WARNING

Improper use of keyboards and other input devices has been associated with ergonomic injury. For more information about reducing your risk, visit our ergonomics website at www.hp.com/ergo.

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.

Reference Guide 35

Operating the OmniBook

Working in Comfort

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.

36 Reference Guide

Operating the OmniBook

Working in Comfort

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.

Reference Guide 37

Operating the OmniBook

Working in Comfort

• 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.

38 Reference Guide

Operating the OmniBook

Working in Comfort

• Wrists: Your wrists should be as straight as possible while using the keyboard,

mouse or trackball. They should not be bent sideways, or more than 10 degrees up or down.

• Legs: Your thighs should be horizontal or angled slightly downward. Your lower legs

should be near a right angle to your thighs. Your feet should rest flat on the floor. If necessary, use a footrest, but double check that you have your seat height adjusted correctly before getting a footrest.

• Head: Your head should be upright or tilted slightly forward. Avoid working with

your head or trunk twisted.

• Overall: Change your position frequently and take regular breaks to avoid fatigue.

Setting Up Your HP Computing Equipment

Make sure that all the elements of your HP computer system—monitor, document holder, keyboard, mice and other input devices, and headphones and speakers—are optimally arranged and adjusted to meet your personal requirements. The recommendations that follow will help you achieve this.

Your HP Monitor

It is important that your monitor screen be clean and positioned correctly to improve readability and help you work comfortably. Glare, high contrast, reflections, dirt and dust will interfere with what you see on the screen. The recommendations that follow can help you achieve a comfortable arrangement.

Reference Guide 39

Operating the OmniBook

Working in Comfort

• The top of your monitor screen should be at or slightly below eye level. Most HP

monitors come with a tilt-and-swivel feature that makes it easy to adjust the screen position.

• To avoid obscuring your view, the screen should be positioned perpendicular to your

line of sight; that is, straight on.

• To avoid glare or reflection, try to position the monitor so the screen is at a right angle

to your window rather than in front of it. If reflection or glare persists, tilting the screen forward may help.

• Maintain a comfortable viewing distance to the screen. Most people prefer a viewing

distance of approximately 46 to 76 cm (18 to 30 inches), depending on monitor size. Character size and the amount of space available on the work surface can affect this distance.

• Text should be easy to read. To help ease eyestrain, adjust text attributes such as

character size, spacing, and color. In addition, you will need to use the controls provided with your monitor to adjust the visual settings so that contrast and brightness levels are comfortable for you. High contrast and low brightness is usually the preferable combination.

• The monitor should be free from flicker. If the image on your screen is not stable, the

monitor may require repair or adjustment.

• When possible, use a program that has a simple user interface, such as easily

identifiable icons and pull-down menus. Also, screen information should be displayed in a structured and well-organized way.

40 Reference Guide

Operating the OmniBook

Working in Comfort

Monitor Use Specifications

• When viewing your monitor, your head should not be tilted more than 15 degrees

forward.

• You should not have to look up more than 5 degrees above horizontal or down more

than 30 degrees below horizontal for normal work tasks, such as typing or reading.

Document Holders

When keying in data from a hard-copy document, placing it in a document holder rather than on a flat surface will make it easier to read. The following recommendations should be observed when using a document holder:

• The document holder should be at approximately the same height and distance from

your eyes as the screen, and as close to the monitor as possible to prevent neck twisting. Some users prefer a document holder mounted to the monitor while others prefer the document holder positioned between the screen and keyboard.

• If the primary task is to view documents rather than using the monitor, the document

holder may be placed directly in front of the keyboard with the monitor slightly to the side.

• To help reduce stress on your neck and prevent eye fatigue, try to minimize the

movement of your head and eyes while using a document holder.

Your HP Keyboard

The proper positioning and use of your HP keyboard is important when using HP computing equipment. Be sure to observe the following recommendations to optimize your comfort and safety:

Reference Guide 41

Operating the OmniBook

Working in Comfort

• We recommend you place your keyboard in front of the screen or document holder,

whichever is viewed the most. Your HP keyboard has long cables so you can place it in the position that is most comfortable for you while you are using your system.

