Introduction

Important service information

Important

BIOS and device driver fixes are

customer-installable. The BIOS and device drivers

are posted on the customer support site

http://www.lenovo.com/think/ support

Advise customers to contact the Customer Support

Center at 800-426-7378 if they need assistance in

obtaining or installing any diskette fixes.

Customers in Canada should call the Customer

Support Center 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 aFRU but the

replacement does not correct the problem, reinstall

the original FRU before you continue.

vSome computers have both aprocessor 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 adevice 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 ahard disk drive

Always try to run alow-level format before replacing ahard

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 whether the error symptom is

listed in the Symptom-to-FRU Index for the computer you

are servicing.

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.

effettuata la sostituzione di una FRU, accertarsi che

tutte le viti, le molle etutte le altri parti di piccole

dimensioni siano nella corretta posizione enon siano

sparse all’interno dell’elaboratore. Verificare ciò

scuotendo l’elaboratore eprestando attenzione ad

eventuali rumori; eventuali parti opezzetti 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 yno
