Introduction  
Important service information  
Important  
BIOS and device driver fixes are  
customer-installable. The BIOS and device drivers  
are posted on the IBM support site  
Advise customers to contact the IBM Support  
Center at 800-426-7378 (800-IBM-Serv) if they need  
assistance in obtaining or installing any diskette  
fixes.  
Customers in Canada should call IBM Support  
Center at 800-565-3344 for assistance or download  
information.  
Strategy for replacing FRUs  
Before replacing parts  
Make sure that all diskette fixes are installed before  
replacing any FRUs listed in this manual.  
Use the following strategy to prevent unnecessary expense  
for replacing and servicing FRUs:  
v
If you are instructed to replace a FRU but the  
replacement does not correct the problem, reinstall  
the original FRU before you continue.  
v
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 replacing one  
of them does not correct the problem, reinstall that  
board, and then replace the other one.  
v
If an adapter or a device consists of more than one  
FRU, any of the FRUs may be the cause of the error.  
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: The setup configuration on the computer you  
are servicing may have been customized. Running  
Automatic Configuration may alter the settings. Note the  
current configuration settings (using the View Configuration  
option); then, when service has been completed, verify that  
those settings remain in effect.

Important service information  
Strategy for replacing a hard disk drive  
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 may have been changed. Be extremely  
careful during write operations such as copying, saving, or  
formatting. If you select an incorrect drive, data or  
programs can be overwritten.  
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. Whatever causes the  
first error code may also cause false error codes. If no  
error code is displayed, see whether the error symptom is  
listed in the Symptom-to-FRU Index for the computer you  
are servicing.

Safety notice 1  
Before the computer is powered on after FRU  
replacement, make sure all screws, springs, and 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 lordinateur sous tension après  
remplacement dune unité en clientèle, vérifiez que  
tous les ressorts, vis et autres pièces sont bien en  
place et bien fixées. Pour ce faire, secouez lunité et  
assurez-vous quaucun 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 lelaboratore 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 allinterno dellelaboratore. Verificare ciò  
scuotendo lelaboratore 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  
Safety information  
The following section presents safety information with  
which you need to be familiar before you service an IBM  
mobile computer.  
General safety  
Follow these rules to ensure general safety:  
v
v
Observe good housekeeping in the area of the  
machines during and after maintenance.  
When lifting any heavy object:  
1. Make sure that 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  
object that weighs more than 16 kg (35 lb) or that  
you think is too heavy for you.  
v
v
Do not perform any action that causes hazards to the  
customer, or that makes the equipment unsafe.  
Before you start the machine, make sure that other  
service representatives and the customers personnel  
are not in a hazardous position.  
v
Place removed covers and other parts in a safe place,  
away from all personnel, while you are servicing the  
machine.  
v
v
Keep your toolcase 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. Make sure that your sleeves  
are fastened or rolled up above your elbows. If your hair  
is long, fasten it.  
v
v
Insert the ends of your necktie or scarf inside clothing or  
fasten it with a nonconductive clip, about 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.  
v
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.

Safety information  
v
After service, reinstall all safety shields, guards, labels,  
and ground wires. Replace any safety device that is  
worn or defective.  
v
v
Reinstall all covers correctly before returning the  
machine to the customer.  
Fan louvers on the machine help to prevent overheating  
of internal components. Do not obstruct fan louvers or  
cover them with labels or stickers.  
WARNING  
Handling the cord on this product or cords  
associated with accessories sold with this product  
will expose you to lead, a chemical known to the  
State of California to cause cancer, and birth defects  
or other reproductive harm. Wash hands after  
handling.  
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.  
v
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.  
v
v
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  
v
v
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:  
Introduction 17  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Safety information  
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: An electrical shock can occur only when  
there is a complete circuit. 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; Instructions for these  
precautions are in the safety sections of maintenance  
information. Use extreme care when measuring high  
voltages.  
v
Regularly inspect and maintain your electrical hand tools  
for safe operational condition.  
v
v
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.  
v
v
v
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.)  
v
If an electrical accident occurs:  
Use caution; do not become a victim yourself.  
Switch off power.  
Send another person to get medical aid.

