For Windows NT, Card Executive provides support for PC Cards, and Advanced Power
Management provides power management. If a PC Card icon and a Power icon are
displayed in the taskbar, these utilities are already installed. If these icons are not
present, see “To install Card Executive for Windows NT 4.0” on page 57 and “To install
APM for Windows NT 4.0” on page 43. You should install Card Executive before you
install networking support.
For Windows NT, the NT administrator password is initially blank. For system security,
you should change the NT administrator password in the Windows NT User Manager.
For Windows NT, the keyboard locale is initially set to match the Windows NT
language. For example, French Windows NT uses a French keyboard. If your
OmniBook has a different keyboard, such as French-Canadian, you should use
Keyboard Control Panel to change the locale and layout under Input Locales.

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.

The default pointing device driver (PS/2 TrackPoint) supports the enhanced features of
the pointing stick and the basic features of the touch pad.
You can customize the OmniBook to support enhanced touch pad features (see the next
topic). 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.
To customize the operation of the touch pad or pointing stick, see the section “Using the
OmniBook Pointing Devices” in the online Reference Guide.
Under Windows 2000, enhanced features for the pointing stick and touch pad are not
available at this time. Check the Customer Care website
(http://www.hp.com/cposupport/eschome.html) for PS/2 TrackPoint and touch pad
device drivers for Windows 2000. The default pointing device driver is the standard
PS/2 Compatible Mouse driver. To disable either pointing device, see “To run the BIOS
Setup utility” on page 62.

Using the OmniBook Display
To extend the life of the display
Observe the following guidelines to maximize the life of the backlight in the OmniBook
display.
• Set the brightness to the lowest comfortable setting (Fn+F1). If you are using an
external keyboard, Fn = left CTRL + left ALT.
• When working at your desk, connect an external monitor and turn off the internal
display (Fn+F5).

Thank you for selecting HP computing equipment. To optimize your comfort and
productivity, it is important that you set up your work area correctly and use your HP
equipment properly. With that in mind, we have developed some set-up and use
recommendations for you to follow based on established ergonomic principles.
Improper and prolonged use of keyboards and input devices are among those tasks that
have been associated with repetitive strain injury (RSI) to soft tissues in the hands and
arms. If you experience discomfort or pain while using any computing equipment,
discontinue use immediately and consult your physician as soon as possible.
In addition to the information on RSI given in this chapter, you may also consult the
online version of Working in Comfort preloaded on the hard disk of the your HP
OmniBook, or visit HP’s Working in Comfort website.
About Repetitive Strain Injury
Because your comfort and safety are our primary concern, we strongly recommend that
you use HP computing equipment in accordance with established ergonomic principles
and recommendations.
Scientific literature suggests that there may be a relationship between injury to soft
tissues—especially in the hands and arms—and prolonged, improper use of keyboards or
other equipment requiring repeated motions of the hands and forearms.
This literature also suggests that there are many other risk factors that may increase the
chance of such injury, commonly called Repetitive Strain Injury.
What is RSI?
Repetitive Strain Injury (RSI—also known as cumulative trauma disorder or repetitive
motion injury) is a type of injury where soft tissues in the body, such as muscles, nerves,
or tendons, become irritated or inflamed.

RSI has been a reported problem for those who perform repetitive tasks such as assembly
line work, meatpacking, sewing, playing musical instruments, and computer work.
RSI also has been observed in those who frequently engage in activities such as
carpentry, knitting, housework, gardening, tennis, windsurfing and lifting children.
What causes RSI?
The specific causes of RSI have not been established. Nevertheless, the incidence of RSI
has been associated with a variety of risk factors, including:
• Too many uninterrupted repetitions of an activity or motion.
• Performing an activity in an awkward or unnatural posture.
• Maintaining static posture for prolonged periods.
• Failing to take frequent short breaks.
• Other environmental and psychosocial factors.
In addition, there have been reports associating the occurrence of RSI with the use of
computer keyboards, mice, and other input devices. Also, certain medical conditions,
such as rheumatoid arthritis, obesity and diabetes, may predispose some people to this
type of injury.
What can I do to avoid RSI?
Some people who use computers may experience physical discomfort during their use.
This discomfort may be a symptom of a repetitive strain injury.
Properly setting up and using computing equipment can help to minimize your chances of
experiencing this discomfort. Well-designed and properly adjusted equipment alone may
not be sufficient to eliminate all potential problems.
Maintaining good posture and positioning when working on computers also has a
significant bearing on your comfort.
What if I experience discomfort?
If you are experiencing any discomfort, seek professional medical advice immediately.
Typically, the earlier a problem is diagnosed and treated, the easier it is to resolve.

Preparing Your Work Environment
When using HP computing equipment, it is important that your work environment
contribute to your comfort and productivity.
Your Chair
It’s very important that your chair provides a comfortable sitting position and offers the
following features:
• A stable base, such as five legs with casters. Make sure the casters are designed for
the type of floor you have in your workspace, whether it is bare or carpeted.
• A height- and tilt-adjustment feature. It should be easy to adjust your chair height
from 40 cm to 52 cm (15.5 inches to 20.5 inches) as measured from the top of the seat
pan to the floor. If you are much taller or shorter than average, you may need a chair
that can be adjusted beyond this range. Adjust your chair so that the work surface or
keyboard tray is at elbow height and your feet are flat on the floor with your knees
slightly bent below your hips. Ideally, the seat pan should be able to tilt both forward
(minimum of 5 degrees) and backward (minimum of 10 degrees). If the chair has an
adjustable seat pan, inclining the seat slightly forward will transfer some of the
pressure from the spine to the thighs and feet. This will relieve pressure on your back.

• A curved seat edge. The front of the seat should be curved and finished in a
“waterfall” edge.
• An adjustable back support in both height and forward and backward tilt. It is
important that the backrest correctly supports the lower part, or lumbar curve, of the
back.
• A freely rotating swivel so you can move easily from side-to-side.
• Fully adjustable and padded armrests. The chair arms should not interfere with
adjusting the chair or moving it close to your work surface.
Your Work Surface
Ideally, you should be able to adjust the height of your work surface.
A simple way to ensure your work surface is at the correct height is to first adjust the
height of the seat-pan of your chair. With your chair properly adjusted and your feet
firmly on the floor, adjust the work surface height until your forearms are parallel to the
floor when you have your fingers on the keyboard or other input device.
Your Work Posture
Sitting in one position for long periods can be uncomfortable. To minimize the potential
for physical discomfort or injury, it’s important that you maintain proper posture.
• Back: While sitting at your work surface, make sure your back is supported by the
chair’s backrest in an erect position or angled slightly backwards.
• Arms: Your arms should be relaxed and loose, elbows close to your sides, with
forearms and hands approximately parallel to the floor.
