Power-On Self-Test (POST)

To run POST, complete the following action:
Turn off the Notebook, then turn it on again. As soon as the Compaq logo appears, press ESC to
clear the logo and display the POST messages as they occur.
If the Notebook does not beep, POST has successfully completed its test and detected no errors.
POST will automatically boot up the Notebook. If a bootable diskette is installed in the diskette drive,
the Notebook will boot from the diskette instead of the hard drive.
However, if POST detects errors, the Notebook will beep and may display a text message.
Note: If the system is not functioning well enough to complete POST, or the display is unable
to show POST error messages, refer to the section Solving Minor Problems.
