Repairing the BIOS IC

(Service Partners Only)

The notebook’s BIOS IC cannot be replaced separately. If it is defective, you must replace the
motherboard. In some cases, however, you might be able to reprogram a malfunctioning BIOS IC
using either e-DiagTools for Windows, a BIOS floppy disk, or a Crisis Recovery floppy disk.

If the notebook will boot sufficiently, use e-DiagTools for Windows or a BIOS floppy disk to reprogram
the BIOS IC. If you cannot boot the notebook adequately, use a Crisis Recovery floppy disk. See below
for instructions for all 3 methods.

Using e-DiagTools for Windows

CAUTION: The BIOS update completely replaces the previous BIOS, so follow these directions

exactly or you might damage the notebook. The BIOS update also resets the configurations in
the BIOS Setup utility—except for BIOS passwords—so record these before performing the
update.

Update the notebook’s BIOS as follows:

1. In Windows, exit any programs that are running.

2. Undock the notebook if it is docked, and remove any PCMCIA cards from it.

3. Connect the AC adapter to the notebook.

4. Connect any cables or equipment needed to connect to the Internet.

5. Select Start > Programs (or All Programs) > Hewlett-Packard > Notebook > HP e-DiagTools >

e-DiagTools for Windows.

6. Select Update, > Download New > OK. Follow the instructions that appear. Once the update process

begins, do not interrupt it.

The first time you make an Internet connection from this program on a particular unit, select
Change Settings in the Connect window to define your connection settings.

7. When the process completes, press the power button to reset the notebook.

BIOS updates are available from the HP Business Support Web site
Installation utilities and instructions for creating a BIOS floppy disk are provided with the updates.

Using a BIOS Floppy Disk

If you do not have a BIOS floppy disk, download the package from the Partnership Web site (see page vii)
under Product Support Information in the Service and Support Library. Follow the instructions for creating
the BIOS floppy disk.

CAUTION: Make sure to use the correct BIOS floppy disk for the notebook model you are
repairing.

The program does not verify the notebook model, so you could accidentally install the
wrong BIOS.

1. Insert the BIOS floppy disk in the floppy disk drive.

2. Turn on the notebook and allow it to boot from the BIOS floppy disk.

If the notebook does not turn on at all, do the following to boot from the BIOS floppy disk:
a. Unplug the AC adapter.
b. Press and hold Fn+B.
c. Plug in the AC adapter.
d. Release Fn+B.

NOTE: If the notebook will not boot from the BIOS floppy disk, try plugging the boot-block jumper
into the notebook’s parallel port. See the wiring diagram below.

3. The display goes blank for a minute or more while the BIOS is reprogrammed.

NOTE: If you plugged in a boot block jumper, unplug it before the notebook automatically reboots.

4. After the BIOS reprograms itself, check the BIOS version to make sure it is the latest version.

If necessary, download the latest BIOS version and reprogram the BIOS IC.

force has the option of creating models with ASP support using the specials process.

The serial number label on the bottom of the notebook indicates the ASP support status for that model. See
the following table.

Table 3-1. ASP Support Options

Serial Number Label ASP Support Status

“NoASP” No reimbursement to ASP for parts or labor. However the ASP is authorized to

repair the notebook, and reimbursement can be negotiated directly with the
customer.

“ASP” Parts and labor will be reimbursed to the ASP.

In other countries, ASP support is standard in most situations but you should check the marking on
the serial number label to verify the ASP support status for that model.

Troubleshooting

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

Check for customer abuse.

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.

Service Manual Troubleshooting and Diagnostics 3-3

Checking for Customer Abuse

Some notebooks might 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 notebook shows any of the following, customer abuse is declared:

 Missing parts
 Broken plastic parts
 Parts not original to the notebook
 Damaged or missing keys on the keyboard

Table 3-3 lists additional criteria for determining customer abuse to specific parts of the notebook.

NOTE: Parts damaged by customer abuse are not covered by the warranty.

3-4 Troubleshooting and Diagnostics Service Manual

Troubleshooting the Problem

Record pertinent information about the notebook:

• Model and serial number

• Operating system and version

• Software version (stored in hidden fileC:\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 are multiple symptoms, 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 possible causes.

 The e-Diagtools diagnostic program tests most of the notebook components using

automatic and interactive tests, and is your primary troubleshooting tool. Other tools include the
power-on self-test, WMI/Toptools (if installed), the BIOS Setup utility,
and the Sycard PCCtest. Table 3-2 on page 3-7 shows how you can use these tools
to isolate the cause of the notebook’s problem.

 The troubleshooting suggestions on page 3-8 include general suggestions for repairing notebooks

that show specific failure symptoms.

Swapping modules that might 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 reset button: this turns the notebook off, 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:

• e-Diagtools Basic Diagnostic Test. Run the basic test of the e-Diagtools diagnostic program (page

3-18).

–and–

• Function Tests. Run tests that check the repaired function, such as those in e-Diagtools

(page 3-18).

–and–

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