Index	of	Symptoms, Messages,		Error Codes,		or
Beeps
Table 2-1		on page 2-11	lists	failure	symptoms		and possible causes. The
most likely cause is listed first. Make sure							you complete all items in the
cause	or	“Action/FRU” column. When servicing a					system, always begin with
“Start” on		page 2-2. This index can			also	be	used to help you decide which
FRUs	to	have available	when	servicing a		system.

If you are unable to correct the problem using this index, go to “Undetermined Problem” on page 2-56.

Notes:

1.If an error message and incorrect audio response occur, diagnose the error message first.

2.	If	you	cannot run the Diagnostics and Utilities					tests	but did receive	a
	POST	error	code,		diagnose the POST error message.
3.	If	you	did	not	receive	any error	message, look	for	a description of	your
	error symptoms			in	the first	part of	this index.

4. Check all power supply voltages, switch, and jumper settings before you replace the system board. Also check the power supply voltages if you have a system no-power condition. (See “Power Supply” on page 2-34, “System Board Layout—Type A-1” on page 5-2, and “System Board Layout—Type A-2” on page 5-5)
