Troubleshooting

This chapter covers troubleshooting and resolving common problems associated with Compaq Presario 1800XL Series Notebooks. The basic steps in troubleshooting include:

1. Preparing the Notebook for troubleshooting as outlined in Preliminary Steps

on the

following page.

2. Performing the Power-On Self-Test (POST)

and observing any error messages

displayed.

Note: If the Notebook is unable to complete POST or an error message is displayed, skip to Step 3 below to try to resolve the problem.

3. Taking the recommended steps described later in this chapter to solve the problems.

When following the recommended actions provided in POST

and Diagnostic Error Codes, perform the steps in the order listed above. Rerun POST after each recommended action until the problem is solved, even if no error message occurs. Once the problem is solved, do not perform any remaining recommended solutions.

Note: If the problem is intermittent, check the Notebook several times to be sure that the problem is resolved.

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 Clearing the Power-On

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

Notebook, 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.

When these preliminary steps are completed, run POST

Clearing the Power-On Password

CAUTION: Clearing the Power-on password also removes all setup attributes that are programmed in the CMOS.

If you do not know the Power-on password, clear it by performing the following steps:

1. Turn off the Notebook.

2. Disconnect the power cord.

3. Remove the battery

4. Remove the Palmrest cover

5. Remove the keyboard

6. Remove the heat sink

7. Locate the CMOS switch to the right of the CD/DVD drive on the system board.

8. Slide the black switch to the right

holding it in this position for at least 15 seconds

to ensure that the password is cleared.

9. Reassemble the Notebook (refer to the Removal and Replacement

chapter later in

this MSG).

10. Turn on the Notebook to verify that the Power-on password has been cleared. If it has not been cleared, repeat this procedure.

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 display the POST messages as they occur. Remember any POST error codes that are displayed.

If the Notebook does not beep, POST has successfully completed its test and detected no errors. The Notebook will automatically restart.

Note: If a bootable diskette is installed in the diskette drive, the system will boot from the diskette instead of the hard drive.

However, if POST detects errors, the Notebook will beep and/or display a text message.

Note: If the Notebook is not functioning well enough to complete POST, or the display is unable to show POST error messages, refer to the section Solving Minor Problems in this chapter.

Compaq Diagnostics

Compaq Diagnostics utilities come pre-installed on 1800XL Series Notebooks. Run the diagnostic utilities to view or test system information and external devices. If you run Compaq Diagnostics from a diskette, be sure that the diagnostic program is version 10.11 or later.

The Diagnostics menu includes the following utilities:

• Checkup (TEST)

• View System Information (INSPECT)

• Prepare Notebook for a Compaq Service Call (RemotePaq)

Customers are encouraged to run the Diagnostics utilities to try to solve a problem before calling for support. Checkup (TEST) to a file and printing or saving the error log. The View System Information (INSPECT)

should be run with the options for saving the device list

utility should also be run with the option for printing or saving the information. Customers should have these files or the printed information available when calling for support.

Checkup (TEST)

TEST is included on the Compaq Diagnostics Diskette. TEST determines if the various Notebook components and devices are recognized by the system and are functioning properly. You can display, print, or save the information generated by TEST.

Follow these steps to run TEST:

1. Plug the Notebook into an external power source. (A low-battery condition could interrupt the program.)

2. Turn on the external devices you want to test. Connect the printer if you want to print a log of error messages.

3. Insert the Compaq Diagnostics Diskette in the diskette drive.

4. Turn on or restart the Notebook. The Notebook boots from the diskette, and after a few seconds, the diagnostics Welcome screen is displayed.

5. Press Enter to continue. The Diagnostics menu is displayed.

6. Select Computer Checkup from the Diagnostics menu. The Test Option menu is displayed.

7. Select View the Device List from the Test Option menu. A list of installed Compaq devices is displayed.

8. If the list of installed devices is correct, select OK. The Test Option menu is displayed.

Note: If the list is incorrect, ensure that any new devices are installed properly and run Checkup again.

9. Select one of the following from the Test Option menu:

• Quick Check Diagnostics. Runs a quick, general test on each device with

minimal prompts. If errors occur, they are displayed when the testing is complete. You cannot print or save the error messages.

• Automatic Diagnostics. Runs unattended, maximum testing of each device with

minimal prompts. You can choose how many times to run the tests, stop on errors, or print or save a log of errors.

• Prompted Diagnostics. You can choose attended or unattended testing. Allows

the most control over testing options. You can choose to stop on errors, or choose to print or save a log of errors.
