BIOS Error Codes
A.1 BIOS Error Beep (POST) Codes
During the POST (Power-On Self-Test) routines, which are performed each time the system
is powered on, errors may occur.
Non-fatal errors are those which, in most cases, allow the system to continue the boot-up
process. The error messages normally appear on the screen.
Fatal errors are those which will not allow the system to continue the boot-up procedure. If
a fatal error occurs, you should consult with your system manufacturer for possible repairs.
These fatal errors are usually communicated through a series of audible beeps. The table
below lists some common errors and their corresponding beep codes encountered by users.