Safety information  
Safety inspection guide  
The purpose of this inspection guide is to assist you in  
identifying potentially unsafe conditions. As each machine  
was designed and built, required safety items were  
installed to protect users and service personnel from injury.  
This guide addresses only those items. You should use  
good judgment 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:  
v
Electrical hazards, especially primary power (primary  
voltage on the frame can cause serious or fatal  
electrical shock)  
v
v
Explosive hazards, such as a damaged CRT face or a  
bulging capacitor  
Mechanical hazards, such as loose or missing hardware  
To determine whether there are any potentially unsafe  
conditions, use the following checklist at the beginning of  
every service task. 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 the frame ground.  
b. The power cord should be the type specified in the  
parts list.  
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.  
Introduction 19

Safety information  
8. Check that the power-supply cover fasteners (screws  
or rivets) have not been removed or tampered with.  
Handling devices that are sensitive to  
electrostatic discharge  
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:  
v
Keep the parts in protective packages until they are  
inserted into the product.  
v
v
Avoid contact with other people.  
Wear a grounded wrist strap against your skin to  
eliminate static on your body.  
v
v
v
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 to guard against  
ESD damage is desirable but not necessary.  
Attach the ESD ground clip to any frame ground,  
ground braid, or green-wire ground.  
When working on a double-insulated or  
battery-operated system, use an ESD common  
ground or reference point. You can use coax or  
connector-outside shells on these systems.

Important notes  
v
v
v
v
Only certified trained personnel should  
service the computer.  
Before replacing any FRU, read the entire  
page on removing and replacing FRUs.  
When you replace FRUs, use new  
nylon-coated screws.  
Be extremely careful during such write  
operations as copying, saving, or formatting.  
Drives in the computer that you are servicing  
sequence might have been altered. If you select  
an incorrect drive, data or programs might be  
overwritten.  
v
v
Replace an FRU only with another FRU of the  
correct model. When you replace a FRU, make  
sure that the model of the machine and the FRU  
part number are correct by referring to the FRU  
parts list.  
A FRU should not be replaced because of a  
single, unreproducible failure. Single failures  
can occur for a variety of reasons that have  
nothing to do with a hardware defect, such as  
cosmic radiation, electrostatic discharge, or  
software errors. Consider replacing a FRU only  
when a problem recurs. If you suspect that a  
FRU is defective, clear the error log and run the  
test again. If the error does not recur, do not  
replace the FRU.  
v
Be careful not to replace a nondefective FRU.

Passwords  
As many as three passwords may be needed for any  
ThinkPad computer: the power-on password (POP), the  
hard-disk password (HDP), and the supervisor password  
(SVP).  
If any of these passwords has been set, a prompt for it  
appears on the screen whenever the computer is turned  
on. The computer does not start until the password is  
entered.  
Exception: If only an SVP is installed, the password  
prompt does not appear when the operating  
system is booted.  
Power-on password:  
A power-on password (POP) protects the system from  
being powered on by an unauthorized person. The  
password must be entered before an operating system can  
be booted.  
Hard-disk password:  
There are two hard-disk passwords (HDPs):  
v
v
User HDPfor the user  
Master HDPfor the system administrator, who can use  
it to get access to the hard disk even if the user has  
changed the user HDP  
Note: There are two modes for the HDP: User only and  
Master + User. The Master + User mode requires  
two HDPs; the system administrator enters both in  
the same operation. The system administrator then  
provides the user HDP to the system user.  
Attention: If the user HDP has been forgotten, check  
whether a master HDP has been set. If it has, it can be  
used for access to the hard disk drive. If no master HDP is  
available, IBM does not provide any services to reset  
either the user or the master HDP, or to recover data from  
the hard disk drive. The hard disk drive can be replaced  
for a scheduled fee.

Use the following procedures as a guide in identifying and  
correcting problems with the ThinkPad computer.  
Note: The diagnostic tests are intended to test only IBM  
products. The use of non-IBM products, prototype  
cards, or modified options can lead to false  
indications of errors and invalid system responses.  
1. Identify the failing symptoms in as much detail as  
possible.  
2. Verify the symptoms. Try to re-create the failure by  
running the diagnostic test or by repeating the  
operation.  
Testing the computer  
The ThinkPad computer has a test program called  
PC-Doctor® DOS (hereafter called PC-Doctor.) You can  
detect errors by running the diagnostics test included in  
PC-Doctor. This section is an overview of the procedure.  
For details that depend on model-unique functions, refer to  
For some possible configurations of the computer,  
PC-Doctor might not run correctly. To avoid this problem,  
you need to initialize the computer setup by use of the IBM  
BIOS Setup Utility before you run PC-Doctor. On the IBM  
BIOS Setup Utility screen, press F9, Enter, F10, and then  
Enter.  
Note: When you initialize the computer configuration,  
some devices are disabled, such as the serial port.  
If you test one of these devices, you will need to  
enable it by using PS2.EXE.  
PC-Doctor cannot be used to test a device that is in the  
docking station, even if the computer supports the docking  
station. To test a USB device, connect it to the USB  
connector of the computer.  
Creating the PC-Doctor diagnostics diskette  
To create the PC-Doctor disk from the Access IBM  
Predesktop Area, do as follows:  
1. Enter the IBM Predesktop application by pressing the  
Access IBM button during POST.  
2. When the Access IBM application finishes loading,  
double-click the Create Diagnostic Diskettesicon.  
3. Authenticating the digital signature takes about 15  
seconds; then the ThinkPad computer will reboot into  
PC-DOS.

