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

http://www.ibm.com/pc/support

Advise customers to contact the PC Company
HelpCenter at 800-772-2227 if they need assistance

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 expense
for replacing and servicing FRUs:

you are instructed to replace a FRU but the
replacement does not correct the problem, reinstall
the original FRU before you continue.

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

them does not correct the problem, reinstall that

board, and then replace the other one.

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
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 l’elaboratore 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 all’interno dell’elaboratore. Verificare ciò
scuotendo l’elaboratore 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

encuentran sueltas dentro del sistema.
Compruébelo agitando el sistema y escuchando los
posibles ruidos que provocarían. Las piezas metálicas
pueden causar cortocircuitos eléctricos.

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

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

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:

Observe good housekeeping in the area of the
machines during and after maintenance.

When lifting any heavy object:

Make sure that you can stand safely without
slipping.

Distribute the weight of the object equally between
your feet.

Use a slow lifting force. Never move suddenly or
twist when you attempt to lift.

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

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 customer’s personnel
are not in a hazardous position.

Place removed covers and other parts in a safe place,
away from all personnel, while you are servicing the
machine.

Keep your toolcase away from walk areas so that other
people will not trip over it.

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

long, fasten it.

Insert the ends of your necktie or scarf inside clothing or
fasten it with a nonconductive clip, about 8 centimeters

inches) from the end.

not wear jewelry, chains, metal-frame eyeglasses, or
metal fasteners for your clothing.

Attention: Metal objects are good electrical

conductors.

Wear safety glasses when you are hammering, drilling,
soldering, cutting wire, attaching springs, using solvents,

working in any other conditions that might be

hazardous to your eyes.

After service, reinstall all safety shields, guards, labels,
and ground wires. Replace any safety device that is
worn or defective.

Reinstall all covers correctly before returning the
machine to the customer.

Fan louvers on the machine help to prevent overheating

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

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.

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.

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

Before you start to work on the machine, unplug the

v

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.

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.

Regularly inspect and maintain your electrical hand tools
for safe operational condition.

not use worn or broken tools and testers.

Never assume that power has been disconnected from

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.

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.

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

similar units. (This practice ensures correct

and
grounding of the units.)

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.

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:

Electrical hazards, especially primary power (primary
voltage on the frame can cause serious or fatal
electrical shock)

Explosive hazards, such as a damaged CRT face or a
bulging capacitor

Mechanical hazards, such as loose or missing hardware

determine whether there are any potentially unsafe

To
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:

Check exterior covers for damage (loose, broken, or
sharp edges).

Power off the computer. Disconnect the power cord.

Check the power cord for:

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.

The power cord should be the type specified in the
parts list.

Insulation must not be frayed or worn.

Remove the cover.

4.

Check for any obvious non-IBM alterations. Use good
judgment as to the safety of any non-IBM alterations.

Check inside the unit for any obvious unsafe
conditions, such as metal filings, contamination, water

other liquids, or signs of fire or smoke damage.

Check for worn, frayed, or pinched cables.

Check that the power-supply cover fasteners (screws

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

the same charge.

Notes

Use product-specific ESD procedures when they
exceed the requirements noted here.
Make sure that the ESD protective devices you
use have been certified (ISO 9000) as fully
effective.

When handling ESD-sensitive parts:

Keep the parts in protective packages until they are
inserted into the product.

Avoid contact with other people.

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.

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,

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.

2672, 2673, 2884, 2885, 2890, 2891

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.

Drives in the computer that you are servicing
sequence might have been altered. If you select

incorrect drive, data or programs might be

overwritten.

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.

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.

Passwords

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).

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:

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

booted.

Hard-disk password:

There are two hard-disk passwords (HDPs):

User HDP—for the user

Master HDP—for the system administrator, who can use

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.

Identify the failing symptoms in as much detail as
possible.

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
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 IBM
BIOS Setup Utility before you run PC-Doctor. On the IBM
BIOS Setup Utility screen, press F9, Enter, F10, and then
Enter.

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. To test the Ultrabay device,
install it in the Ultrabay Plus slot of the computer.

Checking operational charging

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

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.

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%

its capacity. This protects the battery pack from being

overcharged or from having a shortened life.

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

charge. Remove it from the computer and leave it
room temperature for a while. After it cools down,

reinstall and recharge it.

check the battery pack, do the following:

Power off the computer.
Remove the battery pack and measure the voltage
between battery terminals 1 (+) and 5 (−). See the
following figure:

and errors and their possible causes. The most likely
cause is listed first, in boldface type.

Note: Do the FRU replacement or other actions in the

sequence shown in the column headed “FRU or
action, in sequence.” If replacing a FRU does not
solve the problem, put the original part back in the
computer. Do not replace a nondefective FRU.

This index can also help you determine, during regular
servicing, what FRUs are likely to need to be replaced
next.

numeric error is displayed for each error detected in
POST or system operation. In the displays, n can be any
number.

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:

XGA: 8 or more bright dots, 8 or more dark dots,

total of 9 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 or error

Intermittent problems

Intermittent system hang problems can be due to a variety

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:

Run the diagnostic test for the system board in loop
mode at least 10 times.

error is detected, do not replace any FRUs.

any error is detected, replace the FRU shown by the
FRU code. Rerun the test to verify that no more errors
exist.

Undetermined problems

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 40.)

Turn off the computer.
Visually check each FRU for damage. Replace any
damaged FRU.
Remove or disconnect all of the following devices:

Non-IBM devices
Devices attached to the port replicator
Printer, mouse, and other external devices
Battery pack
Hard disk drive

External diskette drive

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 IBM
ThinkPad computer, this problem is addressed with special
nylon-coated screws that have the following characteristics:

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

Retaining serial numbers

This section includes the following descriptions:

“Restoring the serial number of the system unit”
“Retaining the UUID” on page 68
“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.

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:

Install the ThinkPad Hardware Maintenance Diskette
Version 1.70, and restart the computer.

From the main menu, select 1. Set System
Identification.

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

the label attached to the bottom of the computer.

After you have replaced the system board, restore the
serial number by doing the following:

Install the ThinkPad Hardware Maintenance Diskette
Version 1.70 and restart the computer.

From the main menu, select 1. Set System
Identification.

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:

Install the ThinkPad Hardware Maintenance Diskette
Version 1.70, and restart the computer.

From the main menu, select 4. Assign UUID.

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

machine. The machine does not need to be

disassembled to check for the ECA application.

check what ECAs have been previously applied to the
machine, use the ECA Information Read/Write function on
the ThinkPad Hardware Maintenance Diskette Version

1.70.

Insert the ThinkPad Hardware Maintenance Diskette
Version 1.70, and restart the computer.

From the main menu, select 6. Set ECA Information.

read ECA information, select 2. Read ECA/rework

number from EEPROM and follow the instruction.

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 1.70 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.

Insert the ThinkPad Hardware Maintenance Diskette
Version 1.70, and restart the computer.

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:

not try to service any computer unless you have
been trained and certified. An untrained person runs
the risk of damaging parts.

Before replacing any FRU, review “FRU replacement
notices” on page 66.

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.

Follow the correct sequence in the steps for removing
the FRU, as given in the drawings by the numbers in
square callouts.

When turning a screw to replace a FRU, turn it in the
direction as given by the arrow in the drawing.

When removing the FRU, move it in the direction as
given by the arrow in the drawing.

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 138.

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).
