Symptom-to-FRU index (6565/6868/6878)

Symptom-to-FRU index (6565/6868/6878)

The Symptom-to-FRU index lists error symptoms and possible causes. The most likely cause is listed first. Always begin with General Checkout.

See IBM PC Enhanced Diagnostics Error Codes when running diagnostics. This index can also be used to help you decide which FRUs to have available when servicing a computer. If you are unable to correct the problem using this index, go to Undetermined Problems.

Notes:

•  If you have both an error message and an  incorrect audio response, diagnose the error message first.
•  If you cannot run the diagnostic tests or you get  a diagnostic error code when running a test, but  did receive a POST error message, diagnose the POST error message first.
•  If you did not receive any error message, look for  a description of your error symptoms in the first part of this index.
•  Check all Power Supply  voltages before you replace the system board.
•  Check the Hard Disk Drive Jumper Settings  before you replace a hard disk drive.

  -IMPORTANT-

1.  Some errors are indicated with a series of beep codes.  See Beep Symptoms.
    Type 6565/6868/6878 computers default to come up quiet  (No beep and no memory count and checkpoint  code display) when no errors are detected by POST.  To enable Beep and memory count and  checkpoint code display when a successful POST occurs:
   •   Enable Power on Status in setup.  See Setup Utility program.
2.  The processor is a separate FRU from the  system board; the processor is not included with  the system board FRU.