• Because HP keyboards vary in depth, you’ll want to be sure that your work surface or

keyboard tray has sufficient room to accommodate your model. The keyboard tray should be wide enough to hold both the keyboard and mouse or trackball: 66 to 71 cm (26 to 28 inches).

• Your HP keyboard may have a kickstand that can be opened or closed to raise or

lower the keyboard angle. If you are in the correct sitting position with your elbows at about the same level as the work surface, you may not need to use it. However, if your elbows are below the work surface, you may wish to use the kickstand to raise the back of the keyboard.

• An adjustable keyboard tray may be useful if you cannot adjust your chair or work

surface to the proper height for typing. It should adjust in height from 64 to 76 cm (25 to 30 inches) above the floor and tilt forward and backward to help you find the most comfortable position. Note that research has shown that there may be less muscle tension in shoulders and forearms with the keyboard tilted away from you.

• When using your HP keyboard, remember it takes very little pressure or force from

your fingers to activate the keys. Improper typing style—the use of too much force— can place unnecessary stress on the tendons and muscles in your hands, wrists, and forearms.

• Make sure that your hands are in a neutral position when you use your keyboard. This

means that your forearms, wrists, and hands should be in a straight line.

• The keyboard has a low profile to help prevent excessive bending of your wrists while

typing. Literature suggests that you should not bend your wrists sideways or more than 10 degrees up or down. Keep your wrists straight by moving your entire hand and forearm over to use the function keys or numeric keypad.

• You may use a palm rest to help keep your hands and wrists in a comfortable and

neutral position when you are not typing. Some HP keyboards come with an integrated palm rest. If you use a palm rest, see that it is rounded and padded, and flush in height with the front edge of the keyboard. Note that your palms—not your wrists—should rest on the palm rest. If you don’t have a palm rest, try not to rest your wrists on a sharp edge, such as a work surface edge.

Mice and Other Input Devices

Various aspects of using mice and other input devices may increase your risk of discomfort or injury. If you connect an external mouse to your OmniBook, observing the following recommendations may reduce that risk.

42 Reference Guide

Operating the OmniBook

Working in Comfort

• As with the keyboard, try to keep your hand, wrist, and forearm in a neutral position

while using your mouse or other input device.

• When using a stylus or light pen with a graphics tablet, don’t grip the stylus tightly.

Keep your hand and fingers relaxed and try to maintain a neutral posture in your hand, wrist and forearm.

• If you use your thumb to rotate the ball on a trackball or spaceball, keep it in a

relaxed, natural shape, and maintain a neutral posture in your hand, wrist, and forearm.

• Hold the mouse gently by draping your fingers over it. Keep your hand relaxed and

fingers loose. Do not grip the mouse tightly.

• It takes very little pressure or force from your fingers to activate the buttons or scroll

wheel on your mouse, scrolling mouse, trackball, or other input device. Using too much force can place unnecessary stress on the tendons and muscles in your hands, wrists, and forearms.

• If you are using a scrolling mouse, be sure to keep your fingers and hand in a relaxed,

neutral position when activating the scroll wheel. Also, this type of mouse features software that can minimize the number of mouse movements or button clicks.

• When using a mouse, trackball, stylus and graphics tablet, or other input device,

position it as close to the keyboard as possible, and keep it at the same level so you do not have to stretch while using it.

• Use a good quality mouse pad to enable the mouse to work most effectively and

reduce unnecessary hand and wrist movements.

• Be sure to keep your mouse and trackball clean. Regular removal of accumulated dust

and dirt helps ensure proper tracking and reduces unnecessary hand and wrist motions.

Reference Guide 43

Operating the OmniBook

Working in Comfort

Headphones and Speakers

Listening to loud sounds for prolonged periods may permanently damage your hearing. To avoid discomfort from unexpected noise, always turn down the volume before connecting headphones or speakers to your HP equipment.

