Additional Troubleshooting Procedures

Error Checking

If the problem recurs after you have checked and
corrected all of the above items, refer to Additional
Troubleshooting Procedures in this chapter.
This section provides a more detailed approach to
diagnostic testing and identification of a problem and
locating its source.
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 BIOS
User's Information section in this chapter for a list of
items to check for each error code and for an
explanation of the error beep codes.
