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 reboot 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 displayed on the screen 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 Troubleshooting Tables.
