Use the following strategy to prevent unnecessary expense for replacing and

servicing FRUs:

• If you are instructed to replace an FRU, but the replacement does not solve

the problem, reinstall the original FRU before you continue.

• Some computers have both a processor board and a system board. If you are

instructed to replace either of them, and replacing one of them does not solve

the problem, reinstall that board, and then replace the other one.

• If an adapter or a 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.

Important notice for replacing a system board

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

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

malfunction.

Attention: When handling a system board:

• Do not drop the system board or apply any excessive force to it.

• Avoid rough handling of any kind.

• Avoid bending the system board and hard pushing to prevent cracking at

each BGA (Ball Grid Array) chipset.
