Preliminary Steps

 

IMPORTANT:

Use AC power when running POST, Computer Setup, or Computer Checkup. A low battery condition could initiate Hibernation and interrupt the test.

Before running POST, complete the following steps:

1. If a power-on password has been established, type the password and press Enter.  If the password is not known, clear the password.

2. Ensure the hard drive is installed in the computer.

3. Ensure that the battery pack is installed in the computer and the power cord is connected to the computer and plugged into an external AC power source.

4. Turn on the computer.

5. Run
Computer Setup.

6. Turn off the computer and its external devices.

7. Disconnect any external devices that you do not want to test. If you want to use the printer to log error messages, leave it connected to the computer.

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.

8. Use Compaq Utilities and loopback plugs in the serial and parallel connectors if you plan to test these ports.

When the preliminary steps are completed, you are ready to run POST.
