Chapter 7. Symptom-to-FRU index
The Symptom-to-FRU index lists error symptoms and possible causes. The most likely cause is listed rst.
Always begin with the Chapter 4 “General checkout” on page 33
. You can use this index to help you decide
which FRUs are needed when servicing a computer. If you are unable to correct the problem using this
index, go to “Undetermined problems” on page 64.
Notes:
1. If you have both an error message and an incorrect audio response, diagnose the error message rst.
2. 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 rst.
3. If you did not receive any error message, look for a description of your error symptoms in the rst part of this index.
