Important Service Information
Important
Diskette fixes are customer installable. The diskette
fixes are located on the PC Company Bulletin Board
Service (BBS). The direct phone line for modem
connection is 919-557-0001 or tieline 255-0001.
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 down-load information.
The Canadian BBS phone numbers are:
Montreal

FRU Replacement Strategy
Before Replacing Parts
Ensure that all diskette fixes are installed prior to
replacing any FRUs listed in this manual.
Use the following strategy to prevent unnecessary FRU
replacement and service expense:
Ÿ
If you are instructed to replace a FRU and that
does not correct the problem, reinstall the original
FRU before you continue.
Ÿ
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 the first
board that you replaced does not correct the problem,
reinstall the original board, then replace the other
(processor or system) board.
Ÿ
If an adapter or device consists of more than one
FRU, an error code may be caused by any of the
FRUs. 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.

Introduction
Attention
A customized setup configuration (other than default
settings) may exist on the computer you are servicing.
Running Automatic Configuration may alter those
settings. Note the current configuration settings (using
the View Configuration option) and verify that the
settings are in place when service is complete.
Hard Disk Drive Replacement Strategy:
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 might have been changed. Be extremely
careful during write operations such as copying,
saving, or formatting. Data or programs can be
overwritten if you select an incorrect drive.
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. The cause of the first error code can
result in false error codes being displayed. 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.
How to Read POST Error Messages: POST
error messages are displayed on the screen as three, four,
five, or eight digits. The error messages that can be
displayed as shorter POST messages are highlighted in
this index. Some digits will represent different information
for SCSI errors versus non-SCSI errors.
The following example shows which digits display the
shorter POST error messages and also defines the SCSI
information in an eight-digit error message.

All SCSI devices are set to a different SCSI ID. Duplicate
SCSI ID settings can generate a false error message. Use
the SCSI ID to determine whether the error message is
coming from an internal or an external device.

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.
Aunque las baterías principales tienen un voltaje bajo,
una batería cortocircuitada o con contacto a tierra
puede producir la corriente suficiente como para
quemar material combustible o provocar quemaduras
en el personal.

Introduction
Safety Inspection Guide: The intent of this
inspection guide is to assist you in identifying potentially
unsafe conditions on these products. Each machine, as it
was designed and built, had required safety items installed
to protect users and service personnel from injury. This
guide addresses only those items. However, good
judgment should be used 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:
Ÿ
Electrical hazards, especially primary power (primary
voltage on the frame can cause serious or fatal
electrical shock).
Ÿ
Ÿ
Explosive hazards, such as a damaged CRT face or
bulging capacitor
Mechanical hazards, such as loose or missing
hardware
The guide consists of a series of steps presented in a
checklist. 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 appropriate type
as specified in the parts listings.
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.
General Descriptions 13
Download from Www.Somanuals.com. All Manuals Search And Download.
Introduction
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:
Ÿ
Keep the parts in protective packages until they are
inserted into the product.
Ÿ
Ÿ
Avoid contact with other people.
Wear a grounded wrist strap against your skin to
eliminate static on your body.
Ÿ
Ÿ
Ÿ
Prevent the part from touching your clothing. Most
clothing is insulative and retains a charge even when
you are wearing a wrist strap.
Use the black side of a grounded work mat to provide
a static-free work surface. The mat is especially
useful when handling ESD-sensitive devices.
Select a grounding system, such as those listed
below, to provide protection that meets the specific
service requirement.
Note
The use of a grounding system 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.

11. If power problems appear only when the port
replicator is used, replace the port replicator.
Port Replicator Power Overload: If power
shutdown occurs intermittently when PC Card devices are
used through a port replicator with PC Card slots, suspect
an over-current problem. Some PC Card devices use
more power; if the maximum usage of each device occurs
simultaneously, the total current will exceed the limit,
thereby causing a power shutdown. Isolate this problem
by removing one of the devices, use the computer under
the same condition, and see whether a power shutdown
occurs. Do this procedure for all devices to determine the
cause.
Power Systems Checkout
To verify the symptom of the problem, power on the
computer using each of the following power sources:
1. Remove the battery pack.
2. Connect the AC Adapter and check that power is
supplied.

Checking the AC Adapter: You are here
because the computer fails only when the AC Adapter is
used:
Ÿ
If the power problem occurs only when the port
replicator is used, replace the port replicator.
If the power-on indicator does not turn on, check the
power cord of the AC Adapter for correct continuity
and installation.
Ÿ
Ÿ
If the operational charge does not work, go to
Checking Operational Charging.
1. Unplug the AC Adapter cable from the computer and
measure the output voltage at the plug of the AC
Adapter cable. See the following figure:

Replace the system board.
If the problem is not corrected, go to
“Undetermined Problems” section of each model.
Note: An audible 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 either
the system board or DC-DC card that the battery is
connected to. Then reinstall the battery pack. If the
reinstalled battery pack is not charged, go to the next
section.
Checking the Battery Pack: Battery charging will
not start until the Fuel-Gauge shows that less than 95% of
the total power remains; with this condition the battery
pack can charge to 100% of its capacity. This protects the
battery pack from being overcharged or having a
shortened life.
Do the following:
1. Power off the computer.
2. Remove the battery pack and measure the voltage
between battery terminals 1 (+) and 4 (−). See the
following figure:
Terminal
Voltage (V dc)
+ 0 to + 12.6
Ground (−)

4
3. If the voltage is less than +11.0 V dc, the battery pack
has been discharged. Recharge the battery pack.
Note: In this case, the battery pack is
over-discharged. It takes at least 3 hours to
recharge the battery pack 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 3 and 4. The
resistance must be 4 to 30 K ohm.
If the resistance is not correct, replace the battery
pack. If the resistance is correct, replace the system
board.

