Figure 2-26. Installing the PCMCIA Doors

Installing a New Serial Number Label

Download the latest version of the serial number label template (Microsoft Word format) from the
Partnership Web site (see page vii) under Support/Service in Technical Support Information, or from
http://www.mcd.hp.com. Store it with other Word templates on a PC connected to a laser printer. The
latest version includes fields for warranty period and manufacturing location.

1. Open a new document based on the serial label template.

2. Enter the information from the old serial label, and print the new label on plain white paper. The

new label does not have barcodes.

3. Carefully cut out the new serial label just inside the border and place it into the inner recess in the

bottom case. The bottom of the label goes toward the front of the case.

4. While holding the paper label in place, attach a serial label overlay into the outer recess. It covers

and protects the serial label.

Troubleshooting

The suggestions in this section can help isolate and repair the cause of a problem. To ensure quality
repair, HP recommends that you follow the basic troubleshooting steps shown in the illustration
below.

Check the customer’s description
of the problem and any supporting
information.

Try to duplicate the customer’s
problem.

Troubleshoot the problem using

- Diagnostic tools.

- Troubleshooting suggestions.

Verify the repair by testing the
functionality of the complete unit.

Figure 3-1. Basic Troubleshooting Steps

3-2 Troubleshooting and Diagnostics HP OmniBook XE3

Troubleshooting the Problem

Record pertinent information about the notebook:

• Model and serial number.

• Operating system and version.

• BIOS version.

• Accessories and peripherals used.

Analyze the problem:

Observe Symptoms. Using the customer’s information, try to duplicate the problem. Determine

•

how the problem differs from proper behavior. Also, take note of the functions that do work
properly.

Separate Problems. If there is more than one symptom, separate them into distinct problems.

•

•

Consider Causes. Keep in mind possible causes for each problem. Use the diagnostic tools and

troubleshooting suggestions to help find the possible causes.

 The DiagTools diagnostic program tests most of the notebook’s components using automatic

and interactive tests, and will be your primary troubleshooting tool. Other tools include the
power-on self-test, DMI/TopTools (if installed), the BIOS Setup utility, and the Sycard
PCCtest. The table on page 3-4 shows how you can use these tools to isolate the cause of the
notebook’s problem.

 The troubleshooting suggestions on page 3-5 include general suggestions for repairing units

that show specific failure symptoms.

Swapping modules that may be defective with others known to be good is generally an ideal way to
find the module responsible for the problem. A failure symptom is rarely caused by more than one
module, so you will not usually need to replace more than one module to correct a particular failure.

After you replace a module, the notebook will normally be in a confused state and lock up when you
apply power. If this happens, press the system-off switch: this resets the notebook, so that you can
restart it in a known state.

Verifying the Repair

Before returning the repaired notebook to the customer, verify the repair by running the following
tests:

DiagTools Basic Diagnostic Test. Run the basic test of the DiagTools diagnostic program

•

(page 3-17).

–and–

Function Tests. Run tests that check the repaired function, such as in the DiagTools diagnostic

•

program (page 3-17).

–and–

Failed Tests. Run any other tests that failed during troubleshooting.
