Aptiva - 2156 Diagnostics - Index of symptoms, messages, error codes, and beeps

Applicable to: Japan, United States

How to Use Error Messages: Use the messages, error codes, and beeps combinations that occur to diagnose failures. If more than one failure occurs, diagnose from the first failure that appears. 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 "Error Symptoms List" table below.

ATTENTION: When you have replaced a FRU, you must run the diagnostics 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 "BIOS Features Setup" on page 1-15.

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.

NOTE: 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, symptoms, messages, and beeps to their 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" .

If you are unable to correct the problem using these two index tables, go to "Undetermined Problems" .

OFFENDING SEGMENT:

This message is used in conjunction with the
I/O CHANNEL CHECK and RAM PARITY ERROR messages when the segment that has caused the problem has been isolated.

This will be displayed at the bottom of the screen when an error occurs that requires
you to reboot. Press any key and the system
will reboot.
