adapter is  
used.  
Ÿ
If the power problem occurs only when the port  
replicator is used, replace the replicator.  
If the power-on indicator does not turn on, check the  
power cord of the AC Adapter for correct continuity  
and installation.

If the operational charge does not work, go to  
“Checking Operational Charging” on page 351.  
Note: For Model 760CD, 760ED, 760LD, 760ELD, 760XL,  
and 760XD, there are two types of adapters. The  
procedure for checking both types is the same.  
1. Unplug the AC Adapter cable from the computer and  
measure the output voltage at the plug of the AC  
Adapter cable. See the following figure:

Replace the DC/DC card.  
If the problem is not corrected, replace the  
system board.  
Ÿ
Ÿ
If the problem is still not corrected, go to  
“Undetermined Problems” on page 371.  
If the voltage is not correct, go to the next step.  
2. Unplug the AC Adapter cable from the ac power  
outlet and wait five minutes or longer to allow the  
over-voltage protection circuit to be fully discharged  
and initialized.  
3. Plug the AC Adapter cable into the ac power outlet.  
4. Measure the output voltage of the AC Adapter.  
5. If the voltage is still not correct, replace the AC  
Adapter.  
Note: An audible noise from the AC Adapter does not  
always indicate a defective adapter.  
Checking Operational Charging: To check  
operational charging, use a discharged battery pack or a  
battery pack that has less than 50% of the total power  
remaining when installed in the computer.  
Perform operational charging. If the battery status  
indicator does not turn on, remove the battery pack and  
leave it to return to room temperature. Reinstall the  
battery pack. If the charge indicator still does not turn on,  
replace the battery pack.  
Checking the Battery Pack: Battery charging will  
not start until the Fuel-Gauge shows that less than 95% of  
the total power remains; with this condition the battery  
pack will charge to 100% of its capacity. This protects the  
battery pack from being overcharged or having a  
shortened life.  
Do the following:  
1. Power-off the computer.  
2. Remove the battery pack and measure the voltage  
between battery terminals 1 (+) and 4 (−). See the  
following figure:

3. If the voltage is less than +11.0 V dc, the battery pack  
has been discharged. Recharge the battery pack.  
If the voltage is still less than +11.0 V dc after  
recharging, replace the battery.  
Note: If the voltage of the battery pack is 0 V, it is  
not defective.  
4. If the voltage is more than +11.0 V dc, measure the  
resistance between battery terminals 3 and 4. The  
resistance must be 4 to 30 K ohm.  
If the resistance is not correct, replace the battery  
pack.  
If the resistance is correct, replace the DC/DC card.  
Checking the Car-Battery Adapter  
1. Unplug the Car-Battery Adapter cable from the  
computer.  
2. Plug the Car-Battery Adapter into the cigarette lighter  
socket.  
Note: If the adapter is already plugged in, reseat it.  
3. Measure the output voltage of the Car-Battery  
Adapter cable. See the following figure:

status is restored from the hard disk to resume operation.  
Port Replicator Power Overload: If power  
shutdowns occur intermittently when using PCMCIA-2  
devices via a port replicator, suspect a current overload.  
Some PCMCIA devices use much power; if the maximum  
usage of each device occurs simultaneously, the total  
current will exceed the limit, thereby causing a power  
shutdown. Isolate this problem by removing one of the  
devices, and use the computer under the same condition  
to see whether a power shutdown occurs. Do this  
procedure for all devices; then determine the cause.

LCD-Related Symptoms  
Important  
The LCD for the notebook computer contains over  
921,000 thin-film transistors (TFTs). A small number  
of missing, discolored, or lighted dots (on all the time)  
is characteristic of TFT LCD technology, but excessive  
pixel problems can cause viewing concerns. The LCD  
should be replaced if the number of missing,  
discolored, or lighted dots in any background is 21 or  
more.

