Chapter 7. Symptom-to-FRU Index

The Symptom-to-FRU index lists error symptoms and possible causes. The most

likely cause is listed first. Always begin with Chapter 3, “General Checkout,” on

page 11. This index can also be used to help you decide which FRUs to have

available when servicing a computer. If you are unable to correct the problem

using this index, go to “Undetermined problems” on page 89.

Notes:

v If you have both an error message and an incorrect audio response, diagnose the error

message first.

v If you cannot run the diagnostic tests or you get a diagnostic error code when running a

test, but did receive a POST error message, diagnose the POST error message first.

v If you did not receive any error message, look for a description of your error symptoms

in the first part of this index.

v Check the hard disk drive jumper settings before you replace a hard disk drive.
