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 PC Company
HelpCenter at 800-772-2227 if they need assistance
in obtaining or installing any diskette fixes.
Customers in Canada should call IBM HelpPC at
800-565-3344 for assistance or download
information.
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.
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 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.
When lifting any heavy object:
1. Ensure you can stand safely without slipping.
2. Distribute the weight of the object equally between
your feet.
v
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
v
Do not perform any action that causes hazards to the
customer, or that makes the equipment unsafe.
Before you start the machine, ensure that other service
representatives and the customer’s personnel are not in
a hazardous position.
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.

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
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:
–
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.

Safety information
Observe the special safety precautions when you work
with very high voltages; these instructions are in the
safety sections of maintenance information. Use
extreme care when measuring high voltages.
Regularly inspect and maintain your electrical hand tools
for safe operational condition.
v
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.
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.
v
v
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

Safety information
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 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.
Handling electrostatic
discharge-sensitive devices
Any computer part containing transistors or integrated
circuits (ICs) should be considered sensitive to electrostatic
discharge (ESD.) ESD damage can occur when there is a
difference in charge between objects. Protect against ESD
damage by equalizing the charge so that the machine, the
part, the work mat, and the person handling the part are all
at the same charge.
Notes
1. Use product-specific ESD procedures when they
exceed the requirements noted here.
2. Make sure that the ESD protective devices you
use have been certified (ISO 9000) as fully
effective.
When handling ESD-sensitive parts:
v
Keep the parts in protective packages until they are
inserted into the product.
v
Avoid contact with other people.

Safety information
Wear a grounded wrist strap against your skin to
eliminate static on your body.
Prevent the part from touching your clothing. Most
clothing is insulative and retains a charge even when
you are wearing a wrist strap.
v
v
v
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.
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.

Only certified trained personnel should
service the computer.
Read the entire FRU removal and replacement
page before replacing any FRU.
Use new nylon-coated screws when you
replace FRUs.
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 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.
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.

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 HDP—for the user
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. It 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.
Supervisor password:
A supervisor password (SVP) protects the system
information stored in the IBM BIOS Setup Utility. The SVP
must be entered in order to get access to the IBM BIOS
Setup Utility and make changes to system configuration
settings.
Attention
If the SVP has been forgotten and cannot be made
available to the servicer, there is no service
procedure to reset the password. The systemboard
must be replaced for a scheduled fee.
How to remove the power-on password
To remove a POP that you have forgotten, do the
following:
(A) If no SVP has been set:
1. Turn off the computer.
2. Remove the battery pack.

Power management
To reduce power consumption, the computer has three
power management modes: screen blank, standby, and
hibernation.
Notes
v
v
Screen blank mode is called standby mode in
Windows 95 and Windows NT.
Standby mode is called suspend mode in
Windows 95 and Windows NT.
Screen blank mode
Screen blank mode has three variants, as follows:
1. If you press Fn + F3, or the time set on the “LCD off
timer” in IBM BIOS Setup Utility expires,

v
If the battery indicator blinks orange, indicating that the
battery power is low. (Alternatively, if Hibernate when
battery becomes low has been selected in the “Power
Management Properties” window, the computer goes
into hibernation mode.)
Note for the APM operating system:
Even if you do not set the low-battery alarm, the charge
indicator notifies you when 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.
If you are using the ACPI operating system, only the
low-battery alarm is available.
To cause the computer to return from standby mode and
resume operation, do one of the following:
v
v
Press the Fn key.
Open the LCD cover (only if you are using Windows Me
and you entered standby mode by closing the LCD
cover.)
v
Turn on the power switch.
Also, the computer automatically returns from standby
mode and resumes operation in either of the following
events:
v
The ring indicator (RI) is signaled by a serial device or a
PC Card device (Windows 2000 does not support the
ring indicator (RI) resume by PC Card device.)
The time set on the resume timer elapses. In Windows
98, the Scheduled Tasks setting takes priority over the
Resume on timer selection in the “Power Management
Properties” window.
v
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 Windows NT
If you are using Windows NT in the default format,
NTFS, you cannot create a hibernation file. If you
want to use hibernation mode, you will need to
reinstall Windows NT with FAT format.

Related service information
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
from the docking station 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.

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,

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 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
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.
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

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
You are here because the diagnostic tests did not identify
which adapter or device failed, wrong devices are installed,
a short circuit is suspected, or the system is inoperative.
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
1. Power 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 UltraslimBay
i. PC Cards
4. Power on the computer.
5. Determine whether the problem has changed.
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

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
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 1.62, 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 for each device is displayed. Write
down the serial number of the system unit, designated as
follows:

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.
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
8. When replacing a FRU, use the correct screw as
shown in the procedures.
DANGER
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.
Attention: Before the computer is powered on after FRU
replacement, make sure that 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. 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).