Note: If you cannot find a symptom or error in this list  
and the problem remains, see “Undetermined

Intermittent Problems  
Intermittent system hang problems can be caused by a  
variety of reasons that have nothing to do with a hardware  
defect, such as cosmic radiation, electrostatic discharge, or  
software errors. FRU replacement should only be  
considered when a recurring problem exists.  
When analyzing the intermittent problem, do the following:  
1. Run the advanced diagnostic test for the system  
board in loop mode at least 10 times.  
2. If no error is detected, do not replace any FRUs.  
3. If any error is detected, replace the FRU shown by  
the FRU code. Rerun the test to verify that there are  
no more errors.

Undetermined Problems  
You are here because the diagnostic tests did not identify  
which adapter or device failed, installed devices are  
incorrect, a short circuit is suspected, or the system is  
inoperative. Follow the procedures below to isolate the  
failing FRU (do not isolate nondefective FRUs).  
Verify that all attached devices are supported by the  
computer.  
Verify that the power supply being used at the time of the  
failure is operating correctly. (See “Power Systems  
Checkout” on page 349.)  
1. Power-off the computer.  
2. Check the cables, wires, and connectors for short  
circuits and open circuits. Visually check them for  
damage. If any problems are found, replace the  
FRU.  
3. Remove or disconnect all of the following devices:  
a. Non-IBM devices  
b. Devices attached to the expansion bus  
connector  
c. Printer, mouse, and other external devices  
d. Battery pack  
e. Hard disk drive  
f. Diskette drive/CD-ROM drive or the device  
attached in the UltraBay.  
g. DIMM  
h. PC Cards  
4. Power-on the computer.  
5. Determine if the problem has changed.  
6. If the problem does not occur again, reconnect the  
removed devices one at a time until you find the  
failing FRU.  
7. If the problem remains, replace the following FRUs  
one at a time. Do not replace a nondefective FRU.

How to Run the Diagnostics  
Use either the TrackPoint III or the cursor move keys to  
interact with the tests. The Enter key works the same as  
selecting the OK icon to reply OK.  
1. Press and hold the F1 key; then power-on the  
computer. Hold the F1 key down until the  
Easy-Setup screen appears.  
2. Select Test and press Enter.  
3. Select a device and press Enter to run the test.  
4. The test progress screen appears.  
5. “OK” appears when the test ends without any errors.  
6. Start the Advanced Diagnostic test by pressing  
Ctrl+A on the basic diagnostic menu screen.  
7. Select Tool to install the tools.  
Note: The following tools are required.  
FDD:

Any CD (data CD is  
recommended)  
8. Select a device, press the Spacebar, and install the  
tool. Multiple devices can be selected by repeating  
this step.  
A √ mark appears beside the selected devices.  
9. Select OK and press Enter if the selection is OK.  
ThinkPad 760 (9546, 9547) 373  
Download from Www.Somanuals.com. All Manuals Search And Download.  
10. Select a device and press Enter to start the tests.  
Note: Don't touch the keyboard and pointing device  
when the system board test in running. This  
may cause an error.  
11. Select Test All to test all devices.  
12. Select Loop Test to run the tests in a repeated loop.  
A loop option menu appears where you can select a  
device loop or all-device loop. Select a device by  
pressing the Spacebar. Repeat this step to select  
multiple devices. Press Enter to start the diagnostic  
loop. If no device is selected, all device tests are  
looped.  
13. To exit the loop, keep pressing Ctrl+Pause until the  
test exits. A beep sounds to notify that the exit  
interrupt is sensed by the test program.  
Error Log  
Diagnostic errors are printed on the printer that is attached  
to the parallel port when the error is detected. The error is  
also logged in the system memory.  
Do the following to display the errors.  
1. End the test, if it is running.  
2. Press Ctrl+A to select the advanced diagnostic mode.  
3. Press Ctrl+E.  
4. The error log appears.  
5. To exit the screen, select the cancel icon or press  
Esc.  
The error log is not saved when the system is powered-off.  
Checking the Installed Devices List  
If a device is installed but the icon appears in a gray shade  
rather than a dark shade on the basic diagnostics screen,  
the device is defective. Reseat the device connectors. If  
the symptom remains, replace the device or the system  
board. If needed, adjust the contrast control to clearly  
distinguish the shades of the icon.  
If a device that is not installed appears in a dark shade (for  
example, FDD-2 appears in a dark shade when no second  
FDD is installed), do the following:  
1. Replace the first device in the configuration, such as  
an FDD-1, an HDD-1, or a PCMCIA-1.  
2. If the problem remains, replace the system board.  
The PCMCIA-1, Parallel, and Serial icons are always  
displayed in a dark shade because the icons represent  
subsystems of the system board and not the attachment of  
the devices.  
The FDD-1, HDD-1, or PCMCIA-1 icons represent the first  
drive in the system configuration for each type of device.  
Similarly, the FDD-2 or PCMCIA-2 icons represent the

