fixes are located on the PC Company Bulletin Board
Service (BBS). The direct phone line for modem con-
nection 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.

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 ser-
vicing. Running Automatic Configuration may alter those
Introduction 1

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 high-
lighted 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 informa-
tion 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 Notices (Multi-lingual
Translations)
In this manual, safety notices appear in English with a
page number reference to the appropriate multi-lingual,
translated safety notice found in this section.
The following safety notices are provided in English,
French, German, Italian, and Spanish languages.
Safety Notice 1
Before the computer is powered-on after FRU replace-
ment, 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 lis-
tening 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 pi ces 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, muΒ sichergestellt
werden, daΒ keine Schrauben, Federn oder andere
Kleinteile fehlen oder im Gehäuse vergessen wurden.
Der Computer muΒ geschüttelt und auf
Klappergeräusche gepr¾ft 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 se encuentran sueltas dentro del sistema.
Compruébelo agitando el sistema y escuchando los
posibles ruidos que provocarõan. Las piezas metálicas
pueden causar cortocircuitos eléctricos.

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
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.

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. 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.
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.
Place removed covers and other parts in a safe
place, away from all personnel, while you are ser-
vicing 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.
Introduction 11

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 elec-
trical currents. Many customers have, near their equip-
ment, 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 elec-
trical 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
– 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 accesso-
ries for that tester.
