Introduction  
Important Service Information  
Important  
Diskette fixes are customer installable. The diskette  
fixes are located on the PC Company Bulletin Board  
Service (BBS). The direct phone line for modem con-  
nection is 919-557-0001 or tieline 255-0001.  
Advise customers to contact the PC Company  
HelpCenter at 800-772-2227 if they need assistance in  
obtaining or installing any diskette fixes.  
Customers in Canada should call IBM HelpPC at  
800-565-3344 for assistance or download information.

Winnipeg 204-934-2735  
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 ser-  
vicing. 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.  
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 over-written 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 high-  
lighted 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 informa-  
tion in an eight-digit error message.  
POST  
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 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.  
Ÿ
Ÿ
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
Place removed covers and other parts in a safe  
place, away from all personnel, while you are ser-  
vicing 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 conduc-  
tors.  
Ÿ
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.  
After service, reinstall all safety shields, guards,  
labels, and ground wires. Replace any safety device  
that is worn or defective.  
Introduction 11

Ÿ
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 elec-  
trical currents. Many customers have, near their equip-  
ment, 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 elec-  
trical 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 accesso-  
ries 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. Regu-  
larly 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 your-  
self.  
–
–
Switch off power.  
Send another person to get medical aid.  
Safety Inspection Guide  
The intent of this inspection guide is to assist you in identi-  
fying 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. Con-  
sider these conditions and the safety hazards they present:  
Introduction 13  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Ÿ
Electrical hazards, especially primary power (primary  
voltage on the frame can cause serious or fatal elec-  
trical shock).  
Ÿ
Ÿ
Explosive hazards, such as a damaged CRT face or  
bulging capacitor.  
Mechanical hazards, such as loose or missing hard-  
ware.  
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 conti-  
nuity 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 condi-  
tions, 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 cir-  
cuits ( 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.  
14 ThinkPad i Series 1400 HMM  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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 oper-  
ator safety and correct system function. Proper grounding  
of the electrical outlet can be verified by a certified  
electrician.

Read This First  
Before you go to the check procedures, be sure to read  
this section.  
Important Notes  
Ÿ
Ÿ
Ÿ
Only certified trained personnel should service  
the computer.  
Read the 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 could be overwritten.  
Ÿ
Ÿ
Ensure that you replace FRUs with the appro-  
priate model. When you replace the FRU, make  
sure that 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 failure can  
occur for a variety of reasons that have nothing  
to do with a hardware defect, such as: cosmic  
radiation, electrostatic discharge, or software  
error. FRU replacement should be considered  
only when a recurring problem exists. In this  
case, clear the error log and run the test again.  
Do not replace FRUs if log errors do not reap-  
pear.  
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 the other false error codes being  
displayed.  
How to Diagnose Mulitple 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 exhanging 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 apperaing 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 to the warranty by  
referring to the following:  
Note for Warranty: Durign the warranty period, the cus-  
tomer may be responsible for repair costs if the computer  
damage was caused by misuse, accident, modification,

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 pointer while the  
computer is powered on or while the system is running, or  
when readjustment 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. Boot from the diagnostics diskette and start the PQA  
program (please refer to “Running the PQA Diagnos-  
tics Program” on page 49).

Symptom-to-FRU Index  
The Symptom-to-FRU Index lists the symptoms and errors  
and the possible causes. The most likely cause is listed  
first.  
Note: Perform the FRU replacement or actions in the  
sequence shown in the FRU/Action columns. If a  
FRU does not solve the problem, put the original  
part back in the computer. Do not replace a non-  
defective FRU.  
This index can also be used to help you decide which  
FRUs should be available when servicing a computer.  
Numeric error codes show the errors detected in POST or  
system operation (runtime). In the following error codes, X  
can be any number.  
If no codes are available, use narrative symptoms.  
If the symptom, is not listed, go to “Undetermined  
Problems” on page 45.  
Note: For any IBM device not supported by the diagnostic  
codes in this ThinkPad computer, see the manual

