Repairing the BIOS IC

(HP Authorized Service Providers Only)

The BIOS IC of the Omnibook 500 is not replaceable:

If the BIOS IC is defective, you must replace the motherboard.

•

However, if the BIOS IC might only be corrupted, you can attempt to repair it using a Crisis

•

Recovery floppy disk—see below.

Note: Reprogramming the BIOS IC

A new BIOS IC contains only enough basic programming to boot the Omnibook. After installing a new motherboard, you must reprogram the BIOS IC, preferably with the latest BIOS. You can download the latest BIOS from the HP Notebook web site (see page vi)—follow the directions provided.

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

Caution

Make sure you are using the correct BIOS Crisis Recovery floppy for the Omnibook model you are repairing. The program does not verify the Omnibook model, so you could install the wrong BIOS image.

Dock the computer, and plug in an AC adapter.

Connect a floppy disk drive to the computer using a USB floppy cable, or dock the computer and

insert a floppy drive module into the expansion base. Insert the BIOS Crisis Recovery floppy in the floppy drive.

Turn on the computer. When the HP logo appears, press ESC to display the boot menu, then boot

from the floppy disk. If the computer does not turn on at all, boot from the floppy disk as follows:

Unplug the AC adapter.

•

Press and hold Fn+B.

•

Plug in the AC adapter.

•

Release Fn+B.

•

If the computer does not boot from the BIOS Crisis Recovery floppy, try plugging the boot-block

jumper into the expansion base parallel port, then go to the next step. See the wiring diagram below.

(In many situations you can skip this step—especially if the computer previously displayed a BIOS checksum error.)

2-32 Removal and Replacement HP Omnibook 500

Wait while the BIOS is reprogrammed—the display is blank for a minute or more while this

happens. If you plugged in a boot block jumper, unplug it before the computer automatically reboots. Make sure the BIOS is the latest version. (You can check this in the Main menu of BIOS Setup,

or in the BIOS menu of Windows e-DiagTools.) If necessary, reprogram the BIOS IC—see the note at the beginning of this topic.

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, take note of the functions that do work properly.

•

Separate Problems.

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

HP Omnibook 500 Troubleshooting and Diagnostics 3-3

•

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 computer’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 computer’s problem.



The troubleshooting suggestions on page 3-6 include general suggestions for repairing units with specific failure symptoms.

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

After you replace a component, the computer 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 computer and starts it in a known state.

Verifying the Repair

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

•

e-DiagTools Basic Diagnostic Test.

(page 3-19). – and –

•

Function Tests.

Run tests that check the repaired function, such as in the e-DiagTools

diagnostic program (page 3-19). – and –

•

Failed Tests.

Run any other tests that failed during troubleshooting.

Power-On Self-Test

Note

If Quiet Boot is enabled in BIOS Setup (the default setting), press ESC during boot to see POST messages.

The POST (Power-On Self-Test) is a series of initialization routines and diagnostic tests that the system BIOS runs when the computer boots. The system BIOS will not boot the operating system if the system memory, CPU, DMA, or interrupt controller fails the POST diagnostic tests. POST progress is indicated by a sequence of codes, and error messages are displayed if possible.

You should not necessarily interpret the failure of one or more POST tests as a hardware, software, or firmware failure. If an error message appears, all POST messages indicate a hardware, software, or firmware failure—some messages are for information only.

First, confirm the failure by performing a “clean” boot. If the computer fails to restart with a clean boot, it requires repair.

Remove all accessories, including expansion base, external floppy drive, PC Cards, printer,

external monitor, pointing device, and keyboard. Provide “clean” AC power—no auto adapter or unusual AC adapter configuration.

Press the system-off switch to start the computer from a known state.

Desktop and Windows M anagement Interfaces (DMI/WMI)

The Desktop Management Interface (Windows 98) and Windows Management Instrumentation (Windows 2000) are basically sets of rules for accessing information about a computer. DMI/WMI allows an application to determine, for example, the operating system being used, which hardware and software components are in the computer, and possibly whether any of the components need replacing. A local or remote application can use the DMI/WMI interface to check which hardware and software components are installed on your computer, and may be able to tell how well they are working or if they need replacement.

Installing the DMI Package

The DMI package is either preinstalled on the computer’s hard disk or can be downloaded from http://www.hp.com/toptools (the contents are the same in both cases). The package must be properly installed before it can be used.

To install the DMI/WMI preloaded on the hard disk:

Start Windows, if it is not already running.

Click Start, Programs, HP Toptools, Setup.

Using DMI/WMI

For a complete description of how to use DMI/WMI, see the following documentation provided with the computer:
