Reassembly Procedure  
Note: Reprogramming the BIOS IC  
A new BIOS IC contains only enough basic programming to enable the notebook to boot. After  
installing a new motherboard, you must reprogram the BIOS IC, preferably with the latest BIOS—  
see page 2-29.  
1. Transfer the following components from the old motherboard onto the new motherboard:  
• SDRAM module  
• speaker assembly  
• display interface PCA  
• volume PCA  
• CPU module  
• PCMCIA socket  
• mini-PCI card #1 (if present)  
• mini-PCI card #2 (if present)  
2. Follow the reassembly notes in the section entitled “Removing the Motherboard or Bottom Case”  
on page 2-25.  
Note: After Replacing the Motherboard  
After replacing the motherboard, you must use the Service Utility floppy disk to store the system data  
and display information in the EEPROM on the new motherboard.  
1. Connect a floppy disk drive module: insert the module into the notebook, or connect it to the  
computer using an F2008 external floppy drive cable.  
2. Plug in an AC adapter.  
3. Insert the Service Utilities floppy disk in the floppy drive.  
4. Turn on the computer.  
5. If you hear 5 beeps, press F1 to update the display data stored on the motherboard. Let the  
computer reboot and go to the next step.  
6. Select the Serial Number option from the boot menu.  
7. If you successfully stored system data on the floppy disk before removing the old motherboard,  
type A for the automatic update. This restores the old system data on the new motherboard.  
If you did not store system data, type M for the manual update option. Enter the serial number from the  
bottom of the unit—you may have to contact an HP support center to do this.

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 may 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.  
Caution  
The BIOS update completely replaces the previous BIOS, so follow the directions in this section  
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.  
Using a BIOS Floppy Disk  
Use a BIOS floppy disk to update the notebook’s BIOS as follows:  
1. Undock the notebook if it is docked, and remove any PC cards from it.  
2. Connect a floppy disk drive module: insert the module into the notebook, or connect it to the  
notebook’s parallel port using an F2008 external floppy drive cable.  
3. Connect the AC adapter to the notebook.  
4. Insert the BIOS floppy disk into the floppy drive.  
5. Turn on the notebook. When the notebook boots, follow the instructions that appear on screen.  
6. When the process is completed, press the system-off switch to reset the system.  
BIOS updates are also 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.  
Using e-DiagTools for Windows  
If the notebook allows you to boot into Windows, you may be able to use e-DiagTools for Windows to  
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 PC 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), 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 is completed, press the system-off switch to reset the system.

Using a Crisis Recovery Floppy Disk  
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.  
Caution  
Make sure to use the correct BIOS Crisis Recovery floppy 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 Crisis Recovery disk in the floppy disk drive.  
2. Turn on the computer and allow it to boot from the floppy disk.  
If the notebook does not turn on at all, do the following to boot from the floppy disk:  
a. Unplug the AC adapter.  
b. Press and hold Fn+B.  
c. Plug in the AC adapter.  
d. Release Fn+B.  
If the notebook will not boot from the floppy, try plugging the boot-block jumper into the

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 includes additional criteria for determining customer abuse to specific parts of the unit.  
Important  
Parts damaged by customer abuse are not covered by the warranty.  
Troubleshooting the Problem  
Record pertinent information about the unit:  
• 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. 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’s components using automatic  
and interactive tests, and will be 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 3-1 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  
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 unit 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 3-19).  
–and–  
• Function Tests. Run tests that check the repaired function, such as those in e-Diagtools (page 3-  
19).  
–and–  
• Failed Tests. Run any other tests that failed during troubleshooting.

Diagnostic Tools  
This section describes the following diagnostic tools you can use for troubleshooting and repairing the  
Omnibook:  
• Omnibook e-Diagtools diagnostic program (below).  
• Power-on self-test (page 3-22).  
• Sycard PCCtest 450 PC card (page 3-27).  
• Windows/Desktop Management Interface (page 3-28).  
• BIOS Setup utility (page 3-29).  
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.  
Figure 3-2. Diagnostic Screens — Basic and Advanced  
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.

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 will show a recommended replacement part, while the  
advanced tests also provide more detailed error descriptions.  
To help interpret the results of the e-Diagtools tests, refer to the following:  
• e-Diagtools online help  
• 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.

