The top shield for a 9.5-mm drive
has spacers.
HDD Case (Kit)
(includes M3×5mm screws)
Figure 2-4. Installing a Hard Drive in the Case
Reassembly Notes
Caution
• Use a HDD case kit that is compatible with the thickness of the drive, 9.5 mm or 12.7 mm.
The 9.5-mm drive requires spacers inside the top shield.
• Install the metal top shield that is included with the HDD case. If an older HDD case does not
have a top shield, you must install a newer HDD case if the drive is a Toshiba drive—
otherwise, drive performance may be reduced by magnetic interference.
• Do not cover the vent hole in the top surface of the hard drive or in the case. If you cover the
hole, the hard drive could fail prematurely.
• Depending on the manufacturer of the replacement drive, the hole placement for the four screws
may vary.
Important
If you are installing a new hard drive, you should create a Hibernate partition on the drive before
loading any software—see the steps below.
Creating a Hibernate Partition
1. If you do not have an OmniBook Recovery CD and internal CD-ROM module for the computer
model you are repairing, create a Support Utility floppy disk now.
After inserting a formatted floppy disk in the floppy drive, do one of the following:
¨
On a factory software installation, click Start, Programs, OmniBook, Create Support Utility
Disk.
2-6Removal and ReplacementHP OmniBook 2100/3000/3100
¨
On any computer that has a CD-ROM drive, run makesupp from the
\Omnibook\Drivers\Hputils directory on the OmniBook Recovery CD.
¨
On any computer with World Wide Web access, download the Support Utility software
package from the OmniBook website (see page vi). Follow the instructions provided.
2. Insert the Recovery CD in the CD-ROM drive—or insert the Support Utility disk in the floppy
drive.
3. Reboot the computer. If you are using the Recovery CD, press ESC during reboot if the
OmniBook screen appears, ESC to display the boot-device menu, then select the CD-ROM drive
as the boot device.
4. When prompted, select “Create Hibernate Partition.”
OmniBook 2100/3100: We recommend that you create a partition the same as the factory setup—
288 MB for a Pentium II CPU, or 192 MB for a Pentium CPU (160 MB is acceptable if the
motherboard has only one RAM slot).
OmniBook 3000: We recommend that you create a 144-MB partition, the same as the factory
setup.

Reassembly Notes
Caution
Be sure to replace the motherboard, thermal kit (pad and spacer), or heatsink with parts that are
compatible with the CPU module. Components may be damaged if compatible parts are not used.
See the table starting on page 4-3.
• Before you install the top case and heatsink, make sure the left-rear screw is not installed in the
CPU module. (You install it after you install the heatsink.)
• Make sure the IR/icon cable and speaker cables are properly routed and restrained.
• Place the top case over the front latch but tilted up at the back, then pull forward and down along
the front edge until the snaps lock. Finally, seat the back edge over the hinge brackets.
• Route the speaker/touch-pad cable so it does not overlap the CPU module or PCMCIA housing.
(See Figure 2-17.) (Service notes 3000-09, 2100-05, 3100-05.)
• Before installing the heatsink, make sure a rubber spacer is stuck to the back-right corner of the
CPU module. If the thermal pad on top of the CPU is damaged, replace it. (Both parts are
included in the CPU thermal kit.) (See Figure 2-17.)
• When installing the heatsink, remember to plug in the fan cable, and make sure it does not overlap
the CPU module. (See Figure 2-17.)
Caution