4. A batch file automatically starts up to prompt you  
through the process of creating diskettes. You are  
notified of how many diskettes you will need.  
a. You are prompted to insert each diskette in  
sequence.  
b. Typically, all you need to do is to press the Enter  
key for the floppy drive; the system then formats  
and creates the diskette.  
c. Each diskette is erased and formatted with the  
PC-Doctor DOS boot image.  
5. Once all the diskettes have been created, the  
ThinkPad computer will reboot. The user is asked to  
remove all diskettes from the drive, or to insert the first  
diskette created if it is desired to run the diagnostics.  
To run the test, do as follows:  
Note: In the following procedure, you can select an item  
not only with the arrow keys, but also with the  
TrackPoint pointer. Instead of pressing Enter, click  
the left button.  
1. Insert the PC-Doctor disk into the diskette drive; then  
power on the computer.

Power system checkout  
To verify a symptom, do the following:  
1. Turn off the computer.  
2. Remove the battery pack.  
3. Connect the ac adapter.  
4. Check that power is supplied when you turn on the  
computer.  
5. Turn off the computer.  
6. Disconnect the ac adapter and install the charged  
battery pack.  
7. Check that the battery pack supplies power when you  
turn on the computer.  
If you suspect a power problem, see the appropriate one  
of the following power supply checkouts:  
v
v
v
v
Checking the ac adapter  
You are here because the computer fails only when the ac  
adapter is used.  
v
If the power problem occurs only when the port  
replicator is used, replace the port replicator.  
v
If the power-on indicator does not turn on, check the  
power cord of the ac adapter for correct continuity and  
installation.  
v
If the computer does not charge during operation, go to  
Checking operational charging.″  
To check the ac adapter, do the following:  
1. Unplug the ac adapter cable from the computer.  
2. Measure the output voltage at the plug of the ac  
adapter cable. See the following figure:  
Pin Voltage (V dc)

3. If the voltage is not correct, replace the ac adapter.  
4. If the voltage is acceptable, do the following:  
v
Replace the system board.  
If the problem persists, go to Product overviewon  
v
Note: Noise from the ac adapter does not always indicate  
a defect.

Checking operational charging  
To check whether the battery charges properly during  
operation, 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  
or icon does not turn on, remove the battery pack and let it  
return to room temperature. Reinstall the battery pack. If  
the charge indicator or icon still does not turn on, replace  
the battery pack.  
If the charge indicator still does not turn on, replace the  
system board. Then reinstall the battery pack. If it is still  
not charged, go to the next section.  
Checking the battery pack  
Battery charging does not start until the Power Meter  
shows that less than 95% of the total power remains;  
under this condition the battery pack can charge to 100%  
of its capacity. This protects the battery pack from being  
overcharged or from having a shortened life.  
To check your battery, move your cursor to the Power  
Meter icon in the icon tray of the Windows taskbar and  
wait for a moment (but do not click), and the percentage of  
battery power remaining is displayed. To get detailed  
information about the battery, double-click the Power Meter  
icon.  
Note: If the battery pack becomes hot, it may not be able  
to charge. Remove it from the computer and leave it  
at room temperature for a while. After it cools down,  
reinstall and recharge it.  
To check the battery pack, do the following:  
1. Power off the computer.  
2. Remove the battery pack and measure the voltage  
between battery terminals 1 (+) and 5 (−). See the  
following figure:  
Terminal Voltage (V dc)  
1
5
+ 0 to + 12.6  
Ground (−)  
1(+)  
2
3
4
5(-)  
3. If the voltage is less than +11.0 V dc, the battery pack  
has been discharged.

