HP OmniBook 4100 User’s Handbook
• Using This Online Handbook.
• Finding More Information.
• Notice.
This handbook describes how to use the OmniBook with a Microsoft® Windows®
operating system. It focuses on the special Hewlett-Packard hardware and software,
not the Windows operating system itself. For questions about the use of the
operating system, refer to the Microsoft Windows manual shipped with the
OmniBook.
Using This Online Handbook
This online User’s Handbook looks similar to a printed manual—and it works like a
printed manual in many ways, too. However, you can do several handy things you
can’t do with a manual. For example, you can make the type larger or smaller. You
can click pictures to enlarge them. You can add electronic bookmarks for marking
key information. And you can print all or part of the manual on your printer.
• Press F1. You’ll see a description of the features of this online manual.
Finding More Information
This OmniBook User’s Handbook introduces the OmniBook and shows you how to
operate and troubleshoot your OmniBook. For more information about using your
OmniBook, look in these additional places:
• The printed OmniBook Reference Guide shows how to set up the operating
system, install and connect accessories, and maintain and upgrade the
OmniBook.
• The Microsoft Windows manual, shipped with your OmniBook, contains
information about using the standard features of your Windows operating
system.
• The online Help for Windows applications provides information about those
applications. Use the Help menu or Help button, or just press F1.
• The OmniBook Notes icon gives late-breaking information available after the
online manual was completed. Click Start, Programs, OmniBook Library,
OmniBook Notes.
• Many bookstores have books about Windows for people with different levels of
experience.
• For updates to the BIOS and other technical information, connect to our website
on the Internet at http://www.hp.com/omnibook.
• You can obtain a backup copy of the OmniBook Reference Guide (which came
with your OmniBook) from our website (http://www.hp.com/omnibook). You can
view or print it using an Acrobat viewer, available free of charge through our

5
website. To re-install the User’s Handbook onto your hard drive, insert the
Recovery CD and run Omnibook\Hputils\Disk1\Setup.Exe.
• OmniBook accessories may be purchased online. For the latest information, visit
our website at http://www.hp.com/omnibook.

1. Introducing the OmniBook
• Identifying the Parts of the OmniBook.
• Learning About Windows.
• Safety Information.
• Working in Comfort.
Keep in mind the following features as you learn about your OmniBook.
• The OmniBook’s modular design provides maximum expandability without
compromising portability.
• The high-performance Pentium® CPU with MMX™ technology and enhanced
IDE hard drive provide you with the processing power needed to handle complex
graphics and large sound files.
• Two PC Card slots give you the ability to use standard PC Cards, such as a LAN
adapter or memory cards.
• The floppy disk drive in the plug-in module bay can be replaced with a CD-ROM
drive, DVD drive, LS-120 drive, or second battery.
• You can use the floppy disk drive outside the module bay by connecting it to the
parallel port using the optional HP F1473A external floppy disk drive cable.
• Battery operating time can be doubled when you carry an additional primary
battery to be installed when the first runs down, or when you install a second
battery in the plug-in module bay.

Safety Information
AC Adapter Safety
• Use only the ac adapter shipped with the OmniBook (HP part number F1454A).
Using any other ac adapter could damage the OmniBook and may void your
warranty. Refer to the warranty statement for your product.
Battery Safety

9
• To avoid risk of fire, burns, or damage to your battery, do not allow a metal
object to touch across the battery contacts.
• Use only the battery designated for use with your model of the HP OmniBook.
• Do not disassemble. There are no serviceable parts inside.
• Do not dispose of the battery in fire or water.
• Handle a damaged or leaking battery with extreme care. If you come in contact
with the electrolyte, wash the exposed area with soap and water. If it contacts
the eye, flush the eye with water for 15 minutes and seek medical attention.
• Do not expose the battery to high storage temperatures—above 60 °C (140 °F).
• When discarding a battery, contact your local waste disposal provider regarding
local restrictions on the disposal or recycling of batteries.
• To obtain a replacement battery, contact your local dealer or HP sales office.
• The battery cannot charge if the ambient temperature exceeds 45 °C (113 °F).

following precautions are recommended:
• If the unit requires service, contact an authorized HP service center—see the
OmniBook Support and Service booklet.
• Do not attempt to make any adjustment of the unit.
• Avoid direct eye exposure to the infrared LED beam. Be aware that the beam is
invisible light and cannot be seen.
• Do not attempt to view the infrared LED beam with any type of optical device.
Laser Safety
The CD-ROM drive used with the OmniBook is certified as a Class 1 laser device
according to the U.S. Department of Health and Human Services (DHHS) Radiation
Performance Standard and International Standards IEC 825 / IEC 825-1 (EN60825 /
EN60825-1). This device is not considered harmful, but the following precautions are
recommended:
• Ensure proper use by reading and following the instructions carefully.
• If the unit requires service, contact an authorized HP service center—see the
OmniBook Support and Service booklet.
• Do not attempt to make any adjustment of the unit.
• Avoid direct exposure to the laser beam—do not open the unit.

Two pointing devices (pointing stick and touch pad) are built into your OmniBook.
The default pointing device driver supports the enhanced features of the pointing
stick and basic features of the touch pad.
You can customize the OmniBook to support enhanced touch pad features. If you do
this, keep in mind that you are selecting enhanced features for the touch pad only.
You cannot activate enhanced features for both simultaneously.
1. Pointing stick (pressure-sensitive pointing device).
2. Touch pad (touch-sensitive pointing device).
3. Click buttons (two above and two below the touch pad).
Both pointing devices use these click buttons, which work like the left and right
buttons on a standard mouse. What the buttons do depends on the software
being used.
To use the built-in pointing devices
1. Place your hands in the typing position.
2. Pointing stick. With your index finger, press the pointing device in the direction
you want the pointer to move. Pressing away from you moves the pointer up the
screen; pressing toward you moves the pointer down the screen.
Touch pad. Move a thumb or finger across the touch pad in the direction you
want the pointer to move.
3. Use the left and right click buttons, which function like the left and right buttons
on a mouse, to make your selection.
• To open an application, move the pointer over the icon, then press the left
button twice rapidly.
• To make menu selections, move the pointer to the item and press the left
button once.
• To open the shortcut menu for an item, move the pointer over the item and
click the right button.

14
• To drag an item, move the pointer over the item. Press and hold the left
button while you move the pointer to the new location. Release the button.
To activate full touch pad capabilities
The built-in pointing stick driver supports only basic touch pad features. To activate
