8 POST error messages
This appendix 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
Computer Setup (F10) Utility on page 51.
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 may be encountered during POST.
NOTE: The computer will beep once after a POST text message is displayed on the screen.
