Internal Design

The motherboard PCA is the central component of the OmniBook design. It plays a role in virtually all
system functions. The CPU module (MMO) and all other subsystems connect to the motherboard.

The following figure shows the connections among the replaceable electrical modules. As a substitute
for a functional block diagram, see the table on page 1-10—it lists the roles the replaceable modules
play in each of the functional subsystems.

Reassembly Notes

Note: Installing a New Motherboard

• Transfer these PCAs from the old motherboard to the new one:

LVDS PCA (secure it with one 5 mm screw on the right side).
Caution: Do not use a longer screw—it will damage the motherboard.

Audio PCA (on the underside).
RAM board, if present (on the underside).

• Store the serial number electronically in the new motherboard—see the steps below.

Note: Installing a New Bottom Case

• Transfer these parts from the old bottom case to the new one:

Lock plate (see Figure 2-20).
Plastic parts (I/O door, RAM cover).

• Install a new regulatory label on the bottom case—see the steps below.

• Check that the audio PCA has two rubber bumpers attached to the board directly behind the two

connectors.

• Check that the audio PCA is securely attached to the underside of the motherboard before installing

the motherboard. The audio PCA can work loose if you flex the motherboard excessively.

• Place the audio jack holder onto the audio jacks before you lower the motherboard into the case.

• Raise the front edge of the motherboard only high enough for the PCMCIA pushbuttons to clear the

bottom case. Work the I/O bracket into the back of the bottom case, then lower the front edge into
the case.

• Do not install screws into the motherboard next to the ac adapter socket or next to the plug-in

module socket. (See Figure 2-20.)

Caution

When installing the CPU module onto the motherboard, press on the white target (Figure 2-19).
Otherwise, you could damage pressure-sensitive components.

• The two screws at the front-underside of the bottom case are the shortest screws—only 3 mm long.

Caution

Insert the back end of the USB PCA into the case first, then carefully align the connector before
pressing it onto the motherboard. Take care not to damage the connector pins.

• Before you install the top case and heat sink assembly, make sure you have installed only two

screws in the CPU module—the two at the front corners. (You install the remaining screw after you
install the heat sink.)

2-24 Removal and Replacement HP OmniBook 3000

Storing the Serial Number Electronically

1. Exit Windows and boot to a DOS prompt.

2. Run ESN.EXE from one of these sources:

On a factory software installation, change to the \OMNIBOOK directory and type esn at the
prompt.

Otherwise, copy \Omnibook\Drivers\Hputils\Esn.exe from the OmniBook 3000 Recovery CD,
then run it on the OmniBook.

3. When prompted, type the serial number shown on the bottom of the case. (If a serial number has

already been stored, you must call an HP support center to change it.)

Installing a New Bottom-Case Label

1. Attach a regulatory label in the recess in the bottom case. The bottom of the label goes toward the

front of the case.

2. Looking at the serial number on the unit’s original bottom case, create a replacement serial number

label. A separate Service Note gives details about equipment, software, and label material.

3. Attach the serial number label to the bottom area of the regulatory label.

HP OmniBook 3000 Troubleshooting and Diagnostics 3-1

Troubleshooting

The suggestions in this section can help isolate and repair the cause of a problem. To ensure quality
repair, HP recommends that you follow the basic troubleshooting steps shown in the illustration below.

Check the customer's description
of the problem and any supporting
information.

Try to duplicate the customer's
problem.

Troubleshoot the problem using

- Troubleshooting suggestions.

- Diagnostic tools.

Verify the repair by testing the
functionality of the complete unit .

Figure 3-1. Basic Troubleshooting Steps

Troubleshooting the Problem

Record pertinent information about the unit:

Model and serial number.
Operating system and version.
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.

3-2 Troubleshooting and Diagnostics HP OmniBook 3000

• Consider Causes. Keep in mind possible causes for each problem, such as the ones listed in the

tables below. Use the diagnostic tools to help find possible causes and repair the problem.

The first table below lists general guidelines for repairing units with certain failure symptoms. The

suggested order of investigation is not mandatory. The second table (page 3-8) shows how you can
use the different diagnostic tools to isolate the cause.

Swapping easily replaced modules with known-good modules is an ideal way to isolate the cause down
to the module level. It is rare for more than one module to be responsible for one failure symptom.
Therefore, replacement of more than one module for a particular symptom should be the exception
rather than the normal expectation.

After replacing a module, it is normal for the unit to be in a confused state and lock up when power is
applied. If this occurs, press the system-off button to restart the computer in a known state.

• OmniBook hardware diagnostic program (page 3-10).

• Power-on self-test (page 3-15).

• Sycard PCCtest 450 PC Card (page 3-17).

• Desktop Management Interface (page 3-18).

• BIOS Setup utility (page 3-20).

OmniBook Diagnostic Program

The OmniBook hardware diagnostic program provides two levels of testing:

• User-level testing using the basic hardware test.

