Preliminary Steps
Before running POST, complete the
following preliminary steps:
1. 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.
2. Run
Computer Checkup.
3. Turn off the computer and its
external devices.
4. 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.
5. Install loopback plugs in the serial
and parallel connectors if you would
like to test these ports.
6. Ensure the hard drive is installed in
the computer.
7. 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.