Checkout guide  
Note: Recharging will take at least 3 hours, even if the  
indicator does not turn on.  
If the voltage is still less than +11.0 V dc after  
recharging, replace the battery.  
4. If the voltage is more than +11.0 V dc, measure the  
resistance between battery terminals 4 and 5. The  
resistance must be 4 to 30 K .  
If the resistance is not correct, replace the battery  
pack. If the resistance is correct, replace the system  
board.  
Checking the backup battery  
Do the following:  
1. Power off the computer, and unplug the ac adapter  
from it.  
2. Turn the computer upside down.  
3. Remove the battery pack (see 1010 Battery pack for  
4. Remove the backup battery (see Checking the battery  
5. Measure the voltage of the backup battery. See the  
following figure.

configuration as specified in the ThinkPad  
Configuration program. If the TrackPoint is  
disabled, select Automatic to enable it.  
After you use the TrackPoint, the pointer may  
drift on the screen for a short time. This drift  
can occur when a slight, steady pressure is  
applied to the TrackPoint pointer. This symptom  
is not a hardware problem. If the pointer stops

Intermittent problems  
Intermittent system hang problems can be due to a variety  
of causes 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 problem recurs.  
When analyzing an intermittent problem, do the following:  
1. Run the 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  
If the diagnostic tests did not identify the adapter or device  
that has failed, if wrong devices are installed, or if the  
system simply is not operating, follow these procedures to  
isolate the failing FRU (do not isolate FRUs that have no  
defects).  
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 system  
1. Turn off the computer.  
2. Visually check each FRU for damage. Replace any  
damaged FRU.  
3. Remove or disconnect all of the following devices:  
a. Non-IBM devices  
b. Devices attached to the port replicator  
c. Printer, mouse, and other external devices  
d. Battery pack  
e. Hard disk drive  
f. External diskette drive  
g. DIMM  
h. CD-ROM and diskette drive in the Ultrabay  
i. PC Cards  
4. Turn on the computer.  
5. Determine whether the problem has been solved.  
6. If the problem does not recur, 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):  
a. System board  
b. LCD assembly

v
They maintain tight connections.  
They do not easily come loose, even with shock or  
vibration.  
v

Restoring the serial number of the system  
unit  
When the computer was manufactured, the EEPROM on  
the system board was loaded with the serial numbers of  
the system and all major components. These numbers  
need to remain the same throughout the life of the  
computer.  
If you replace the system board, you must restore the  
serial number of the system unit to its original value.  
Before replacing the system board, save the original serial  
number by doing the following:  
1. Install the ThinkPad Hardware Maintenance Diskette  
Version 1.71 or later, and restart the computer.  
2. From the main menu, select 1. Set System  
Identification.  
3. Select 2. Read S/N data from EEPROM.  
The serial number of each device in your computer is  
displayed; the serial number of the system unit is listed as  
follows:  
20: Serial number  
Write down that number.  
Note: The serial number of the system unit is also written  
on the label attached to the bottom of the computer.  
After you have replaced the system board, restore the  
serial number by doing the following:  
1. Install the ThinkPad Hardware Maintenance Diskette  
Version 1.71 or later and restart the computer.  
2. From the main menu, select 1. Set System  
Identification.  
3. Select 1. Add S/N data from EEPROM.  
Follow the instructions on the screen.

Retaining the UUID  
The Universally Unique Identifier (UUID) is a 128-bit  
number uniquely assigned to your computer at production  
and stored in the EEPROM of your system board. The  
algorithm that generates the number is designed to provide  
unique IDs until the year A.D. 3400. No two computers in  
the world have the same number.  
When you replace the system board, you must set the  
UUID on the new system board as follows:  
1. Install the ThinkPad Hardware Maintenance Diskette  
Version 1.71 or later, and restart the computer.  
2. From the main menu, select 4. Assign UUID.  
A new UUID is created and written. If a valid UUID  
already exists, it is not overwritten.  
Reading or writing the ECA information  
Information on Engineering Change Announcements (ECA)  
are stored in the EEPROM of the system board. The  
electronic storage of this information simplifies the  
procedure to check if the ECA has been previously applied  
to a machine. The machine does not need to be  
disassembled to check for the ECA application.  
To check what ECAs have been previously applied to the  
machine, use the ECA Information Read/Write function on  
the ThinkPad Hardware Maintenance Diskette Version 1.71  
or later.  
1. Insert the ThinkPad Hardware Maintenance Diskette  
Version 1.71 or later, and restart the computer.  
2. From the main menu, select 6. Set ECA Information.  
3. To read ECA information, select 2. Read ECA/rework  
number from EEPROM and follow the instruction.  
4. To read box build date, select 5. Read box build date  
from EEPROM, and follow the instruction on the  
screen.  
After an ECA has been applied to the machine, the  
EEPROM must be updated to reflect the ECA's  
application. Use the ThinkPad Hardware Maintenance  
Diskette Version 1.71 or later to update the EEPROM.  
Note: Only the ECA number is stored in the EEPROM.  
The machine type of the ECA is assumed be the  
same as the machine type of the machine that had  
the ECA applied to it.  
1. Insert the ThinkPad Hardware Maintenance Diskette  
Version 1.71 or later, and restart the computer.  
2. From the main menu, select 6. Set ECA Information.

