A 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 Power-On Self Test is a fast startup process that does not run all of the system level tests, such as the memory test. Disabling this feature causes all of the ROM-based system tests to run and booting takes longer to complete. ✎ For more information on Computer Setup, see the Computer Setup (F10) Utility Guide on the Documentation CD.

of the problem, and steps you can take to resolve the error condition.

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