When you put on the headphones, slowly increase the volume until you find a comfortable listening level, then leave the volume control in that position.

Comfort and Safety Checklist

These recommendations are drawn from the latest available international ergonomic standards and recommendations, including ISO 9241 and ANSI/HFS 100-1988.

General

• Work Surface Height: Adjust either your seat height, work surface, or both, to

position the work surface at approximately elbow height.

• Work Surface Arrangement: Make sure frequently used equipment is within easy

reach. For example, if you are primarily using the keyboard, place it directly in front of you, not to the side. If you are primarily using the mouse, place it in front of your hand or arm. If you are using both a mouse and keyboard, place them both at the same work surface height and close together. If a palm rest is used, the height should be flush with the front edge of the keyboard. Other items, such as your telephone or notepad, also should be considered.

• Monitor: Place your monitor so that the top of the screen is at, or slightly below, eye

level (up to 15 degrees).

44 Reference Guide

Operating the OmniBook

Working in Comfort

• Head: Do not tilt your head forward by more than 15 degrees, and try not to turn your

head toward the side.

• 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: Make sure your arms and elbows are relaxed and loose, with your upper arm

perpendicular to the floor or slightly forward. Keep your forearms and hands approximately parallel with the floor with elbows bent between 70 and 115 degrees. Keep your elbows close to your sides (less than 20 degrees away from your body).

• Legs: Your thighs should be horizontal or angled slightly downward. Your lower legs

should be near a right angle to your thighs. Make sure there is sufficient room under the work surface for your legs.

• Feet: If after adjusting your chair you cannot rest your feet comfortably on the floor,

use a footrest, preferably one that can be adjusted in height and angle.

Overall

• Look away from the screen from time-to-time to help reduce eyestrain. Focus on

distant objects briefly, and blink periodically to lubricate your eyes. You also should have your eyes checked on a regular basis and ensure your eyeglass prescription is suitable for working on a monitor screen.

• Remember to occasionally shift position and move your body. Keeping your body in

one position for long periods is unnatural and stressful. When prolonged work is required, take frequent short breaks. As a rule of thumb, a five- or ten-minute break every hour is a good idea. Short, frequent breaks are more beneficial than longer less frequent breaks. Data show that people who work for long periods of time without a break may be more prone to injury.

• Changing tasks frequently will help prevent muscle stiffness. Examples: alternating

between keyboarding, reading, writing, filing, and moving around in your work environment, helps you maintain a relaxed posture. Occasionally stretch the muscles in your hands, arms, shoulders, neck, and back. You should stretch at least as often as you take brief task breaks—at least once every hour.

• Discomfort may be alleviated by using alternative ergonomic designs and accessories

such as ergonomically personalized chairs, palm rests, keyboard trays, alternative input devices, prescription eyeglasses, anti-glare screens, and more. Seek additional information from the sources available to you, including your employer, doctor, local office supply store, and the information sources listed in the online version of Working in Comfort, which is preloaded on the hard disk of your HP computing equipment.

Reference Guide 45

Working in Comfort

Your HP OmniBook Computer

You can use your HP OmniBook computer virtually anywhere, anytime. The following recommendations should help you work more comfortably.

Note that if you are using your portable computer as your primary computer, or using it for extended periods, you should use it with a full-size keyboard, monitor and mouse. This will give your portable computer the adjustability and comfort features of a desktop unit. HP port replicators offer quick, easy connections to these devices. More information on how to prepare your workspace environment and set up your HP equipment is available in other sections of Working in Comfort, which is preloaded on the hard disk of your HP computing equipment.

Preparing Your Mobile Work Environment

• Use a chair that provides good support for your lower back. If an adjustable chair is

not available, you can use a pillow or rolled-up towel to provide lower back support.

