TP 700,720 - Symptom to FRU index
Applicable to: World-Wide
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 ¿General Checkout—. This index also can be used to help you decide which FRUs to have available when servicing a computer.
If you cannot correct the problem using this index, go to ¿Undetermined Problem—.
IMPORTANT:
1. If you have both an error message and an incorrect audio response, diagnose the error message first.
2. If you cannot run the advanced diagnostic tests, but did receivea POST error message, diagnose the POST error message.
3. If you did not receive an error message, look fora description of your error symptoms in this index.
4. Check all power supply voltages before you replace the system board. See ¿Power Systems Checkout—.
5. If an error message is not listed, there isa device installed that requires an additional diskette or service manual. Refer to the diskette or service manual for that device.
How to Read POST Error Messages:
POST error messages are displayed on the screen as 3, 4, 5, or 8 digits. The error messages that can be displayed as shorter POST messages are highlighted in this Symptom-to-FRU Index.
Note:
Adjust the speaker volume before you power-on the computer.