second drive, usually attached through a port replicator or  
an expansion unit. The HDD-2 icon represents the hard  
disk drive in the UltraBay. The HDD-3 and HDD-4 icons  
represent the hard disk drive, attached through an  
expansion unit.

Notes:  
1. The system unit serial number must be restored when  
the system board is replaced. To restore the system  
unit serial number, select the option “Set system  
identification” on the maintenance diskette. The  
EEPROM on the system board contains the vital  
product data (VPD), the system unit serial number,  
system board system number, and other  
computer-unique data.  
Note: Do not power off the computer when restoring  
the VPD.  
The system unit serial number label is attached to the  
base cover.  
2. Before removing and replacing the system board,  
make sure that the PCMCIA cards are removed and  
the eject levers are not sticking out.  
3. Do not pull the PCMCIA slot assembly while removing  
the system board.  
4. When handling the PCMCIA slot assembly, be careful  
not to disassemble any part of it. The slot assembly  
is not solidly fixed when it is removed from the  
system board or the FRU.  
5. Be sure to unlock both ends of the PCMCIA  
connector before removing the PCMCIA slot  
assembly from the system board (.2/).

Read This First  
Before you go to the checkout guide, be sure to read this  
section.  
Important Notes  
Ÿ
Ÿ
Ÿ
Only certified, trained personnel should  
service the computer.  
Read FRU service procedures before replacing  
any FRUs.  
Be extremely careful during write operations  
such as copying, saving, or formatting.  
Drives in the computer that you are servicing  
might have been rearranged or the drive startup  
sequence might have been altered. If you select  
an incorrect drive, data or programs can be  
written over.  
Ÿ
Ÿ
Use only the correct FRUs. When you replace  
a FRU, make sure the model of the machine and  
FRU part number are correct by referring to the  
parts listing.  
FRUs should not be replaced because of a  
single, un-reproducible failure. Single failures  
can occur from a variety of reasons that have  
nothing to do with a hardware defect such as:  
cosmic radiation, electrostatic discharge, or  
software errors. FRU replacement should only  
be considered when a recurring problem exists.  
If this is suspected, clear the error log and run  
the test again. Do not replace any FRUs if log  
errors do not reappear.  
Ÿ
Be careful not to replace a non-defective FRU.  
How to Use Error Messages: Use the error  
codes displayed on the screen to diagnose failures. If  
more than one error code is displayed, begin the diagnosis  
with the first error code. The cause of the first error code  
can result in false error codes being displayed. If no error  
code is displayed, see if the error symptom is listed in the  
“Symptom-to-FRU Index” on page 565.  
How to Diagnose Multiple FRUs: When the  
adapter or device has more than one FRU, the error code  
could be caused by either FRU. Before replacing multiple  
FRUs, try removing or exchanging each FRU, one by one  
in the designated sequence, to see if the symptoms  
change.  
What to Do First: The servicer must include the  
following in the parts exchange form or part return form  
that is attached to the returned FRU.  
1. Name and phone number of servicer.  
2. Date of service.  
548 IBM Mobile Systems - ThinkPad HMM Volume 3  
Download from Www.Somanuals.com. All Manuals Search And Download.  
3. Date when part failed.  
4. Date of purchase.  
5. Failure symptoms, error codes appearing on  
display, and beep symptoms.  
6. Procedure index and page number in which  
failing FRU was detected.  
7. Failing FRU name and part number.  
8. Machine type, model number, and serial number.  
9. Customer's name and address.  
Before servicing with the computer, determine if the  
warranty applies by referring to the following:  
Warranty Note  
During the warranty period, the customer may be  
responsible for repair costs if the computer damage  
was caused by misuse, accident, modification,  
unsuitable physical or operating environment, or  
improper maintenance by the customer. The following  
list provides some common items that are not covered  
under warranty and some symptoms that might  
indicate the system was subjected to stresses beyond  
normal use:

