7 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 nonerror 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 Computer Setup (F10) Utility on page 60. POST numeric codes and text messages This section identifies those POST errors that have numeric codes associated with them. The section also includes some text messages that you might encounter during POST. NOTE: The computer beeps once after a POST text message is displayed on the screen.
