Additional Troubleshooting Procedures
This section provides a more detailed approach to identifying a
problem and locating its source.
Error Checking
Each time you turn on the system, the POST runs automatically
and checks the system board, CPU module, memory, keyboard,
and most installed peripheral devices.
If POST finds an error, it displays an error message and, in case
there is a problem with the display, puts out a series of long and
short beeps. One short beep means the system passed POST.
Refer to the “Error Messages” section in this chapter for a list of
items to check for each error code and for an explanation of the
error beep codes.
