POST Beep Codes

POST Beep Codes

The Power On Self-Test generates a beeping sound to indicate successful completion of POST or to indicate that the tests detect an error.
One beep and the appearance of text on the display indicates successful completion of the POST.
More than one beep indicates that the POST detects an error.

Note: Type 6563/6564/6565/6574/6868/6878 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:

  1.  Enable Power on Status in setup. See 'Setup Utility program'.
