Important notice for replacing a system board

Some components mounted on a system board are very sensitive. Improper

handling of a system board can cause damage to those components, and may

cause a system malfunction.

Attention: When handling a system board:

v Do not drop a system board or apply any excessive force to it.

v Avoid rough handling of any kind.

v Avoid bending a system board and hard pushing to prevent cracking at each

BGA (Ball Grid Array) chipset.

How to use error message

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.
