HP OmniBook XE2Removal and Replacement2-19
Installing a New Serial Number Label
If you do not have a master file that creates serial number labels, get a copy from the Reseller website
(see page vi) under Product Support Information in the Service and Support Library.
1. Using any PC connected to a laser printer, open the master serial label file, 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.
2. 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.
3. While holding the paper label in place, attach a serial label overlay (HP Part #7121-7525) into the
outer recess. It covers and protects the serial label.

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.
•
3-2Troubleshooting and DiagnosticsHP OmniBook XE2
•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 3-11).
•–and–
Function Tests. Run tests that check the repaired function, such as in the OmniBook diagnostic
•
program (page 3-11).
–and–
Failed Tests. Run any other tests that failed during troubleshooting.
If you can’t isolate the cause of a problem using the diagnostic tools, you can use the suggestions in
the following table to help find the problem.

Diagnostic Tools
This section describes the following diagnostic tools you can use for troubleshooting and repairing the
OmniBook:
•OmniBook hardware diagnostic program (below).
•Power-on self-test (page 3-16).
•Desktop Management Interface (page 3-20).
•BIOS Setup utility (page 3-22).
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 Floppy 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–
If TopTools is installed, use the DiagTools page to create the disk.
• On any computer with a CD-ROM drive, run
directory on the OmniBook Recovery CD.

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
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 the OmniBook Recovery CD or from floppy disks:
1.If you do not have a CD-ROM drive, create installation floppy disks
•On any computer with a CD-ROM drive, copy the DMI software from the dmi directory of
the Recovery CD (under \omnibook\drivers) to two or more floppy disks (for example, copy
the contents of the \disk1 subdirectory to disk #1).
• On any computer with World Wide Web access, download the Top Tools package from the
OmniBook website (see page vi), then create the floppy disks as directed.
2.Start Windows, if it is not already running.
3.Insert the Recovery CD into the CD-ROM drive, or insert disk #1 into the floppy drive.
4.Select and run the SETUP program from the dmi\disk1 directory on the CD (under
\omnibook\drivers), or from floppy disk #1.
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
3-20Troubleshooting and DiagnosticsHP OmniBook XE2
manufacturers, including Hewlett-Packard, to define a standard method of managing the physical and
logical components of personal computers.
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.

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.

This chapter includes the following reference information:
•Password removal policy.
•Display quality statement.
•Technology Codes.
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 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.

OmniBook XE Technology Codes
HP does not change the product name every time the product technology changes. While this
helps ensure continuing market momentum for the products, it complicates the technology
deployment and support processes.
To help with these processes, HP has chosen to add a technology code (sometimes also
referred to as sub-branding") to the serial number label. The chart below, shows the
technology codes and the changes they signify for the Products based on the Omnibook XE2
technology.
Since the BIOS needs to be matched to the hardware in the system, the team has chosen to
use the same code to indicate the BIOS technology and the hardware technology.
Note that systems produced before the Omnibook XE2-DD technology will NOT have this
code printed on the serial number label, but the first two characters of the BIOS ID (e.g.
DB.M1.04) still gives an indication of the hardware technology.
