Preliminary Steps

Before running the Power-On Self-Test (POST), complete the following steps:

1. If a Power-on password has been established, type the password and press the Enter key. If

the password is unknown, clear the password (See Clearing the Power-On Password

2. Run the Computer Checkup (TEST)

3. Turn off the Notebook and all external devices.

4. Disconnect any external device that does not need testing. Do not disconnect the printer if it

needs testing or if it is required to log error messages.

Important: If the problem only occurs when an external device is connected to the

Notebook, the problem may be related to the external device or its cable. Check this by

running POST both with and without the external device connected.

5. Install loopback plugs in the serial and parallel connectors if these ports need testing.

6. Ensure that the hard drive is installed in the Notebook.

7. Ensure that the battery pack is inserted into the Notebook, and that it is connected to an

external AC power source.

When these preliminary steps are completed, run the Power-on Self-Test (POST)
