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 Chapter4, “General Checkout,” on

page 43. This index can also be used to help you decide which FRUs to have

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

using this index, go to “Undetermined problems” on page 82.

Notes:
vIf you have both an error message and an incorrect audio response, diagnose the error
message first.
vIf 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.
vIf you did not receive any error message, look for a description of your error symptoms
in the first part of this index.
