							Introduction
Important service information
ImportantBIOS 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 partsMake 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 driveAlways 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 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 cheéstata
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 provocarían. Las piezas metálicas
pueden causar cortocircuitos eléctricos.
