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
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.
