POST error messages
This chapter lists the error codes, error messages, and the various indicator light and audible sequences that you
may encounter during Power-On Self-Test (POST) or computer restart, the probable source of the problem, and
steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count and non-error
text messages. If a POST error occurs, the screen will display the error message. To manually switch to the POST
Messages Enabled mode during POST, press any key (except F10, F11, or F12). The default mode is POST
Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are determined
by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory test. Full
Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish the
schedule, reconfigure the computer to the Full Boot Every x Days mode, using Computer Setup.
NOTE:
For more information on Computer Setup, see
POST numeric codes and text messages
This section covers those POST errors that have numeric codes associated with them. The section also includes
some text messages that might be encountered during POST.
NOTE:
The computer will beep once after a POST text message is displayed on the screen.