Notes  
If the following symptoms are present, they might  
indicate damage caused by non-warranted activity:  
Ÿ
Ÿ
Ÿ
Missing parts might be a symptom of  
unauthorized service or modification.  
HDD spindles can become noisy if subjected to  
excessive force or by being dropped.  
I9990303 errors can be caused by exposure to  
strong magnetic fields.  
General Preparation  
In this manual, IBM ThinkPad Dock I means that  
SelectaDock Base Model I and SelectaDock I together  
when docked as one unit.  
1. Check that the SelectaDock Base Model I is correctly  
docked (connected) to the SelectaDock I.  
2. Check that the computer is correctly docked  
(connected) to the IBM ThinkPad Dock I.  
3. Dock a working computer to the SelectaDock Base  
Model I only, and verify there are no problems. If  
there are any problems, replace the SelectaDock  
Base Model I.  
4. If possible, make sure there are no hardware setting  
conflicts, such as in interrupt levels, memory  
addresses, DMA channels, and I/O addresses.  
5. Check that the SCSI ID is set correctly.  
6. Test and correct any computer problems before you  
test it with IBM ThinkPad Dock I. Use the computer  
documentation to resolve any computer problems.  
7. Test the computer with the external keyboard,  
external display, mouse, and parallel and serial  
device connectors. (Use the keyboard/mouse  
connector to test the external keyboard and mouse.)  
If no problems are found, connect the external  
keyboard, mouse, parallel and serial devices to IBM  
ThinkPad Dock I, then connect IBM ThinkPad Dock I  
to the computer and test it.  
8. If external devices are attached to IBM ThinkPad  
Dock I, such as an audio amplifier, check the device  
by referring to the manual shipped with the device.  
9. If the user did not bring the computer with  
IBM ThinkPad Dock I for service, use a computer that  
works correctly with IBM ThinkPad Dock I.

Checkout Guide  
Use the following procedure as a guide for computer  
problems.  
Note: The diagnostic tests are intended to test only IBM  
products. Non-IBM products, prototype cards, or  
modified options can give false errors and invalid  
system responses.  
Important  
When the Problem Determination Procedure in the  
operation manual that is supplied with the adapter or  
device says “Have the system unit serviced”, this  
means the computer and IBM ThinkPad Dock I.  
1. Obtain the failing symptoms in as much detail as  
possible.  
2. Verify the symptoms by attempting to recreate the  
failure by running the diagnostic test or by repeating  
the same operation.  
Note: To run the diagnostics, refer to “How to Run  
the Diagnostics” on page 557.  
3. Use the following table with the verified symptom to  
determine which page to go to. Search the  
symptoms column and find the description that best  
matches your symptom; then go to the page shown in  
the “Go to” column.  
Symptoms (Verified)

supply is defective, or another component is defective  
causing the power supply to cut off. To verify that the  
power supply is operating correctly, do the following:  
1. Power-off the computer and disconnect the IBM  
ThinkPad Dock I power cord.  
2. Remove all internal and external devices, and the  
computer from the IBM ThinkPad Dock I.  
3. Undock the IBM ThinkPad Dock I.  
4. Remove power supply connector 1 from the riser  
card.  
5. Install jumpers between pins 1 and 10, and pins 3  
and 8 on the main card.

