Repairing the BIOS IC

(HP Authorized Service Providers 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 three 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. Click Start, Programs (or All Programs), Hewlett-Packard, Notebook, HP e-DiagTools,

e-DiagTools for Windows.

6. Click Update, select Download New and click 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, click 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 (www.hp.com/go/bizsupport). Installation utilities and instructions for creating a BIOS floppy disk are provided with the updates.

HP Omnibook XE4100/XE4500 Removal and Replacement 2-37

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 Omnibook model you are repairing. The program does not verify the Omnibook 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.

Support by Authorized Service Providers

In the U.S., support of Omnibook XE4000 series notebook computers by Authorized Service Providers (ASPs) is a purchasable option. Standard predefined models and standard special models do not include ASP support. The sales 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.

Figure 3-1. Basic Troubleshooting Steps

3-2 Troubleshooting and Diagnostics HP Omnibook XE4100/XE4500

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.

Important

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

Troubleshooting the Problem

Record pertinent information about the notebook:

• Model and serial number.

• Operating system and version.

• Software version (stored in 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.

• Consider Causes.

If there are multiple symptoms, separate them into distinct problems.

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’s components using automatic



and interactive tests, and is your primary troubleshooting tool. Other tools include the poweron self-test, WMI/Toptools (if installed), the BIOS Setup utility, and the Sycard PCCtest. Table 3-2 on page 3-5 shows how you can use these tools to isolate the cause of the notebook’s problem.

The troubleshooting suggestions on page 3-6 include general suggestions for repairing



notebooks that show specific failure symptoms.

HP Omnibook XE4100/XE4500 Troubleshooting and Diagnostics 3-3

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:

3-16 Troubleshooting and Diagnostics HP Omnibook XE4100/XE4500

Diagnostic Tools

This section describes the following diagnostic tools you can use for troubleshooting and repairing the notebook:

• Notebook e-Diagtools diagnostic program (below).

• Power-on self-test (page 3-19).

• Sycard PCCtest 450 PC card (page 3-25).

• Windows Management Instrumentation (page 3-26).

• BIOS Setup utility (page 3-27).

e-Diagtools Diagnostic Program

The hardware diagnostic programs provide two levels of testing:

• User-level testing using a basic hardware test.

• Advanced testing using individual hardware tests.

The tests are designed to run after the system reboots, so that the notebook will be in a predictable state during the tests. The tests are non-destructive, and are intended to preserve the state of the notebook. The notebook reboots when you exit the program so drivers can be loaded.

Updating e-Diagtools

You can download the latest version of e-Diagtools using e-Diagtools for Windows.

HP Omnibook XE4100/XE4500 Troubleshooting and Diagnostics 3-17

Running e-Diagtools

The following procedure describes how to run e-Diagtools. The individual steps might differ slightly for different versions of e-Diagtools.

1. Click Start, Turn Off Computer (or Shut Down), Restart.

2. When the HP logo appears, press F10 to start the diagnostic test.

The first time you run the program, you are prompted to select the language for the program.

3. When the menu appears, press F2 to run e-Diagtools.

4. When the Configuration Description appears, check the list of detected hardware.

5. Run the basic test. Press F2 to start the basic hardware test. The results appear when the test is

complete.

6. If you intend to exit without running the advanced tests, press F4 to view the Support Ticket. Press

F3 to exit e-Diagtools.

7. Optional: run the advanced tests. Press F2 to open the advanced test screen.

8. Use the arrow keys and ENTER to select the test you want to run. Tests are listed only for detected

hardware.

9. Press F2 to run the selected tests and add the results to the Support Ticket.

10. After each run, press F2 to return to the advanced test screen, or press F4 to view the Support

Ticket.

11. Exit.

Press F3 and then any key to exit and reboot.

12. Optional: open the Support Ticket. In Windows, click Start, All Programs (or Programs),

Hewlett-Packard, Notebook, HP e-Diagtools, e-Diagtools for Windows.

13. Click View to display the Support Ticket.

14. To add information about your problem, click Comments, type the information, and then click OK.

e-Diagtools for Windows can also update the version of e-Diagtools on your notebook’s hard disk. In e-Diagtools for Windows, use the e-Diagtools menu.

If you have trouble running e-Diagtools diagnostics from the hard disk, you can also run it from the Recovery CD or DVD. Boot from the CD or DVD and select the diagnostics option.

3-18 Troubleshooting and Diagnostics HP Omnibook XE4100/XE4500

Interpreting the Results

The e-Diagtools diagnostic program returns test groups, error codes, and suggestions for repair and/or follow-up actions. The basic hardware test shows a recommended replacement part.

