Hardware Maintenance Manual Symptom-to-FRU Index 8 The Symptom-to-FRU index lists error symptoms and possible causes. The most likely cause is listed first. Always begin with Chapter 4, "General Checkout," on page 13. 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 27. Notes • If you have both an error message and an incorrect audio response diagnose the error message first. • 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. • If you did not receive any error message look for a description of your error symptoms in the first part of this index.
