Power-On Self Test (POST)
To run POST, complete these steps:
Turn off the computer, then turn on the
computer. As soon as the Compaq logo
appears press the ESC key to clear the
logo and display the POST messages as
they occur.
If POST does not detect any errors, the
computer will not beep. This indicates
successful completion of the POST test.
POST has run successfully and boots
from the hard drive (or from a bootable
diskette if one is installed in the diskette
drive).
If POST detects errors, the errors are
indicated by screen and/or audible
messages. A list of the POST error codes
and their descriptions are 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.