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, electronic discharge, or  
software errors. FRU replacement should only be consid-  
ered when a recurring problem exists.  
When analyzing the intermittent problem, do the following:  
1. Run the diagnostic test for the System board at least  
10 times.  
2. If no error is detected, do not replace any FRUs.  
3. If any error is detected, replace the FRU. Rerun the  
test to verify that there are no more errors.  
Undetermined Problems  
The diagnostic tests did not identify which adapter or  
device failed, which installed devices are incorrect, whether  
a short circuit is suspected, or whether the system is inop-  
erative. Follow the procedures below to isolate the failing  
FRU.  
Verify that the power supply being used at the time of the  
failure is operating correctly.  
1. Power off the computer.  
2. Check the cables, wires, and connectors for short cir-  
cuits 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:  
Ÿ
Ÿ
Non-IBM devices  
Printer, external mouse & keyboard, and other  
external devices  
Ÿ
Ÿ
Ÿ
Ÿ
Battery pack  
Hard disk drive  
Diskette drive/CD-ROM drive  
PC Card (PCMCIA)  
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.

Utility Program Diskette  
The Utility Program Diskette provides the three following  
functions:  
Ÿ
Ÿ
Ÿ
“Setting the Inverter ID”  
“Setting the Thermal Sensor”  
“Writing the VPD Data” on page 55  
Setting the Inverter ID: There is an EEPROM in  
the inverter, which store its supported LCD type and ID  
code. If you replace the LCD with one of a different brand,  
the ID information in the inverter EEPROM should be  
updated.  
Follow the steps below to set the LCD inverter ID:  
1. Boot from the Utility Program Diskette.  
2. Select Panel ID Diagnostic from PC DOS 7.0 Startup  
Menu.  
3. Follow the instructions on the screen to read the  
current ID Code or to set a new inverter ID code.  
Note: When you set a new inverter ID and the new  
LCD is not yet enabled (to function), connect  
an external CRT to see the program execution  
process.  
Attention: Make sure that the new ID code you  
choose corresponds to the LCD brand and type. If  
you write a wrong ID into the inverter, just reboot and  
re-execute the program and input the correct ID code.  
4. Restart the computer — the new LCD should work  
normally.  
Note: If the LCD has no display after changing the ID  
code, make sure you write the correct ID code or  
try reconnecting the LCD FPC cable connectors.  
Setting the Thermal Sensor: The system is  
equipped with sensors to protect against system over-  
heating. By setting the system and processor thermal  
thresholds, the system can turn on the cooling Fan ASM or  
shut down automatically when the temperature reaches the  
defined threshold parameters.  
System experiencing frequent auto sensor shutdown may  
need to reset the thermal sensor threshold.  
Follow the steps below to set the thermal threshold:

1. Boot from the Utility Program Diskette.  
2. Select Thermal Sensor Utility from PC DOS 7.0  
Startup menu.  
3. Follow the instructions on the screen to set the  
thresholds.  
Writing the VPD Data: The EEPROM on the  
System board contains the vital product data (VPD) — that  
is, a system unit serial number and a System board serial  
number. When you replace the System board, restore the  
system unit serial number using the VPD Data Utility. The  
serial number label is attached to the computer.

Read This First  
Before you go to the check procedures, be sure to read  
this section.  
Important Notes  
Ÿ
Ÿ
Ÿ
Only certified trained personnel should service  
the computer.  
Read the 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 could be overwritten.  
Ÿ
Ÿ
Ensure that you replace FRUs with the appro-  
priate model. When you replace the FRU, make  
sure that 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 failure can  
occur for a variety of reasons that have nothing  
to do with a hardware defect, such as: cosmic  
radiation, electrostatic discharge, or software  
error. FRU replacement should be considered  
only when a recurring problem exists. In this  
case, clear the error log and run the test again.  
Do not replace FRUs if log errors do not reap-  
pear.  
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 the other false error codes being  
displayed.  
How to Diagnose Mulitple 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 exhanging 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.  
106 ThinkPad i Series 1400 HMM