• Advanced testing using the individual hardware tests.

Figure 3-2. OmniBook Diagnostic Screens — Basic and Advanced

The tests are designed to run after the system reboots. This ensures that the computer will be in a
predictable state, so the diagnostic program can properly test the hardware components. The tests are
non-destructive and are intended to preserve the state of the computer. The OmniBook reboots when you
exit the program so drivers can be loaded.

Creating a Diagnostic Disk

After inserting a formatted floppy disk in the floppy drive, do one of the following to create a diagnostic
floppy disk:

• On a factory software installation, run diaginst from the \Dmi\Hpdiags directory on the hard disk.

• On any computer, run diaginst from the \Omnibook\Dmi\Hpdiags directory on the

OmniBook 3000 Recovery CD.

• On any computer, download the diagnostic software package from the OmniBook website (see page

vi), run this file to unpack the files, then run diaginst a: to create the diagnostic disk.

3-10 Troubleshooting and Diagnostics HP OmniBook 3000

Running the Diagnostic Test

1. Insert the diagnostic disk in the floppy drive.

2. Reboot the OmniBook.

3. Go through the first several screens.

4. When the hardware detection finishes, check the list of detected hardware. The following
information and devices should be listed if applicable:

Product name Cache memory Floppy drives

Serial number Main memory IDE drives
BIOS version Graphics adapter SoundBlaster audio device
Processor type Display name

Note

If any such device is present but not detected, or if its test fails, it may be configured incorrectly
in the BIOS Setup utility (page 3-20). You can confirm the problem by running BIOS Setup and
restoring the default settings.

5. Optional: When the hardware detection finishes, press F4 to save system information in the Support
Ticket log file, HPSUPPT.TXT.

6. Run the basic test. When prompted, press F2 to start the basic hardware test.

7. Optional: When the test finishes, press F4 to save system and test information in the Support Ticket
log file, HPSUPPT.TXT.

8. Run the advanced tests. When prompted, press F2 to open the advanced test screen.

9. Select and run the appropriate tests. Tests are dimmed if no such hardware is detected. Press the
following keys to run tests:

ENTER Runs the highlighted test.

F5 or SPACE Marks or unmarks the highlighted test.
F6 Marks or unmarks all tests in the current menu.
F7 Marks or unmarks all tests in all menus.
Batch menu, Run Batch Test, ENTER runs all marked tests.

If any test fails, the error is logged (error code and description) and displayed temporarily (error

code). If several errors occur, look for patterns that might indicate a common cause. See the table
on page 3-12 for repair suggestions. Consider these suggestions in combination with other
troubleshooting information.

10. Exit. When you are finished running tests, remove the diagnostic disk, then press ESC to exit and
reboot.

11. Optional: Check the log. On any computer, open the HPSUPPT.TXT log file on the diagnostic
disk using Notepad or other text editor. It contains a list of all test results and errors.

Note that the serial and parallel port tests are more thorough if you connect a loopback connector to the
port before running the test for that port. See the wiring diagrams below.

Power-On Self-Test

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 system
memory, the CPU, DMA, or the interrupt controller fails the POST diagnostic tests. POST progress is
indicated by a sequence of codes. If possible, error messages are displayed. No beep codes are sounded.

You should not interpret the failure of one or more POST tests as a hardware, software, or firmware
failure. First, confirm the failure with a “clean” boot:

• Remove all accessories, including RAM boards, floppy drive, port replicator, 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 button to start from a known state.

If the computer fails to boot with a clean boot, it requires repair. If an error message is displayed,

confirm the problem using other diagnostic tools.

The following tables list error codes and error messages. Not all POST messages indicate a hardware,
software, or firmware failure—some messages are informational messages.

Sycard PCCtest 450 CardBus Card (Optional)

The PCCtest 450 CardBus Card available from Sycard Technology is an optional diagnostic tool. It is
the only recommended tool that tests the functionality of the PCMCIA slots. It is a Type II CardBus
Card that works with compatible test software to exercise PCMCIA functions. The PCCtest 450 product
contains these components:

• PCCtest 450 CardBus Card.

• PCCtest 450 software disk. (Software updates are available at the Sycard Technology website,

http://www.sycard.com.)

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

You will also need:

• CardBus extender card to avoid wear on the Sycard PCMCIA connector. The Sycard

PCCextend 70 extender card is an example.

The Sycard PCCtest 450 provides the following tests. See the Sycard documentation for details about
running the tests.

Desktop Management Interface (DMI)

The Desktop Management Interface (DMI) is basically a set of rules for accessing information about a
personal computer. Using DMI, an application program can determine, for example, which hardware
and software components are present in a personal computer, the operating system that is being used,
and the number of accessory board slots that are available. Using the DMI interface, a local or remote
application program can check what hardware and software components are installed on your computer,
how well they are working, and whether any needs replacing. All this information is stored in a special
Management Information Format (MIF) file, installed on each personal computer as part of the DMI
package.

