Preliminary Steps
Before running POST,
complete the following preliminary steps:
If a power-on password has been
established, type the password and press the Enter key. If the password is
not known, clear the password.
Run Compaq
diagnostics.
Turn off the computer and its
external devices.
Disconnect any external devices
that you do not want to test. Do not disconnect the printer if you want to test it or use
it to log error messages.
IMPORTANT: |
If the problem only occurs when an
external device is connected to the computer, the problem may be related to the external
device or its cable. Verify this by running POST with and without the external device
connected. |
Install loopback plugs in the
serial and parallel connectors if you would like to test these ports.
Ensure the hard drive is installed
in the computer.
Ensure that the battery pack is
inserted in the computer and the computer is connected to an external AC power source.
When the preliminary steps are completed, you are
ready to run POST .
