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 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 then re-boots from the hard drive, or from a bootable diskette if one is
installed in the diskette drive.
However, if POST detects errors, these are indicated by messages on the display screen
and/or audible messages. A list of the POST error codes and what they mean is shown in
the table below.
