Introduction
Important service information
Important
BIOS and device driver fixes are
customer-installable. The BIOS and device drivers
are posted on the customer support site
http://www.lenovo.com/support
Advise customers to contact the Customer Support
Center at 800-426-7378 if they need assistance in
obtaining or installing any diskette fixes.
Customers in Canada should call the Customer
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 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

DANGER
Though the main batteries have low voltage, a
shorted or grounded battery can produce enough
current to burn personnel or combustible materials.
Bien que le voltage des batteries principales soit
peu élevé, le court-circuit ou la mise à la masse
d’une batterie peut produire suffisamment de
courant pour brûler des matériaux combustibles ou
causer des brûlures corporelles graves.
Obwohl Hauptbatterien eine niedrige Spannung
haben, können sie doch bei Kurzschluß oder
Erdung genug Strom abgeben, um brennbare
Materialien zu entzünden oder Verletzungen bei
Personen hervorzurufen.
Sebbene le batterie di alimentazione siano a basso
voltaggio, una batteria in corto circuito o a massa
può fornire corrente sufficiente da bruciare
materiali combustibili o provocare ustioni ai tecnici
di manutenzione.

Safety information
Safety information
The following section presents safety information with
which you need to be familiar before you service a
ThinkPad computer.
General safety
Follow these rules to ensure general safety:
v Observe good housekeeping in the area of the
machines during and after maintenance.
v 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.

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 Do not work alone under hazardous conditions or near
equipment that has hazardous voltages.
v Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
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.
v If you need to work on a machine that has exposed
electrical circuits, observe the following precautions:
Introduction
17
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 Do not use worn or broken tools and testers.
v Never assume that power has been disconnected from
a circuit. First, check that it has been powered off.
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.
v 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.
v 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

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-ThinkPad 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 Explosive hazards, such as a damaged CRT face or a
bulging capacitor
v 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-ThinkPad alterations. Use
good judgment as to the safety of any non-ThinkPad
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 Avoid contact with other people.
v Wear a grounded wrist strap against your skin to
eliminate static on your body.
v Prevent the part from touching your clothing. Most
clothing is insulative and retains a charge even when
you are wearing a wrist strap.
v 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.
v 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.
20
T40/T40p, T41/T41p, T42/T42p
Safety information
– 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.

(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 User HDP—for the user
v Master HDP—for 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, neither Lenovo nor Lenovo authorized servicers
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.

Note: The computer does not accept any input
immediately after it enters standby mode. Wait a
few seconds before taking any action to reenter
operation mode.
Hibernation mode
Note for OS/2
If you are using OS/2 in the default format, HPFS,
you cannot create a hibernation file. If you want to
use hibernation mode, you will need to reinstall
OS/2 with FAT format.
In hibernation mode, the following occurs:
v The system status, RAM, VRAM, and setup data are
stored on the hard disk.
v The system is powered off.
Note: If the computer enters the hibernation mode while it
is docked to the docking station, do not undock it
before resuming normal operation. If you do undock
it and then try to resume normal operation, you will
get an error message, and you will have to restart
the system.
To cause the computer to enter hibernation mode, do any
of the following:
v Press the Fn+F12 keys.
General descriptions

ThinkPad products. The use of non-ThinkPad
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 for 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
“Product overview” on page 45.
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
BIOS Setup Utility before you run PC-Doctor. On the 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 Configuration utility for DOS. The
utility is available on the following Web site:
http://www.lenovo.com/support
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 Predesktop application by pressing the
Access IBM button during POST.
2. When the Access IBM application finishes loading,
double-click the “Create Diagnostic Diskettes” icon.

Checkout guide
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 for 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.
If the computer cannot be powered on, go to “Power
system checkout” on page 39, and check the power
sources.
If an error code appears, go to “Symptom-to-FRU
index” on page 58.
On the first screen, select the model and press Enter.
Follow the instructions on the screen.
2. The main panel of PC-Doctor appears.
3. Select Diagnostics with the arrow keys, and press
Enter.
A pull-down menu appears. (Its exact form depends on
the model.)
Note: PC-Doctor menu does not mean the formal
support device list. Some unsupported device
names may appear in the PC-Doctor menu.

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:
4
3
2
1(+)
Terminal
Voltage (V dc)
1
+ 0 to + 12.6
5

3. If the voltage is less than +11.0 V dc, the battery pack
has been discharged.

T40/T40p, T41/T41p, T42/T42p
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
14.1-in. LCD models” on page 71).
4. Remove the backup battery (see “Checking the battery
pack” on page 40).
5. Measure the voltage of the backup battery. See the
following figure.

This index can also help you determine, during regular
servicing, what FRUs are likely to need to be replaced
next.
A numeric error is displayed for each error detected in
POST or system operation. In the displays, n can be any
number.
If no numeric code is displayed, check the narrative
descriptions of symptoms. If the symptom is not described

LCD-related symptoms
Important
The TFT LCD for the notebook computer contains
many thin-film transistors (TFTs). The presence of a
small number of dots that are missing, discolored, or
always lighted 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:
v XGA: 8 or more bright dots, 8 or more dark dots,
or a total of 9 or more bright and dark dots.
v SXGA+: 11 or more bright dots, 13 or more dark
dots, or a total of 16 or more bright and dark
dots.
v UXGA: 11 or more bright dots, 16 or more dark
dots, or a total of 16 or more bright and dark
dots.
Note: A bright dot means a pixel is always on
(white or color.) A dark dot means a pixel is
always off (black color.)

