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, they are indicated by displayed messages and/or audible
messages. A list of the POST error codes and what they mean is shown in the table below.
Note: If the system is not functioning well enough to run POST, or if the display is not
functioning well enough to show POST error messages, refer to the
tables.