2. Date of service.  
3. Date when part failed.  
4. Date of purchase.  
5. Failure symptoms, error codes apperaing 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 to the warranty by  
referring to the following:

Symptom-to-FRU Index  
The Symptom-to-FRU Index lists the symptoms and errors  
and the possible causes. The most likely cause is listed  
first.  
Note: Perform the FRU replacement or actions in the  
sequence shown in the FRU/Action columns. If a  
FRU does not solve the problem, put the original  
part back in the computer. Do not replace a non-  
defective FRU.  
This index can also be used to help you decide which  
FRUs should be available when servicing a computer.  
Numeric error codes show the errors detected in POST or  
system operation (runtime). In the following error codes, X  
can be any number.  
If no codes are available, use narrative symptoms.  
If the symptom, is not listed, go to “Undetermined  
Problems” on page 131.  
Note: For any IBM device not supported by the diagnostic  
codes in this ThinkPad computer, see the manual

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, electronic discharge, or  
software errors. FRU replacement should only be consid-  
ered when a recurring problem exists.  
When analyzing the intermittent problem, do the following:  
1. Run the diagnostic test for the system board at least  
10 times.  
2. If no error is detected, do not replace any FRUs.  
3. If any error is detected, replace the FRU. Rerun the  
test to verify that there are no more errors.  
Undetermined Problems  
The diagnostic tests did not identify which adapter or  
device failed, which installed devices are incorrect, whether  
a short circuit is suspected, or whether the system is inop-  
erative. Follow the procedures below to isolate the failing  
FRU.  
Verify that the power supply being used at the time of the  
failure is operating correctly.  
1. Power off the computer.  
2. Check the cables, wires, and connectors for short cir-  
cuits 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:  
Ÿ
Ÿ
Non-IBM devices  
Printer, external mouse & keyboard, and other  
external devices  
Ÿ
Ÿ
Ÿ
Ÿ
Battery pack  
Hard disk drive  
Diskette drive/CD-ROM/DVD-ROM drive  
PC Card (PCMCIA)  
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.

5. Press Enter and follow the instructions on the screen.  
Setting the LCD Panel ID: There is an EEPROM  
in the inverter, which store its supported LCD type and ID  
code. If you replace the LCD with one of a different brand,  
the ID information in the inverter EEPROM should be  
updated.  
Follow the steps below to set the LCD inverter ID:  
1. Boot from the Maintenance Program Diskette.  
2. Select Panel ID Diagnostic from PC DOS 7.0 Startup  
Menu.  
3. Follow the instructions on the screen to read the  
current ID Code or to set a new inverter ID code.  
Note: When you set a new inverter ID and the new  
LCD is not yet enabled (to function), connect  
an external CRT to see the program execution  
process.  
Attention: Make sure that the new ID code you  
choose corresponds to the LCD brand and type. If  
you write a wrong ID into the inverter, just reboot and  
re-execute the program and input the correct ID code.  
4. Restart the computer — the new LCD should work  
normally.

Note: If the LCD has no display after changing the ID  
code, make sure you write the correct ID code or  
try reconnecting the LCD FPC cable connectors.  
Setting the Thermal Sensor: The system is  
equipped with sensors to protect against system over-  
heating. By setting the system and processor thermal  
thresholds, the system can turn on the cooling Fan ASM or  
shut down automatically when the temperature reaches the  
defined threshold parameters.  
System experiencing frequent auto sensor shutdown may  
need to reset the thermal sensor threshold.  
Follow the steps below to set the thermal threshold:  
1. Boot from the Maintenance Program Diskette.  
2. Select Thermal Sensor Utility from PC DOS 7.0  
Startup menu.  
3. Follow the instructions on the screen to set the  
thresholds.  
Writing the VPD Data: The EEPROM on the  
system board contains the vital product data (VPD) — that  
is, a system unit serial number and a system board serial  
number. When you replace the system board, restore the  
system unit serial number using the VPD Data Utility. The  
serial number label is attached to the computer.
