Aptiva - 2158/2163/2164 Diagnostics - Index of symptoms, error codes, messages, and beeps

Applicable to: World-Wide

How to Use Error Messages: Use the messages, error codes, and beeps combinations that occur to diagnose failures. If more than one failure occurs, begin the diagnosis from the first failure that appeared. The cause of the first failure can result in false messages, error codes, or beeps. If you did not receive any messages, error codes, or beeps, see if the symptom is listed in the third table below.

CAUTION: When you have deemed it necessary to replace a FRU, and have done so, you must run a total system check to ensure that no other activity has been affected by the change. This system check can be done through the diagnostics program (Select Diagnostics, then select and execute All Tests from PC-Doctor).

POST: Some diagnostic aids are resident in the machine, such as the Power-On Self Test (POST). The machine performs the POST each time it is powered on. Use this information throughout the diagnostic procedures. The POST is a series of system checks and initializations that verify the correct operation of the base system.

After a successful POST, the system attempts to load operating system. The system can be customized for different startup (boot) methods by the BIOS Setup Utility. See "Startup Options" on page 17 of the HMM.

The system's default startup sequence automatically looks for the operating system files in the hard disk if these files are not found in the diskette.

WARNING: Remember that POST does not test all areas, but only those that allow the system to operate well enough to run the diagnostics program.

The tables below list BIOS error codes, messages, beeps, and symptoms, along with their possible causes. The most likely cause is listed first. Make sure you complete all items in the cause or ôAction/FRUö column. When servicing a system, always begin with "Start" by clicking here - . If you are unable to correct the problem using these index tables, go to "Undetermined Problems" by clicking here - .

NOTE:
1. If an error message and incorrect audio response occur, diagnose the error message first.
2. If you cannot run the diagnostics program tests but did receive a POST error code and message, use the first table below to diagnose system problems.
3. If you cannot run the diagnostics program tests but did receive a POST error beeps, use the second table below to diagnose system problems.
4. If you did not receive any error message, look for a description of your error symptoms in the third table belowô

IMPORTANT: 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.

5. If you are unable to correct the problem by using the BIOS Error Codes, Messages, And Beeps List table and Error Symptoms List table, go to "Undetermined Problems" by clicking here - .

NOTE: To diagnose a problem, first find the BIOS error messages or codes in left column. If directed to a check procedure, replace the FRU indicated in the check procedure. If no check procedure is indicated, the first Action/FRU listed in right
column is the most likely cause.
