A.1 BIOS Error POST (Beep) Codes
During the POST (Power-On Self-Test) process, which is performed each time the system is
powered on, system errors may be detected.
Non-fatal errors
are those which, in most cases, allow the system to continue with the boot-
up process. The error messages normally appear on the screen.
Fatal errors
are those which will not allow the system to continue to boot up. If a fatal error
occurs, you should consult with your system manufacturer for possible repairs.
The fatal errors are usually communicated through repeated patterns of audible beeps. Each
pattern of audible beeps listed below corresponds to its respective error.
