Preliminary Steps

Before running POST, complete the following steps:
1. If a Power-on password is established, type the password and press the Enter key. If
you do not know the password, clear the password (See
Password later in this chapter).
2. Run Compaq Diagnostics.
3. Turn off the Notebook and its external devices.
4. Disconnect any external devices you do not want to test.
Note: 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 both 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 that the hard drive is installed in the Notebook.
7. Ensure that the battery pack is installed and the Notebook is connected to an external
AC power source.
