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 FRU
replacement and service expense:
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 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.

Important service information
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.
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 if the error symptom is listed
in the Symptom-to-FRU Index for the computer you are
servicing.

Safety information
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:
v Observe good housekeeping in the area of the
machines during and after maintenance.
v 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.
v Do not perform any action that causes hazards to the
customer, or that makes the equipment unsafe.
v Before you start the machine, ensure that other service
representatives and the customer’s 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 Keep your toolcase away from walk areas so that other
people will not trip over it.
v 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 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.
v 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.
v After service, reinstall all safety shields, guards, labels,
and ground wires. Replace any safety device that is
worn or defective.
v Reinstall all covers correctly before returning the
machine to the customer.
12ThinkPad TransNote
Safety information
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:
– 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; these instructions are in the
Introduction13
Safety information
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 an electrical accident occurs:
– Use caution; do not become a victim yourself.
– Switch off power.
– Send another person to get medical aid.
Safety inspection guide
The 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 Explosive hazards, such as a damaged CRT face or a
bulging capacitor
v Mechanical hazards, such as loose or missing hardware
14ThinkPad TransNote
Safety information
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. Athird-wire ground connector in good condition.
Use a meter to measure third-wire ground
continuity for 0.1 or less between the external
ground pin and 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.
8. Check that the power-supply cover fasteners (screws
or rivets) have not been removed or tampered with.
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.
Introduction15
Safety information
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 is desirable but
not required to protect against ESD damage.
– Attach the ESD ground clip to any frame ground,
ground braid, or green-wire ground.
– Use an ESD common ground or reference point
when working on a double-insulated or
battery-operated system. You can use coax or
connector-outside shells on these systems.
– Use the round ground-prong of the AC plug on
AC-operated computers.
Grounding requirements
Electrical grounding of the computer is required for
operator safety and correct system function. Proper
grounding of the electrical outlet can be verified by a
certified electrician.

General descriptions
This chapter includes descriptions for any ThinkPad model
that has the PC-Doctor DOS diagnostics program. Some
descriptions might not apply to your particular computer.
Read this first
Before you go to the checkout guide, be sure to read this
section.
Important notes
v Only certified trained personnel should
service the computer.
v Read the entire FRU removal and replacement
page before replacing any FRU.
v Use new nylon-coated screws when you
replace FRUs.
v 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 Replace FRUs only for the correct model.
When you replace a FRU, make sure the model
of the machine and the FRU part number are
correct by referring to the FRU parts list.
v 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.
What to do first:
When you do return a FRU, you must include the following
information in the parts exchange form or parts return form
that you attach to it:
__ 1. Name and phone number of servicer
__ 2. Date of service
__ 3. Date on which the machine failed
__ 4. Date of purchase
__ 5. Failure symptoms, error codes appearing on the
display, and beep symptoms

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. You can enter two HDPs when youselect Master + User.
Attention
If the master HDP has been forgotten, there is no
way to delete it. But you can still get access to the
hard disk if you remember the user HDP. If both
user HDP and master HDP have been forgotten, the
password cannot be removed and the hard disk will
not be accessible.
Supervisor password:
A supervisor password (SVP) protects the system
information stored in the IBM BIOS Setup Utility so that

Related service information
v If the battery indicator blinks orange, indicating that the
battery power is low. (Alternatively, if Hibernate whenbattery becomes low has been selected in the ″Power
Management Properties″ window, the computer goes
into hibernation mode.)
Note: Even if you don’t set the low-battery alarm, the
charge indicator lets you know that the battery is
low, and then the computer enters the power-saving
mode automatically. This default low-battery
behavior is independent of the operating system; so
if you have set the low-battery alarm, the computer
may not do what you specified. It chooses either
your setting or the default setting, whichever is
appropriate.
Any one of the following events causes the computer to
resume operation from standby mode:
v The Fn key is pressed.
v The ring indicator (RI) is signaled by a serial device or a
PC Card device.
v The power switch is turned on.
v In Windows operating system, the Scheduled Tasks
setting has priority over the Resume on timer selection
in the “Power Management Properties” window.
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:
In hibernation mode, the following occurs:

To verify the symptom of a problem, do the following:
1. Power off the computer.
2. Remove the battery pack.
3. Connect the ac adapter.
4. Check that power is supplied when you power on the
computer.
5. Power off the computer.
6. Disconnect the ac adapter and install the charged
battery pack.
7. Check that the battery pack supplies power when you
power on the computer.
If you suspect a power problem, see the appropriate one
of the following power supply checkouts:
v “Checking the ac adapter” on page 29
v “Checking operational charging” on page 29
28ThinkPad TransNote
Checkout guide
v “Checking the battery pack” on page 30
v “Checking the backup battery” on page 31
v “Checking the sub-battery” on page 31
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.″
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:
PinVoltage (V dc)
1+15.5 to +17.0
2Ground
If the voltage is not correct, replace the ac adapter.
If the voltage is acceptable, do the following:
v Replace the system board.
v If the problem persists, go to “Product overview” on
page 35.
Note: Noise from the ac adapter does not always indicate
a defect.
Checking operational charging
To check operational charging, use a discharged battery
pack or a battery pack that has less than 50% of the total
power remaining when installed in the computer.
Perform operational charging. If the battery status indicator
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 the
reinstalled battery pack has not been charged, go to the
next section.
General descriptions29
Checkout guide
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 ensure a maximum battery charge continue charging
the battery for about 30 minutes after the charge indicator
reaches 100%.
To check the status of 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+ 0 to + 16.8
5Ground (−)
3. If the voltage is less than +11.0 V dc, the battery pack
has been discharged.
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.

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.

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. An IBM
ThinkPad computer addresses this problem 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 They 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 141) 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:
v Logic card to plastic
Turn an additional 180 degrees after the screw head
touches the surface of the logic card:
v Torque driver
If you have a torque driver, refer to the “Torque” column
for each step.
50ThinkPad TransNote
FRU replacement notices
v Make sure you use the correct screw. If you have a
torque screwdriver, tighten all screws firmly to the torque
shown in the table. Never use a screw that you
removed. Use a new one. Make sure the screws are
tightened firmly.
Retaining serial numbers
This section includes the following descriptions:
v “Restoring the serial number of the system unit”
v “Retaining the UUID”
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 1.61, and restart the computer.
2. From the main menu, select 1. Set SystemIdentification.
3. Select 2. Read S/N data from EEPROM.
The serial number for each device is displayed. Write
down the serial number of the system unit, designated as
follows:
20: System unit serial number
After you have replaced the system board, restore the
serial number by doing the following:
1. Install the ThinkPad hardware maintenance diskette
version 1.61 and restart the computer.
2. From the main menu, select 1. Set SystemIdentification.
3. Select 1. Add S/N data from EEPROM.
Follow the instructions on the screen.
Note: The serial number of the system unit is written on
the label attached on the bottom of the computer.
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
ThinkPad TransNote51
FRU replacement notices
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 1.61, 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.

Removing and replacing a FRU
Removing and replacing a FRU
This section presents information and drawings for use in
removing and replacing a FRU. Be sure to observe the
following general rules:
1. Do not try to service the 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 50.
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 indicated in the drawings by the numbers
in square callouts.
5. When turning a screw to replace a FRU, turn it in the
direction indicated by the arrow in the drawing.
6. When removing the FRU, move it in the direction
indicated 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 133.
8. When replacing a FRU, use the correct screw as
shown in the procedures.
CAUTION:
Before removing any FRU, power off the computer,
unplug all power cords from electrical outlets, remove
the battery pack, and then disconnect any
interconnecting cables.
CAUTION:
Do not disassemble the battery pack, throw it into fire
or water, or short-circuit it. Dispose of the battery pack
as required by local ordinances or regulations.
Attention: Before the computer is powered on after FRU
replacement, make sure all screws, springs, and other
small parts are in place and are not 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. Establish personal
grounding by touching a ground point with one hand before
touching these units.
You must use an electrostatic discharge (ESD) strap (P/N
6405959) to establish personal grounding.