Installing the DMI Package from Windows 95

The DMI package is included with the OmniBook, but it must be properly installed before it can be
used. The following steps explain how.

To install the DMI preloaded on the hard disk:

1. Start Windows 95, if it is not already running.

2. Click Start, Programs, HP DMI, Setup.
To install the DMI from floppy disks or from the OmniBook 3000 Recovery CD:

1. For floppy disks, copy the DMI software from the \omnibook\drivers\win95\dmi directory of either
the hard disk or Recovery CD to two floppy disks (copy the contents of the \disk1 subdirectory to
disk #1 and the contents of the \disk2 subdirectory to disk #2).

2. Start Windows 95, if it is not already running.

3. Insert disk #1 into the floppy drive, or insert the Recovery CD into the CD-ROM drive.

4. Select and run the SETUP program from floppy disk #1 or from the
\omnibook\drivers\win95\dmi\disk1 directory on the CD.

Uninstalling the DMI Package from Windows 95

1. Click Start, Programs, HP DMI, Uninstall DMI.

2. Reboot the PC.

Using the DMI Interface

For a complete explanation of how to fully take advantage of DMI, the following documentation is
provided with the OmniBook:

• A README.TXT file.

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

attribute definitions). Since not all Hewlett-Packard enhanced features are supported on all models,
this document also describes any restrictions that apply.

Description of DMI

The Desktop Management Interface (DMI) is the result of the efforts of the Desktop Management Task
Force (DMTF). This task force was founded in 1992 by a group of leading computer manufacturers,
including Hewlett-Packard, to define a standard method of managing the physical and logical
components of personal computers.

(identifying a computer using a unique string of characters).

For full details of the structure of the MIF file, including an explanation of the meaning of the fields of
groups and attributes and how to write an application program that accesses this information, you can
access the DMTF FTP server ftp.dmtf.org or the DMTF web pages at the http://www.dmtf.org.

Contents of the DMI Package

The DMI software and associated documentation is supplied either preinstalled on the OmniBook’s hard
disk drive or on two floppy disks. The contents of the package are the same in both cases.

Since the information accessed by the DMI software is specific to a particular computer, it must be
installed on each computer separately. The DMI package included with the OmniBook can be used only
with the OmniBook.

The following software is supplied with the DMI package:

• A Microsoft Windows utility, SETUP.EXE, to install and initialize the DMI software.

• A Windows utility, HP TopTools. After DMI is installed, this utility can be used to display

information about the computer through the DMI.

• A Management Information Format (MIF) file. This file contains information about everything on

the computer that can be controlled using DMI facilities, and is initialized during installation.

• A component code, identifying the version of MIF file to use for specific models of HP OmniBook

computers.

• Windows-compatible DMTF Service Layer software, which controls access to the DMI.

• A client agent. The HP Remote DMI Agent is a DMI application and also a network server-side

stream-based application. The Remote Agent is listening for Remote Application connection
requests. If the main window of the Remote Agent is hidden, then no icon will appear on the screen
when it is running.

The following illustration shows a representation of several components of the DMI package.

Reference Information

This chapter includes the following reference information:

• Password removal policy.

• TFT display quality statement.

Password Removal Policy

If the user forgets the system password, the user calls Technical Support to determine the proper
removal procedure. This may require sending the unit to a Hewlett-Packard repair center.

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.)

5

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.

HP OmniBook 3000 Reference Information 5-1

Hewlett-Packard TFT Display Quality Statement

TFT display manufacturing is a high precision but imperfect technology and manufacturers cannot
currently produce large displays that are cosmetically perfect. Most, if not all, TFT displays will 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 TFT manufacturer’s standards for cosmetic quality of
TFT displays. HP does not warrant that the displays will be free of cosmetic imperfections. TFT

displays may have a small number of cosmetic imperfections and still conform to the display
manufacturer’s cosmetic quality specifications.

Here are some guidelines to use in determining what action to take on customers’ complaints of
cosmetic imperfections in their TFT displays:

1. The unit should be viewed in the customer’s normal operating condition.
This means if the customer uses the unit predominately in DOS, in Windows, or in some other

application or combination of applications, that is where you should make the determination. Self
test is not a normal operating condition and is not a sufficient tool to interpret 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, it should be clear to the customer that cosmetic variations
on the replacement display may also exist, and may require the customer to use a work-around to
obscure the cosmetic imperfection.

4. Customers with cosmetic-based complaints only, that do not conform to the above conditions and
tests will not normally be considered for display replacement. It will be left to the judgment of the
HP-responsible person working with the customer, to 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 over time that the industry will continue to improve in its ability to produce displays with
fewer inherent cosmetic imperfections, and we will adjust our HP guidelines as the improvements are
implemented.
