POST error messages

This section 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 POST mode selection determines the speed at which the computer loads the operating system and
the extent to which it is tested.
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.
You can enable Full Boot 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 about Computer Setup, see

POST numeric codes and text messages
