    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 vi) 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.
     Open a new document based on the serial label template.
     Enter the information from the old serial label, and print the new label on plain white paper. The
    new label does not have barcodes.
     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.
     While holding the paper label in place, attach a serial label overlay into the outer recess. It covers
    and protects the serial label.

    The suggestions in this section can help isolate and repair the cause of a problem. To ensure quality
    repair, follow the basic troubleshooting steps shown below.
    Check the customers description
    of the problem and any supporting
    Try to duplicate the customers
    Troubleshoot the problem using:
      - Diagnostic tools.
      - Troubleshooting suggestions.
    Verify the repair by testing the

    Check for customer abuse.

    							HP Omnibook XE3 (Technology Codes GE and GD) Troubleshooting and Diagnostics 3-3
    Checking for Customer Abuse
    Some units may appear to have been damaged by customer abuse. Use these guidelines to help
    determine if this is the case:
    • If the shipping box is seriously damaged, customer abuse 
    cannot be declared.
    • If the damage 
    could have a cause other than customer abuse, customer abuse 
    cannot be declared.
    • If the unit shows any of the following, customer abuse is declared:
    … Missing parts.
    … Broken plastic parts.
    … Parts not original to the unit.
    … Damaged or missing keys on the keyboard.
    Table 3-2 on page 3-6 includes additional criteria for determining customer abuse to specific parts of
    the unit.
    Parts damaged by customer abuse are not covered by the warranty. 
    							3-4 Troubleshooting and Diagnostics HP Omnibook XE3 (Technology Codes GE and GD)
    Troubleshooting the Problem
    Record pertinent information about the notebook:
    • Model and serial number.
    • Operating system and version.
    • Software version (hidden file c:\version.inf).
    • 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, note 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 e-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. Table 3-1 on page 3-5 shows how you can use these tools to isolate the cause
    of the notebook’s problem.
    … The troubleshooting suggestions in Table 3-2 on page 3-6 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 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 all of the
    following tests:
    DiagTools Basic Diagnostic Test. Run the basic test of the e-DiagTools diagnostic program
    (page 3-22).
    Function Tests. Run tests that check the repaired function, such as in the e-DiagTools
    diagnostic program (page 3-22).
    Failed Tests. Run any other tests that failed during troubleshooting.
