Aptiva - 2161 Diagnostics - Index of symptoms, messages, error codes, or beeps

Applicable to: World-Wide

The tables below list 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" . 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 .

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" and "System Board Layout" )

In the tables below, an X in an error code can be any number. If you are unable to correct the problem using this index, go to Undetermined Problem .