Reassembly Notes
Note: Installing a New Motherboard
• Caution: Replace the motherboard with one containing a BIOS IC that is compatible with the
CPU module—see the table starting on page 4-3. Alternatively, reuse the BIOS IC from the
original 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).
• Reprogram the BIOS IC—see the note below.
• 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:
Plastic parts (I/O door, RAM cover).
Lock plate and IR lens, if not included with new case (see Figure 2-21).
• Install new regulatory and serial-number labels 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 cover 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 2-21.)
Caution
When installing the CPU module onto the motherboard, press it down above the connectors—but
do not push on large components. Otherwise, you could damage pressure-sensitive components
on the module.
• 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.
HP OmniBook 2100/3000/3100Removal and Replacement2-27
• Before you install the top case and heatsink, check the screw holes at the front corners of the CPU
module:
¨
If two screws were previously installed, install them again. (You install the back-left screw
after you install the heatsink.)
¨
If no screws were installed in the front corners of the CPU module, do not install screws
there—the heatsink holds the CPU module. (You install the back-left screw after you install
the heatsink.)
Note
If you installed a new motherboard with a new BIOS IC, the IC contains only enough basic
programming to boot the OmniBook. After installing the IC, you must reprogram it. HewlettPackard prefers that you program the IC with the latest BIOS—follow the directions carefully. You
can download it from the OmniBook website (see page vi).
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\Drivers\Hputils directory
(OmniBook 2100/3100) or \Omnibook directory (OmniBook 3000) and type
esn at the
prompt.
¨
Otherwise, copy \Omnibook\Drivers\Hputils\Esn.exe from the OmniBook Recovery CD, then
run it on the OmniBook.
3. Store the serial number:
¨
If you are prompted for the serial number, 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 New Regulatory and Serial-Number Labels — OmniBook 2100/3100
If you do not have a master template for creating serial number labels, get a copy from the Reseller
website (see page vi) under Product Support Information in the Service and Support Library.
1. Attach the regulatory label in the recess in the bottom case.
2. Using any PC connected to a laser printer, create a new Word document using master serial label
template, enter the serial number and product number from the old serial label, and print the new
label on plain white paper. The new label does not have barcodes.
3. Carefully cut out the new serial label just inside the border and place it into the inner recess in the
bottom case. The bottom of the label goes toward the front of the case.
4. While holding the paper label in place, attach a serial label overlay into the outer recess. It covers
and protects the serial label.

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

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.
3-2Troubleshooting and DiagnosticsHP OmniBook 2100/3000/3100
• Separate Problems. If there is more than one symptom, 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 OmniBook diagnostic program is the primary troubleshooting tool—it tests most
components using automatic and interactive tests. The table on page 3-4 shows how you can
use the different diagnostic tools to isolate the cause.
¨
The troubleshooting suggestions on page 3-5 include general suggestions for repairing units
with certain failure symptoms.
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.
Verifying the Repair
Before returning the repaired unit to the customer, verify the repair by running the following tests:
Basic Diagnostic Test. Run the basic test of the OmniBook diagnostic program (page 3-12).
•
–and–
Function Tests. Run tests that check the repaired function, such as in the OmniBook diagnostic

Diagnostic Tools
This section describes the following diagnostic tools you can use for troubleshooting and repairing the
OmniBook:
• OmniBook hardware diagnostic program (page 3-12).
• Power-on self-test (page 3-17).
• Sycard PCCtest 450 PC Card (page 3-17).
• Desktop Management Interface (page 3-21).
• BIOS Setup utility (page 3-23).
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 an OmniBook with a factory software installation, run
directory on the hard disk.
–or–
For an OmniBook 2100/3100 with TopTools installed, use the DiagTools page to create the disk.
3-12Troubleshooting and DiagnosticsHP OmniBook 2100/3000/3100
diaginst from the \Dmi\Hpdiags
• On any computer with a CD-ROM drive, run diaginst from the \Omnibook\Drivers\Hputils
directory (OmniBook 2100/3100) or \Omnibook\Dmi\Hpdiags directory (OmniBook 3000) on the
Recovery CD for the computer model you are repairing.
• On any computer with World Wide Web access, download the diagnostic software package from
the OmniBook website (see page vi), run this file to unpack the files, then run
diaginst to create
the diagnostic disk.
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 nameMain memoryGraphics adapter
Processor typeIDE drivesSerial ports
BIOS versionFloppy drivesParallel port
Serial numberKeyboardAudio device
Cache memory
Note
If a device is not detected or fails its test below, it may be configured incorrectly in the BIOS Setup
utility (page 3-23). You can confirm the problem by running BIOS Setup and restoring the default
settings.
5. Run the basic test. Press F2 to start the basic hardware test.
6. If you intend to exit without running advanced tests, press F4 to save system and test information
in the Support Ticket log file, HPSUPPT.TXT. Then remove the diagnostic disk and press F3 to
exit.
7.
Run the advanced tests. Press F2 to open the advanced test screen.
8. Select and run the appropriate tests. Tests are not listed if no such hardware is detected. Press the
following keys to run tests:
ENTERRuns the highlighted test.
F5 or SPACEMarks or unmarks the highlighted test.
F6Marks or unmarks all tests in the current menu.
F7Marks or unmarks all tests in all menus.
F10Runs 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 3-14 for repair suggestions. Consider these suggestions in combination with other
troubleshooting information.
9. When you are finished running tests, press ESC to exit the advanced tests.
10. Press F4 to save system and test information in the Support Ticket log file, HPSUPPT.TXT.
11.
Exit. Press F3 to exit and reboot.