To help interpret the results of the e-Diagtools tests, refer to the following:

• e-Diagtools Support Ticket on page 3-18.

• Replaceable Module Diagram on page 1-14

• Functional Structure Description on page 1-15

This combined information should enable you to determine which of the notebook’s components require service.

HP Omnibook XE4100/XE4500 Troubleshooting and Diagnostics 3-19

Power-On Self-Test

Note

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

When the notebook boots, its system BIOS runs a series of initialization routines and diagnostic tests called POST (Power-On Self-Test). The BIOS will not boot the notebook’s operating system if the system memory, CPU, DMA, or interrupt controller fails the POST diagnostic tests. POST indicates progress by a sequence of codes; if an error occurs, the BIOS displays a message and/or issues a beep code.

Note that not all POST messages indicate a failure in the notebook—some messages are for information only. You should not necessarily interpret the failure of one or more POST tests as a hardware, software, or firmware failure. If POST displays an error message or issues a beep code indicating an error, confirm the problem using other diagnostic tools.

First, confirm the failure by performing a “clean” boot, as described below. Note that if the notebook fails to restart with a clean boot, it requires repair.

1. Remove all accessories, including SDRAM modules, port replicator, PC cards, printer, external

monitor, pointing device, and keyboard.

2. Provide “clean” AC power—no auto adapter or unusual AC adapter configuration.

3. Press the reset button to return the notebook to a known state.

4. Press the power button to start the notebook.

If the BIOS detects a terminal error condition, it halts POST after issuing a beep code and/or displaying a message (see the following table). The beep code indicates the POST routine in which the terminal error occurred.

Sycard PCCtest 450/460 PC Card (Optional)

The PCCtest 450 and 460 cards (version 1.05) from Sycard Technology are the only recommended diagnostic tools that test the functionality of the PCMCIA slots using a PCMCIA card. Each is a Type II PC card that works with test software to exercise PCMCIA functions. (For details, see the Sycard Technology web site: http://www.sycard.com).

The PCCtest product contains these components:

• PCCtest 450 or 460 (revision 1.05) PC card.

• PCCtest 450/460 software disk. (Software updates are available at the Sycard Technology web

site.)

• Configuration headers (PC card/16-bit and CardBus/32-bit) that attach to the card.

You will also need a CardBus extender card (such as the Sycard PCCextend 70) to avoid wear on the Sycard PCMCIA connector.

Use the following tests to check the function of the notebook’s PCMCIA slots. See the Sycard documentation for details about running the tests.

Windows Management Instrumentation (WMI)

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

Installing the WMI Package

The WMI package is either preinstalled on the notebook’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 WMI preloaded on the hard disk:

1. Start Windows, if it is not already running.

2. Click Start, Programs (or All Programs), Hewlett-Packard, HP Toptools Agent, Setup.

Using WMI

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

• A README.TXT file: click Start, Programs, Hewlett-Packard, HP Toptools Agent, Read me.

• A Windows online help file describing Hewlett-Packard’s implementation of WMI (group and

attribute definitions): click Start, Programs Hewlett-Packard, HP Toptools Agent, HP Toptools Help.

Uninstalling the WMI Package

1. Click Start, Programs (or All Programs), Hewlett-Packard, HP Toptools Agent, Uninstall WMI.

2. Restart the notebook.

3-26 Troubleshooting and Diagnostics HP Omnibook XE4100/XE4500

BIOS Setup Utility

The BIOS Setup utility provides access to the notebook’s basic configuration settings. It is independent of the operating system.

Running the BIOS Setup Utility

1. Close all applications, then restart the notebook: click Start, Turn Off Computer, Restart. (If

necessary, you can press Ctrl+Alt+Del to restart.)

2. When the HP logo appears, press F2 to enter the BIOS Setup utility.

3. The pointing devices are not active in BIOS Setup, so you will need to use the keyboard to

navigate:

• Press the LEFT and RIGHT arrow keys to move among menus.

• Press the UP and DOWN arrow keys to move among parameters in a menu.

• Press F5 or F6 to move through values for the current parameter, or press Enter to change a

setting.

4. After you select the options you want, press F10 or use the Exit menu to exit BIOS Setup.

If the settings cause a conflict between devices during reboot, the system prompts you to run BIOS

Setup, and marks the conflicting settings.

Note

The listings in the following table are for the initial XE4100/XE4500 BIOS release, and might differ somewhat for other models.
