Index of Symptoms, Messages, Error Codes, or Beeps

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 Table 2-3, 'Error Symptoms List'.
-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 'Advanced Setup'. 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.

Table 2-1 lists BIOS Error Codes, Messages, to their possible causes,
Table 2-2 lists BIOS Error Codes - Beep Symptoms
Table 2-3 lists Processor, System Board - Ports & Devices error symptoms and 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'.

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

If you cannot run the diagnostics program tests but did receive a POST error code, diagnose the POST error message.

If you did not receive any error message, look for a description of the error symptoms in 'Error Symptoms List'.

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 Cable Connector Specifications' and 'Machine Type 2165 System Board Layout'.)

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'.