FRU replacement notices  
3. To write ECA information, select 1. Write ECA/rework  
number from EEPROM, and follow the instruction.  
4. To write box build date, select 4. Write box build date  
from EEPROM, and follow the instruction on the  
screen.  
If the system board is being replaced, try to read the ECA  
information from the old system board and transfer the  
information to the new system. If the system board is  
inoperable, this will not be possible.

Removing and replacing a FRU  
Removing and replacing a FRU  
This section presents directions and drawings for use in  
removing and replacing a FRU. Be sure to observe the  
following general rules:  
1. Do not try to service any computer unless you have  
been trained and certified. An untrained person runs  
the risk of damaging parts.  
2. Before replacing any FRU, review FRU replacement  
3. Begin by removing any FRUs that have to be removed  
before the failing FRU. Any such FRUs are listed at the  
top of the page. Remove them in the order in which  
they are listed.  
4. Follow the correct sequence in the steps for removing  
the FRU, as given in the drawings by the numbers in  
square callouts.  
5. When turning a screw to replace a FRU, turn it in the  
direction as given by the arrow in the drawing.  
6. When removing the FRU, move it in the direction as  
given by the arrow in the drawing.  
7. To put the new FRU in place, reverse the removal  
procedure and follow any notes that pertain to  
replacement. For information about connecting and  
arranging internal cables, see Locationson page 186.  
8. When replacing a FRU, use the correct screw as  
shown in the procedures.  
DANGER  
Before removing any FRU, turn off the computer,  
unplug all power cords from electrical outlets,  
remove the battery pack, and then disconnect any  
interconnecting cables.  
Attention: After replacing a FRU, do not turn on the  
computer until you have made sure that all screws,  
springs, and other small parts are in place and none are  
loose inside the computer. Verify this by shaking the  
computer gently and listening for rattling sounds. Metallic  
parts or metal flakes can cause electrical short circuits.  
Attention: The system board is sensitive to, and can be  
damaged by, electrostatic discharge. Before touching it,  
establish personal grounding by touching a ground point  
with one hand or by using an electrostatic discharge (ESD)  
strap (P/N 6405959).

Important  
When handling the system board in ThinkPad T41  
series, bear the following in mind.  
v
The system board of the ThinkPad T41 series  
has an accelerometer, which can be broken by  
applying several thousands of G-forces.  
Note: Dropping a system board from a height of  
as little as 6 inches so that it falls flat on a  
hard bench can subject the accelerometer  
to as much as 6,000 Gs of shock.  
v
v
Be careful not to drop the system board on a  
bench top that has a hard surface, such as metal,  
wood, or composite.  
If a system board is dropped, you must test it,  
using PC-Doctor DOS, to make sure that the IBM  
HDD Active Protection still functions (see below).  
Note: If the test shows that IBM HDD Active  
Protection is not functioning, be sure to  
document the drop in any reject report,  
and replace the system board.  
v
v
Avoid rough handling of any kind.  
At every point in the process, be sure not to drop  
or stack the system board.  
v
If you put a system board down, be sure to put it  
only on a padded surface such as an ESD mat or  
conductive corrugated material.  
After replacing the system board, run PC-Doctor  
DOS to make sure that IBM HDD Active Protection  
still functions. The procedure is as follows:  
1. Place the computer on a horizontal surface.  
2. Run Diagnostics --> Other Devices --> IBM  
HDD Active Protection Test.  
Attention: Do not apply physical shock to the  
computer while the test is running.
