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 the Chapter 4 "General checkout" on page 35. 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 69.
Notes:
1. If you have both an error message and an incorrect audio response, diagnose the error message first.
2. If you cannot run the diagnostic tests or you get a diagnostic error message when running a test, but did receive a
POST error message, diagnose the POST error message first.
3. If you did not receive any error message, look for a description of your error symptoms in the first part of this index.