Checking the Installed Devices List  
If a device is installed but the icon appears in a gray shade  
rather than a dark shade on the basic diagnostics screen,  
the device is defective. Reseat the device connectors. If  
the symptom remains, replace the device or the system  
board. If needed, adjust the contrast control to clearly  
distinguish the shades of the icon.  
If a device that is not installed appears in a dark shade (for  
example, FDD-2 appears in a dark shade when NO  
second FDD is installed), do the following:  
1. Replace the first device in the configuration, such as  
an FDD-1, HDD-1, or PCMCIA-1.  
2. If the problem remains, replace the system board.  
The PCMCIA-1, Parallel, and Serial icons are always  
displayed in a dark shade because the icons represent  
subsystems of the system board and not the attachment of  
the devices.  
The FDD-1, HDD-1, or PCMCIA-1 icons represent the first  
drive in the system configuration for each type of device.  
Similarly, the HDD-3, FDD-2, or PCMCIA-2 icons represent  
the second drive, usually attached through a port  
replicator or an expansion unit. The HDD-2 icon  
represents the hard disk drive in the UltraBay.  
Printer  
Test the printer by connecting it to the computer before  
testing it on the IBM ThinkPad Dock I.  
1. Make sure the printer is correctly connected and the  
power is turned on.  
2. Run the printer self-test.  
If the printer self-test does not run correctly, the problem is  
in the printer. Refer to the printer service manual.  
If the printer self-test runs correctly, connect a wrap plug  
on the parallel connector on the rear of IBM ThinkPad  
Dock I and run the advanced diagnostic tests to determine  
the failing FRU.  
If the advanced diagnostic tests (with the wrap plug  
connected) did not detect a failure, replace the printer  
cable.  
If the problem is not corrected, do one of the following:

PC Test Card LED: The green LED on the PC test  
card lights when the PCMCIA test is running. If the LED  
does not go on, check that the card is installed correctly by  
reseating the card. If it still does not light after reseating,  
try using another slot for the test. If the LED still does not  
go on and the test fails, replace the FRU shown in the  
diagnostic error code.  
Errors During the POST: If the POST detects an  
error, a three- to eight-digit error code is displayed.  
Memory Errors: If the POST detects a memory error  
in the first 640KB of system memory, all of the first bank  
memory is de-allocated and the test continues with the  
second 640KB of the second bank memory. If the total  
amount of error free memory becomes less than 2MB, a  
2XX POST error occurs and the system stops. All of the  
remaining memory is used as system memory. When the  
POST memory test has completed, the usable memory  
size is compared with the configuration data and if a  
mismatch is detected, a 2XX error code occurs. The user  
can continue with system operation by pressing Esc, and  
F1 after restart and call for service at a later time.  
The memory sizes that are de-allocated because of the  
POST process is kept by the hibernation or suspend  
functions. To test this memory, it must be re-configured as  
part of the original memory size. The memory  
re-configuring is done by turning power off and on.  
De-allocation support is done only by the POST for  
memory errors. All unrecoverable memory errors that  
occur during normal operation cause an interrupt to the  
operating system.

Symptom-to-FRU Index  
The Symptom-to-FRU Index lists error symptoms and  
possible causes. The most likely cause is listed first.  
Note: Replace the FRUs one at a time in the sequence  
shown in the FRUs of the IBM ThinkPad Dock I  
Sequence of Action column. If a replaced part did  
not resolve the problem, put the original part back  
in the IBM ThinkPad Dock I. Do not replace  
non-defective parts.  
Always begin with “General Preparation” on page 550.  
This index also can be used to help you decide which  
FRUs to have available when servicing the IBM ThinkPad  
Dock I.  
Numeric error codes show the errors detected in the POST  
or system operation. Xs, when included in the error code,  
can be any number.  
FRU codes are used for errors detected by diagnostic  
tests.  
If no error codes are available, use narrative symptoms.  
If the symptom is not listed or you cannot correct the  
problem using this index, go to “Undetermined Problems”  
on page 573.  
If you cannot correct the problem using this index, go to  
“Undetermined Problems” on page 573.  
IMPORTANT:  
1. Before replacing any SCSI device, verify that there  
are no duplicate SCSI ID settings.  
2. Make sure that there are no conflicts of hardware  
settings, such as, interrupt level, memory address,  
DMA channel, and I/O address.  
3. If you have both an error message and an incorrect  
audio response, diagnose the error message first.  
4. If you cannot run the advanced diagnostic tests, but  
did receive a POST error message, diagnose the  
POST error message.  
5. If you did not receive an error message, look for a  
description of your error symptoms in the first part of  
this index.  
6. Check all power supply voltages before you replace  
the main card, riser card, and audio card of the IBM  
ThinkPad Dock I. (See “Power Supply” on  
page 552.)

replacing a FRU does not correct the problem, see the  
device ID or error code from the previous failure. If they  
have changed, the cause might be because the new FRU  
is detective or that the FRU was incorrectly installed.  
Device ID: If an error is detected by the diagnostic  
tests, a three digits device ID is displayed. The device ID  
indicates suspected device.

