Introduction
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 download information.

Winnipeg 204-934-2735
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:
If you are instructed to replace a FRU and that
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 the first
board that you replaced does not correct the problem,
reinstall the original board, then replace the other
(processor or system) board.
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.
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
2 ThinkPad i Series 1400/1500 HMM
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. The following
example shows which digits display the shorter POST error
messages and also defines the SCSI information in an
eight-digit error message.
POST
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 Notice 7
Though main batteries have low voltage, a shorted or
grounded battery can produce enough current to burn
combustible materials or personnel.
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 Kurzschluβ 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

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:
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.
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.
objects that weigh more than 16 kg (35 lb) or
objects that you think are too heavy for you.
Do not perform any action that causes hazards to the
customer, or that makes the equipment unsafe.
ThinkPad i Series 1400/1500
Do not attempt to lift any
11
Before you start the machine, ensure 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 tool case 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. Ensure that your sleeves
are fastened or rolled up above your elbows. If your
hair is long, fasten it.
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.
Do not wear jewelry, chains, metal-frame eyeglasses,
or metal fasteners for your clothing.
Attention: Metal objects are good electrical conduc-
tors.
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.
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.
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.
Do not work alone under hazardous conditions or
near equipment that has hazardous voltages.
Disconnect all power before:
– Performing a mechanical inspection
12 ThinkPad i Series 1400/1500 HMM
– Working near power supplies
– Removing or installing main units
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: 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.
– 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. Regularly inspect and maintain your electrical hand tools
for safe operational condition.
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.
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
ThinkPad i Series 1400/1500 13
– Motor generators
and similar units. (This practice ensures correct
grounding of the units.)
If an electrical accident occurs:
– Use caution; do not become a victim your-
self.
– 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
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
bulging capacitor.
Mechanical hazards, such as loose or missing hard-
ware.
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.
14 ThinkPad i Series 1400/1500 HMM
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:
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, 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 batteryoperated 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.

Read this first
Before you go to the check procedures, be sure to read
this section.
Important Notes
Only certified trained personnel should service
the computer.
Read the entire FRU service procedures before
replacing any FRUs.
Use new nylon-coated screws when you replace
FRUs.
Be extremely careful during write operations such
as copying, saving, or formatting. Drives in the
computer that you are servicing might have been
rearranged or the drive startup sequence might have
been altered. If you select an incorrect drive, data or
programs could be overwritten.
Replace FRUs only for the correct model. When
you replace a FRU, make sure that the model of the
machine and 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 failure can
occur for a variety of reasons that have nothing to do
with a hardware defect, such as: cosmic radiation,
electrostatic discharge, or software error. FRU
replacement should be considered only when a recurring problem exists. In this case, clear the error log
and run the test again. Do not replace FRUs if log
errors do not reappear.
Be careful not to replace a non-defective FRU.