Symptom-to-FRU index
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
checkout” on page 39.)
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-ThinkPad 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

FRU replacement notices
FRU replacement notices
This section contains notices related to removing and
replacing parts. Read this section carefully before replacing
any FRU.
Screw notices
Loose screws can cause a reliability problem. In the
ThinkPad computer, this problem is addressed with special
nylon-coated screws that have the following characteristics:
v They maintain tight connections.
v They do not easily come loose, even with shock or
vibration.
v They are harder to tighten.
v Each one should be used only once.
Do the following when you service this machine:
v Keep the screw kit (for the P/N, see “Miscellaneous
parts” on page 243) in your tool bag.
v Always use new screws.
v Use a torque screwdriver if you have one.
Tighten screws as follows:
v Plastic to plastic
Turn an additional 90 degrees after the screw head
touches the surface of the plastic part:
90 degrees more
(Cross-section)
v Logic card to plastic
Turn an additional 180 degrees after the screw head
touches the surface of the logic card:
180 degrees more
(Cross-section)
v Torque driver
If you have a torque driver, refer to the “Torque” column
for each step.

Retaining serial numbers
This section includes the following descriptions:
v “Restoring the serial number of the system unit”
v “Retaining the UUID” on page 68
v “Reading or writing the ECA information” on page 68
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 1.73 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:
v 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 1.73 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.

FRU replacement notices
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 1.73 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 1.73
or later.
1. Insert the ThinkPad Hardware Maintenance Diskette
Version 1.73 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 1.73 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 1.73 or later, and restart the computer.
2. From the main menu, select 6. Set ECA Information.

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
notices” on page 66.
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 “Locations” on 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).

Removing and replacing a FRU
Important notice for handling the system board in
ThinkPad T40 series:
There are two types of system board FRU for the
ThinkPad T40 series, as follows:
v System board with the security chip (bottom view)
Note: The security chip a is embedded on the
underside of the system board.
a
ThinkPad T40/T40p, T41/T41p, T42/T42p Series
137
Removing and replacing a FRU
v System board without the security chip (bottom view)
Begin by checking the FRU number of the system board,
and be sure to use the correct system board for the
computer. For the FRU numbers, see “Parts list” on page
190.
Important
If the ThinkPad computer you are servicing has a
security chip, bear the following in mind:
v Do not remove the security chip from the
system board. If the security chip is removed by
accident, reinstall it on the system board
immediately. Make sure that it is firmly fixed on
the system board and does not move easily.
v The security chip cannot be used with any other
system board.
v The system board cannot be used with any other
security chip.
v The system board cannot be used without the
security chip.
v If you return a defective system board, you must
check whether the security chip is embedded. If it
is not, the board may not be covered under
warranty.

Removing and replacing a FRU
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 G’s of shock.
v Be careful not to drop the system board on a
bench top that has a hard surface, such as metal,
wood, or composite.
v If a system board is dropped, you must test it,
using PC-Doctor for DOS, to make sure that the
HDD Active Protection still functions (see below).
Note: If the test shows that HDD Active
Protection is not functioning, be sure to
document the drop in any reject report,
and replace the system board.
v Avoid rough handling of any kind.
v 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 for
DOS to make sure that HDD Active Protection still
functions. The procedure is as follows:
1. Place the computer on a horizontal surface.
2. Run Diagnostics --> Other Devices --> HDD
Active Protection Test.
Attention: Do not apply physical shock to the
computer while the test is running.

Note for sticking a label kit on the base cover
New base cover FRU is shipped with several kinds
of label kit. When you replace the base cover, you
need to stick a homologation label a which has
the same part no. with the label on the old base
cover (defective FRU) on the new base cover.
In some models, you also need to stick one or two
FCC labels b. Check the old base cover and if
there is one or two FCC labels on it, find the same

Removing and replacing a FRU
Important
When handling the system board in ThinkPad T42
series, bear the following in mind.
v The system board of the ThinkPad T42 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 G’s of shock.
v Be careful not to drop the system board on a
bench top that has a hard surface, such as metal,
wood, or composite.
v If a system board is dropped, you must test it,
using PC-Doctor for DOS, to make sure that the
HDD Active Protection still functions (see below).
Note: If the test shows that HDD Active
Protection is not functioning, be sure to
document the drop in any reject report,
and replace the system board.
v Avoid rough handling of any kind.
v 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 for
DOS to make sure that HDD Active Protection still
functions. The procedure is as follows:
1. Place the computer on a horizontal surface.
2. Run Diagnostics --> Other Devices --> HDD
Active Protection Test.
Attention: Do not apply physical shock to the
computer while the test is running.
