Introduction

Important service information

Important

BIOS and device driver fixes are

customer-installable. The BIOS and device drivers

are posted on the IBM support site

http://www.pc.ibm.com/support/

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.

Strategy for replacing FRUs

Before replacing parts

Make sure that all diskette fixes are installed before

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 but the

replacement 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 replacing one

of them does not correct the problem, reinstall that

board, and then replace the other one.

vIf an adapter or device consists of more than one FRU,

any of the FRUs may be the cause of the error. 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

The setup configuration on the computer you are

servicing may have been customized. Running

Automatic Configuration may alter the settings. Note

the current configuration settings (using the View

Configuration option); then, when service has been

completed, verify that those settings remain in

effect.

Strategy for replacing a hard-disk drive

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 may have been changed. Be extremely

careful during write operations such as copying,

saving, or formatting. If you select an incorrect drive,

data or programs can be overwritten.

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. Whatever causes the

first error code may also cause false error codes. 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.

Diskette compatibility matrix

The compatibility of each of the drives with the diskettes

for it is as follows:

Safety notices: multilingual translations

The safety notices are provided in English, French,

German, Italian, and Spanish, as follows:

Safety notice 1

Before the computer is powered-on after FRU

replacement, make sure all screws, springs, and

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 unitéen clientèle, vérifiez que

tous les ressorts, vis et autres pièces sont bien en

place et bien fixées. Pour ce faire, secouez l’unitéet

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, mußsichergestellt

werden, daßkeine Schrauben, Federn oder andere

Kleinteile fehlen oder im Gehäuse vergessen

wurden. Der Computer mußgeschüttelt und auf

Klappergeräusche geprüft werden. Metallteile

oder-splitter können Kurzschlüsse erzeugen.

Prima di accendere l’elaboratore dopo che éstata

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 ci

ÚÚ 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.
