Power-On Self Test (POST)

To run POST, complete these steps:

Turn off the Notebook, then turn it on again. As soon as the Compaq logo appears press the

ESC key to display the POST messages as they occur. Remember any POST error codes

that are displayed.

If the Notebook does not beep, POST has successfully completed its test and detected no

errors. The Notebook with automatically restart.

Note: If a bootable diskette is installed in the diskette drive the system will boot from

the diskette instead of the hard drive.

However, if POST detects errors, an error message will be displayed and/or an audible beep

will sound.

Note: If the Notebook is not functioning well enough to complete POST, or the display is

not functioning enough to show POST error messages, refer to the solution tables

later in

this chapter.