Undetermined Problems  
Use the following procedure when the diagnostic tests do  
not identify the failing adapter or device.  
Check that all cables, wires, and connectors are connected  
so that they do not cause a short circuit. If any problems  
are found, reconnect or replace them.  
Check the power supply for correct operation (see “Power  
Supply” on page 552). If the power supply is operating  
correctly, return here and continue with the following  
procedures.  
1. Power-off the computer.  
2. Remove or disconnect one at a time the following  
adapters or devices from IBM ThinkPad Dock I. (Do  
not isolate adapters or devices that are known to be  
good.)  
a. Non-IBM devices.  
b. A modem, printer, mouse, external keyboard,  
external display, external diskette drive, numeric  
keypad, or other external devices.  
c. Any adapter.  
Note: Removing an adapter or device may  
cause configuration errors. Ignore error  
code 174.  
d. SCSI device.  
e. Hard disk drive.  
3. Power-on the system and check if the problem has  
changed.  
4. If the symptom remains, repeat Steps 1 through 3  
until you find the failing adapter or device, or until all  
adapters or devices have been removed.  
5. If all adapters or devices have been removed and the  
problem remains, replace the following IBM ThinkPad  
Dock I FRUs one at a time.  
Note: If a replaced part did not resolve the problem,  
put the original part back in the IBM ThinkPad  
Dock I. Do not replace non-defective parts.  
a. Riser card  
b. Main card  
c. IBM ThinkPad Dock I audio card  
If the problem goes away when you remove an adapter,  
but replacing the adapter does not correct the problem,  
replace the main card of IBM ThinkPad Dock I.

PCMCIA-2 devices via a port replicator, suspect an  
over-current problem. Some PCMCIA devices use more  
power; if the maximum usage of each device occurs  
simultaneously, the total current will exceed the limit,  
thereby causing a power shut down. Isolate this problem  
by removing one of the devices, and use the computer  
under the same condition, and see whether a power shut  
down occurs. Do this procedure for all devices then  
determine the cause. Customer purchase of the larger AC  
adapter (50W, optional) is recommended, if it is not yet in  
use.

TrackPoint Checkout  
Ÿ
If the TrackPoint does not work, check the  
configuration. If the configuration of the TrackPoint is  
set to Disabled or Off, change it to Enable or On.  
If the problem remains, continue.  
Note: TrackPoint automatically compensates to  
adjust the pointer sensor. This causes the  
pointer to move slightly on the screen and  
then stop. Pointer movement might occur  
when a slight, steady pressure is applied to  
the TrackPoint pointer when the computer is  
powered-on or running, or when exceeded  
temperature range requires re-adjustment.

If the cursor floats or moves erratically, power-off and

1. Go to the Easy-Setup screen.  
2. Select an item with the pointing stick.  
3. Press either left or right click button.  
4. Verify that both buttons work correctly.  
If the pointing stick or the click button does not work,  
do the following.  
1. Reseat the keyboard cables.  
2. Replace the keyboard.  
3. Replace the interposer card  
(355x, 360x, 750x, 755x).  
4. Replace keyboard control card (720).  
5. Replace the system board.

Do diagnostics fail?  
What, when, where, single, or multiple systems?  
Is the failure repeatable?  
Has this configuration ever worked?  
If it has been working, what changes were made  
prior to it failing?

Important  
To eliminate confusion, identical systems are  
considered identical only if they:  
1. Are the exact machine type and models  
2. Have the same BIOS level  
3. Have the same adapters/attachments in the  
same locations  
4. Have the same address  
jumpers/terminators/cabling  
5. Have the same software versions and levels  
6. Have the same Reference Diskette (version)  
7. Have the same configuration options set in the  
system  
8. Have the same setup for the operation system  
control files  
Comparing the configuration and software set-up  
between “working and non-working” systems will often  
lead to problem resolution.
