Troubleshooting

This section provides troubleshooting information for Compaq Presario 1600XL Series
Portable Notebook. The basic steps in troubleshooting include:

1. Preliminary Steps

2. The Power-On Self Test (POST)

3. The recommended actions described in the diagnostic tables in case you are unable to
run POST, or if POST displays an error message.

When following the recommended actions in the Sections on Power-On Self Test (POST)
and Diagnostic Error Codes

, perform the steps in the order listed above. Rerun POST after
each recommended action until the problem is solved, and if no error message occurs.
Once the problem is solved, do not continue with any recommended actions remaining.

Note: If the problem is intermittent, check your computer several times to verify that
the problem is solved.

Preliminary Steps

Before running Power-On Self Test (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 Clearing the Power-On

Password).

2. Run Compaq Diagnostics

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 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.

Power-On Self Test (POST)

To run POST, complete these steps:

Turn off the Notebook, then turn it on again. As soon as the Compaq logo appears, press
the ESC key to clear the logo and display the POST messages as they occur.

If the Notebook does not beep, POST has successfully completed its test and detected no
errors. POST then reboot from the hard drive, or from a bootable diskette if one is installed
in the diskette drive.

However, if POST detects errors, these are indicated by messages displayed on the screen
and/or audible messages. A list of the POST error codes and what they mean is shown in
the table below.

Note: If the system is not functioning well enough to run POST, or if the display is not
functioning well enough to show POST error messages, refer to the Troubleshooting

Tables.