12. 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 hardware summary and 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
Note
If Quiet Boot is enabled in BIOS Setup, 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
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.
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. Not all POST messages indicate a hardware,
software, or firmware failure—some messages are informational messages.
If the BIOS detects a terminal error condition, it halts POST after issuing a terminal error beep code—
up to four groups of 1 to 4 short beeps. The beep code indicates the POST routine in which the
terminal error occurred. The BIOS also issues a beep code (one long tone followed by two short
tones) during POST if the video configuration fails (no card installed or faulty) or if an external ROM
module does not properly checksum to zero.

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, and may be able to tell how well they are working or 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
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, if it is not already running.
2. Click Start, Programs, HP DMI, Setup.
To install the DMI from floppy disks or from the Recovery CD:
1. For floppy disks, copy the DMI software from the \omnibook\drivers\os_version\dmi directory of
either the hard disk or Recovery CD to two or more floppy disks (for example, copy the contents
of the \disk1 subdirectory to disk #1).
2. Start Windows, 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\os_version\dmi\disk1 directory on the CD.
Uninstalling the DMI Package
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.
HP OmniBook 2100/3000/3100Troubleshooting and Diagnostics3-21
Hewlett-Packard has developed a number of extensions to DMI to allow the enhanced features of HP
OmniBook computer to be managed with DMI, including features such as passwords and tattooing
(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.

BIOS Setup Utility
The BIOS Setup utility provides access to basic configuration settings. It is independent of the
operating system.
Running the BIOS Setup Utility
1. Close all applications, then shut down Windows and reboot the OmniBook. If necessary, you can
press CTRL+ALT+DEL to reboot.
2. During reboot, press F2 to start the BIOS Setup utility.
3. The pointing device or mouse is not active in the BIOS Setup utility. Press the RIGHT and LEFT
arrow keys to move among menus. Press the DOWN and UP arrow keys to move among
parameters in a menu. Press ENTER to change a setting. See the table below for more
information.
4. After you select the options you want, press F10 or use the Exit menu to exit the BIOS Setup
utility.
If the settings cause a conflict between devices during reboot, the system prompts you to run
BIOS Setup, and the conflicting settings are marked.

HP OmniBook 2100/3000/3100Replaceable Parts4-11
Reference Information
This chapter includes the following reference information:
• Password removal policy.
• Display quality statement.
• Service notes and obsolete repair parts.
Password Removal Policy
If the user forgets the system password, the user calls Technical Support to determine the proper
removal procedure. For the OmniBook 3000, 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.
5
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.
HP OmniBook 2100/3000/3100Reference Information5-1
Hewlett-Packard 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 workaround 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.
Service notes containing important repair information are issued periodically for the HP OmniBook
2100/3000/3100. These notes are available online at the Reseller website—see page vi. The following
table lists recent service notes. Much information from these notes is included in this edition of the
service manual.
