<strong>Chapter</strong> 7. Symptom-to-FRU Index<br />

Hard disk drive boot error<br />

Power Supply Problems<br />

The Symptom-to-FRU index lists error symptoms and possible causes. The most<br />

likely cause is listed first. Always begin with <strong>Chapter</strong> 4, “General Checkout,” on<br />

page 43. This index can also be used to help you decide which <strong>FRUs</strong> to have<br />

available when servicing a computer. If you are unable to correct the problem<br />

using this index, go to “Undetermined problems” on page 82.<br />

Notes:<br />

v If you have both an error message and an incorrect audio response, diagnose the error<br />

message first.<br />

v If you cannot run the diagnostic tests or you get a diagnostic error code when running a<br />

test, but did receive a POST error message, diagnose the POST error message first.<br />

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

in the first part of this index.<br />
