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.ibm.com/pc/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 expense

for replacing and servicing FRUs:

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.

Safety notices: multilingual translations

In this manual, safety notices appear in English with a

page number reference to the appropriate multilingual,

translated safety notice found in this section.

The following safety notices are provided in English,

French, German, Hebrew, Italian, and Spanish.

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 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

ciò scuotendo l’elaboratore e prestando attenzione ad eventuali

rumori; eventuali parti o pezzetti metallici possono provocare

cortocircuiti pericolosi.

(continued)

Safety notices

Introduction 5

(continuation of safety notice 1)

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.