System Board and CPU Card Checkout
The processing functions are performed by both the
system board and the CPU card. Processor problems can
be caused by either FRU. However, the CPU card
generally has a lower probability of failure. If a numeric
code indicates the system board or the CPU card as a
failing FRU, or the CPU card is indicated by a diagnostic
test by showing FRU code 11, use the following procedure
to isolate the problem:
1. Run the system board test to verify the symptom.
This test verifies both the system board and the CPU
card. If no error is detected, return to “Checkout
Guide” on page 30.
Note: Don't touch the keyboard and pointing device
when the system board test is running. This
might cause an unexpected error.

2. If FRU code 10 appears, replace the system board
but do not replace the CPU card. Remove the CPU
card from the old system board and install it to the
new system board.
3. If FRU code 11 appears, reseat the CPU card.
4. Rerun the test to verify the fix.
5. If FRU code 11 remains, replace the CPU card.
If this procedure does not correct the problem, go to the
“Undetermined Problems” section for each model.
TrackPoint Checkout
If the TrackPoint does not work, check the configuration in
the ThinkPad Configuration program. If the configuration
of the TrackPoint is disabled, select Enable to enable it.
If this does not correct the TrackPoint problem, continue
with the following. After you use the TrackPoint, the
pointer drifts on the screen for a short time. This
self-acting pointer movement can occur when a slight,
steady pressure is applied to the TrackPoint pointer. This
symptom is not a hardware problem. No service actions
are necessary if the pointer movement stops in a short
period of time.
If a click button problem or the pointing stick problem
occurs, do the following:
1. Go to the Easy-Setup menu.
2. Select an item with the pointing stick.
3. Press any one of the click buttons.
4. Verify that the item is selected.
5. Move to another item with the pointing stick.

Running the Diagnostics
The device ID and error code indicate the detailed portion
of the FRU that caused the error. If replacing a FRU does
not correct the problem, see the device ID or error code
from the previous failure. If they have changed, the cause
might be that the new FRU is defective or that the FRU
was incorrectly installed.
Device ID: If an error is detected by the diagnostic
tests, a three-digit device ID is displayed, indicating the
suspected device.

tests, a four-digit FRU code is displayed. The FRU code
indicates two suspected FRUs. Replace the FRU that is
indicated by the two leftmost digits first; then replace the
FRU that indicated by the two rightmost digits. No FRU
is assigned to code 00. If only one FRU is suspected, the
other FRU code is 00. See the reference page before

Symptom-to-FRU Index
Symptom-to-FRU Index
The symptom-to-FRU index lists the symptoms and errors
and their possible causes. The most likely cause is listed
first.
Note: Perform the FRU replacement or actions in the
sequence shown in the “FRU/Action in Sequence”
column. If a FRU replacement did 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 the next possible
FRUs to be replaced when servicing a computer.
Numeric error codes show the errors detected in POST or
system operation. In the following error codes, X can be
any number.
If no codes are available, use narrative symptoms.
If the symptom is not listed, go to “Undetermined
Problems” on page 64.
Note: For IBM devices not supported by diagnostic
codes in the ThinkPad notebook computers,
see the manual for that device.

Note
If you cannot find a symptom or an error in this list
and the problem remains, see “Undetermined
Problems”
Intermittent Problems
Intermittent system hang problems can be caused by a
variety of reasons 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 recurring problem exists.
When analyzing an intermittent problem, do the following:
1. Run the advanced 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, installed devices are
incorrect, a short circuit is suspected, or the system is
inoperative. Follow these procedures to isolate the failing
FRU (do not isolate nondefective FRUs).

FRU Removals and Replacements
FRU Removals and Replacements
This section contains information about removals and
replacements:
Ÿ
Do not damage any part. Only certified and trained
personnel should service the computer.
The arrows in the “Removals and Replacements”
section show the direction of movement to remove a
FRU, or to turn a screw to release the FRU. The
arrows are marked in numeric order, in square
callouts, to show the correct sequence of removal.
If other FRUs must be removed before the failing
FRU is removed, they are listed at the top of the
page.
Ÿ
Ÿ
Ÿ
To replace a FRU, reverse the removal procedure
and follow any notes that pertain to replacement.
See “Locations” for internal cable connections and
arrangement information.
Ÿ
When replacing a FRU, use the correct screw as
shown in the procedures.
Reviews “FRU Replacement Notices” on page 19 before
replacing any FRU.
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
The battery pack contains small amounts of nickel.
Do not disassemble it, 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, or 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 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.
An electrostatic discharge (ESD) strap (P/N 6405959)
must be used to establish personal grounding.
