Introduction
Important Service Information
Important
Diskette fixes are customer-installable. The diskette
fixes are posted on the IBM support site
http://www.pc.ibm.com/support/ .
Advise customers to contact the IBM
®
HelpCenter
®
at 800-772-2227 if they need assistance in obtaining
or installing any diskette fixes.
Customers in Canada should call IBM
®
HelpCenter
®
at 800-565-3344 for assistance or download
information.
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:
vIf you are instructed to replace a FRU and that does
not correct the problem, reinstall the original FRU
before you continue.
vSome 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.
vIf 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.
vR31 : When CPU is replaced, the heat sink should be
replaced with new one also.
1
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 over-written 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.
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.

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:
vObserve good housekeeping in the area of the
machines during and after maintenance.
vWhen lifting any heavy object:
1. Ensure you can stand safety 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.
vDo not perform any action that causes hazards to the
customer, or that makes the equipment unsafe.
vBefore you start the machine, ensure that other service
representatives and the customer’s personnel are not in
a hazardous position.
vPlace removed covers and other parts in a safe place,
away from all personnel, while you are servicing the
machine.
vKeep your tool case away from walk areas so that other
people will not trip over it.
vDo not wear loose clothing that can be trapped in the
moving parts of a machine. Ensure that your sleeves
are fastened or rolled up above your elbows. If your hair
is long, fasten it.
vInsert the ends of your necktie or scarf inside clothing or
fasten it with a nonconductive clip, approximately 8
centimeters (3 inches) from the end.
vDo not wear jewelry, chains, metal-frame eyeglasses, or
metal fasteners for your clothing.
Attention: Metal objects are good electrical
conductors.
vWear 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.
vAfter service, reinstall all safety shields, guards, labels,
and ground wires. Replace any safety device that is
worn or defective.
MT 2656, 2657, 2676 13
vReinstall all covers correctly before returning the
machine to the customer.
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.
vFind 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.
vDo not work alone under hazardous conditions or near
equipment that has hazardous voltages.
vDisconnect all power before:
–Performing a mechanical inspection
–Working near power supplies
–Removing or installing main units
vBefore 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.
vIf 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: There must be a complete circuit to
cause electrical shock. 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.
14 ThinkPad R30/R31 HMM
–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
safety sections of maintenance information. Use
extreme care when measuring high voltages.
vRegularly inspect and maintain your electrical hand tools
for safe operational condition.
vDo not use worn or broken tools and testers.
vNever assume that power has been disconnected from
a circuit. First, check that it has been powered-off.
vAlways 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.
vDo 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.
vDo 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.)
vIf 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 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
MT 2656, 2657, 2676 15
you can continue without first correcting the problem.
Consider these conditions and the safety hazards they
present:
vElectrical hazards, especially primary power (primary
voltage on the frame can cause serious or fatal
electrical shock).
vExplosive hazards, such as a damaged CRT face or
bulging capacitor.
vMechanical 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.
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.
16 ThinkPad R30/R31 HMM
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:
vKeep the parts in protective packages until they are
inserted into the product.
vAvoid contact with other people.
vWear a grounded wrist strap against your skin to
eliminate static on your body.
vPrevent the part from touching your clothing. Most
clothing is insulative and retains a charge even when
you are wearing a wrist strap.
vUse 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.
vSelect 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

Symptom-to-FRU Index
The Symptom-to-FRU Index lists the symptoms and errors
and the possible causes. The most likely cause is listed
first.
Note: Perform the FRU replacement or actions in the
sequence shown in the FRU/Action columns. If a
FRU does not solve the problem, put the original
part back in the computer. Do not replace a
non-defective FRU.
This index can also be used to help you decide which
FRUs should be available when servicing a computer.
Numeric error codes show the errors detected in POST or
system operation (runtime). 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 49.

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, electronic discharge, or
software errors. FRU replacement should only be
considered when a recurring problem exists.
When analyzing on intermittent problem, do the following:
48 ThinkPad R30/R31 HMM
1. Run the diagnostic test for the system board at least
10 times.
2. If no error is detected, do not replace any FRUs.
3. If any error is detected, replace the FRU. Rerun the
test to verify that there are no more errors.
Undetermined Problems
The diagnostic tests did not identify which adapter or
device failed, which installed devices are incorrect, whether
a short circuit is suspected, or whether the system is
inoperative. Follow the procedures below to isolate the
failing FRU.
Verify that the power supply being used at the time of the
failure is operating correctly.
1. Power off the computer.
2. Check the cables, wires, and connectors for short
circuits and open circuits. Visually check them for
damage. If any problems are found, replace the FRU.
3. Remove or disconnect all of the following devices:
vNon-IBM devices
vPrinter, external mouse & keyboard, and other
external devices
vBattery pack
vHard disk drive
vCD-ROM drive/Diskette drive (optional)
vPC Card (PCMCIA)
4. Power on the computer.
5. Determine if the problem has changed.
6. If the problem does not occur again, 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 non-defective FRU.

FRU Applicable test
TrackPont or Pointing
device
If the TrackPoint does not work, see if an
external PS/2 mouse is connected to the
mouse/keyboard connector and remove
it. The TrackPoint is automatically
disabled if an external PS/2 mouse is
attached. Check also if the TrackPoint
driver is correctly installed by accessing
Windows Device Manager via the System
icon in the Control Panel.
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 this does not correct the TrackPoint
problem, continue with the following:
Mouse (Interactive Tests).
Hard disk drive Fixed Disks (Diagnostics)

FRU Applicable test
TrackPont or Pointing
device
If the TrackPoint does not work, see if an
external PS/2 mouse is connected to the
mouse/keyboard connector and remove
it. The TrackPoint is automatically
disabled if an external PS/2 mouse is
attached. Check also if the TrackPoint
driver is correctly installed by accessing
Windows Device Manager via the System
icon in the Control Panel.
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 this does not correct the TrackPoint
problem, continue with the following:
Mouse (Interactive Tests).
Hard disk drive Fixed Disks (Diagnostics)
CD-ROM drive CD-ROM, DVD, CD-RW, DVD/CD-RW
(Interactive Tests)
Memory 1. If a DIMM is installed, remove it and
run Memory Test-Quick (Diagnostics)
2. If the problem does not recur, replace
the DIMM and run the test again.
3. If the test does not detect the error,
run Memory Test-Full (Diagnostics)
Fan 1. Power on system and check the air
turbulence at the louver at the rear of
the computer.
2. Run the fan test in Other Devices
(Diagnostics).

FRU Applicable test
TrackPont or Pointing
device
If the TrackPoint does not work, see if an
external PS/2 mouse is connected to the
mouse/keyboard connector and remove
it. The TrackPoint is automatically
disabled if an external PS/2 mouse is
attached. Check also if the TrackPoint
driver is correctly installed by accessing
Windows Device Manager via the System
icon in the Control Panel.
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 this does not correct the TrackPoint
problem, continue with the following:
Mouse (Interactive Tests).
Hard disk drive Fixed Disks (Diagnostics)
CD-ROM drive CD-ROM, DVD, CD-RW, DVD/CD-RW
(Interactive Tests)
Memory 1. If a DIMM is installed, remove it and
run Memory Test-Quick (Diagnostics)
2. If the problem does not recur, replace
the DIMM and run the test again.
3. If the test does not detect the error,
run Memory Test-Full (Diagnostics)
Fan 1. Power on system and check the air
turbulence at the louver at the rear of
the computer.
2. Run the fan test in Other Devices
(Diagnostics).