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 certain  
components fail 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: If the notebook fails to  
restart with a clean boot, it requires repair.  
1. Remove all accessories, including SDRAM modules, floppy drive, 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 system-off switch to return the notebook to a known state.  
4. Press the blue sleep 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 (WMI) is basically a set of rules for accessing  
information about a computer. 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 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 WMI Package  
The WMI 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 WMI preloaded on the hard disk:  
1. Start Windows, if it is not already running.  
2. Click Start, Programs (or All Programs), HP Toptools, Setup.  
Using WMI  
For a complete description of how to use WMI, see the following documentation provided with the  
computer:  
• A README.TXT file: click Start, Programs, HP Toptools, Read me.  
• A Windows online help file describing Hewlett-Packard’s implementation of WMI (group and  
attribute definitions): click Start, Programs, HP Toptools, HP Toptools Help.  
Uninstalling the WMI Package  
1. Click Start, Programs (or All Programs), HP Toptools, Uninstall WMI.  
2. Restart the notebook.

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, Shut Down (Windows 2000) or Turn  
Off Computer (Windows XP), 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.

Updating the Notebook’s BIOS  
Hewlett-Packard may from time to time provide updates to the notebook’s BIOS. Use e-DiagTools for  
Windows to download and install these BIOS updates as needed—see “Using e-DiagTools for  
Windows” on page 2-29.  
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 PC 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), 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 is completed, press the system-off switch to reset the system.  
BIOS updates are also 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.

Reference Information  
This chapter includes the following reference information:  
• Password removal policy.  
• Display quality statement.  
Password Removal Policy  
If the user forgets the system password, the user calls Technical Support to determine the proper  
removal procedure. The user must provide proof of ownership, and the Omnibook must be operated  
during the procedure.  
The password removal procedure is protected as HP Company Private information. There are a  
restricted number of locations that can perform password removal. It may not be disclosed or  
distributed outside those locations.  
Password removal is strictly controlled. Hewlett-Packard and authorized support providers must  
ensure with written evidence that the Omnibook being “cleansed” is actually in the possession of the  
unit’s actual and current owner. This requires a sales receipt showing the unit serial number and  
owner’s name, or a written statement from the owner attesting that he or she is the owner of the unit.  
The statement can be a fax copy of the document. The fact that the unit is in the hands of an HP  
representative on behalf of the customer is not evidence of ownership. In addition, HP will not remove  
the password of a unit for any non-owner, even if it is requested by law enforcement agencies. If you  
receive such a request, you should notify management and HP Corporate Legal immediately. (These  
requests may require a court order prior to our participation.)  
Further, the entity removing the password must log the name, serial number and date of the removal,  
and file the written backup with the log. The log and backup are subject to standard record retention  
process and review.  
The final issue relating to removal of passwords is that HP cannot provide information to users that  
would assist them in improperly removing a password and opening a unit.

Hewlett-Packard Display Quality Statement  
TFT display manufacturing is a highly precise but imperfect technology, and manufacturers cannot  
produce large displays that are cosmetically perfect. Most, if not all, TFT displays exhibit some level  
of cosmetic imperfection. These cosmetic imperfections may be visible to the customer under varying  
display conditions, and can appear as bright, dim, or dark spots. This issue is common across all  
vendors supplying TFT displays in their products and is not specific to the HP Omnibook display.  
HP Omnibook TFT displays meet or exceed all HP standards for cosmetic quality of TFT displays.  
HP does not warrant that the displays will be free of cosmetic imperfections. TFT displays can have a  
small number of cosmetic imperfections and still conform to HP’s cosmetic quality specifications.  
Here are some guidelines for determining what action to take on customers’ complaints of cosmetic  
imperfections in their TFT displays:  
1. View the unit under the customer’s normal operating conditions.  
This means that if the customer uses the unit predominately in DOS, in Windows, or in some  
other application or combination of applications, you should make the determination under those  
same applications. Self test is not a normal operating condition and is not a sufficient tool for  
interpreting display quality.  
2. Use the table below to determine whether the display should be considered for replacement.  
These are the only conditions in this guideline that may call for a replacement due to a defect in  
material or workmanship based on the HP Limited Warranty Statement.  
3. If a display is considered for replacement, make sure the customer understands that cosmetic  
variations may also exist on the replacement display, and may require the customer to use a work-  
around to obscure the cosmetic imperfection.  
4. Customers with cosmetic-based complaints that do not conform to the above conditions and tests  
will not normally be considered for display replacement. The HP-responsible person working with  
the customer should identify work-arounds that are reasonable and appropriate for the individual  
customer. Customers who must have a more perfect display solution should consider switching to  
an Omnibook with a DSTN display.  
We expect that over time the industry will continue to produce displays with fewer inherent cosmetic  
imperfections, and we will adjust our HP guidelines as these improvements are implemented.
