If POST finishes without detecting any problems, the first screen of your operating system or application program appears (if you have not set a power-on password). If you have set a power-on password, a password prompt appears. You must enter your password before the first screen of your operating system or application program will appear. (For further information on using passwords, refer to "System Security" on page 45.) If Power On Status is Enabled and POST detects a problem, you will hear multiple beeps or no beep. In most cases, an error code appears in the top left corner of the screen, and in some cases a description of the error is displayed beside the code. (Note that the screen will sometimes display multiple error codes and descriptions.) For more information about what caused an error message to appear and what action to take, refer to "Solving POST Error Message Problems" on page 66 and "POST Message Charts" on page 69. If you hear no beep at all during POST, refer to "Troubleshooting Charts" on page 87. You might need to have your computer serviced. Error Messages Error messages that appear on the screen might be text, numeric, or both.

For more information about what caused an error message to appear and what action to take, refer to "Solving POST Error Message Problems" on page 66 and "POST Message Charts" on page 69. Software-generated error messages Messages that appear if a problem or conflict is detected by the application program, the operating system, or both.
