General Descriptions
This chapter includes the descriptions for all ThinkPad
models. Some descriptions might not apply to the
particular computer.
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 down-load information.
The Canadian BBS phone numbers are:
Montreal 514-938-3022
Toronto 905-316-4255
Vancouver 604-664-6464
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

All manuals and user guides at all-guides.com

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 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.
Shorter POST Messages
"""""""""""""""""""""
" " " " "
"""""""""""""""""""""""""""""""""""""""""
" ð" ð" ð" ð" ð" ð" ð" ð"
"""""""""""""""""""""""""""""""""""""""""
" " " " " " " "
Reserved """"""Size (SCSI)
""""""""""" " " Slot Number (SCSI)
Device Code " Logical Unit Number (SCSI)
ID (SCSI)
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.

General Descriptions 3
All manuals and user guides at all-guides.com

Safety Notice 1
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 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 ciÞ
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 provocarían. Las piezas metálicas
pueden causar cortocircuitos eléctricos.