• Try to keep your thighs parallel to the floor and your feet flat on the floor. In a mobile

environment, you can do this by using a phone book or briefcase to support your feet.

• Adjust the height of either your work surface or chair to keep your arms in a neutral

position. Your arms should be relaxed and loose, elbows at your sides, with the forearms and hands parallel with the floor.

• Position your notebook computer display to minimize glare and reflection. For

example, on an airplane, lower the window shade, or in a hotel room, draw the curtains. You also should maintain a comfortable viewing distance, approximately 40 to 60 cm (16 to 24 inches). Adjust the angle of your display to help keep your head angled slightly downward in a comfortable position.

Using Your Mobile Computer

• Position the computer so your wrists and hands are in a neutral position. Your wrists

should be as straight as possible and should not have to bend sideways or more than 10 degrees up or down. If your notebook computer does not have a built-in palm rest, you can use a rolled-up towel.

• Try to type as lightly as possible. The notebook keyboard requires little force to

activate.

Managing Battery Power

Reference Guide 49

Managing Battery Power

How Power is Managed

The OmniBook conserves power by using software that controls battery charging and power drain.

If you’re using Windows 95 or Windows 98, Advanced Power Management (APM) is preinstalled on the OmniBook.

If you’re using Windows NT 4.0, look for a Power icon in the taskbar. If the icon is

present, APM is installed. If not, see “To install APM for Windows NT 4.0” on page 51.

If you’re using Windows 2000, power management is built into Windows.

The OmniBook provides several safeguards so you won’t be surprised by a dead-battery condition, including the following:

• The status lights on the battery show the remaining battery charge.

• Built-in warnings are displayed for low-battery conditions.

• The OmniBook automatically turns off when the battery charge gets too low—your

session continues when you start recharging the battery or insert a fresh battery.

Data on any of the drives is not affected by a low battery—unless the battery runs down completely while writing data to the drive, or if the battery in a PC RAM card is also low.

50 Reference Guide

Monitoring Battery Power

The primary source of power for the OmniBook is its rechargeable battery pack. You can

use the ac adapter to recharge the battery—or to run on ac power to preserve the battery.

Managing Battery Power

Monitoring Battery Power

Important

Running external connections is a power-intensive operation that significantly shortens the length of a battery session. Whenever possible, connect the ac adapter when using external connections.

In addition to the replaceable battery, there is a permanent, internal backup battery, which recharges whenever the OmniBook is on or connected to ac. It maintains certain internal settings, such as the clock.

To install APM for Windows NT 4.0

If a Power icon (battery or power plug) is present in the taskbar, APM is installed. If the icon is not present, you can install APM using the steps below.

The Advanced Power Management (APM) driver for Windows NT 4.0 is located on the OmniBook’s hard disk drive. You set up APM from the Windows Start menu. (The APM driver is also located on the Recovery CD in \OmniBook\Drivers\NT4 or Apm.)

Phoenix APM adds the following capabilities to the OmniBook:

• Improved battery life under Windows NT 4.0.

• PC Card power management.

• Convenient user control and monitoring of power settings and status.

1. To install APM, click Start, Programs, OmniBook, Phoenix Advanced Power

The OmniBook’s plug-in module bay accepts a second battery. See “Using Plug-In Modules” on page 62 for information about installing plug-in modules.

Reference Guide 55

Managing Battery Power

Conserving Battery Power

The OmniBook uses to conserve battery power. You can manage this software to

optimize your battery operating time. If you’re using Windows 95 or Windows 98, Advanced Power Management (APM) is preinstalled on the OmniBook. If you’re using Windows NT 4.0, make sure APM is installed (see “To install APM for Windows NT

4.0” on page 51). If you’re using Windows 2000, power management is built into Windows.

To save battery power

Follow these suggestions to conserve battery power.

• Plug in the ac adapter, especially while using the floppy disk drive, the CD-ROM

drive, or any external connections.

• Put the OmniBook in Suspend mode whenever you are not using it for a short while:

press the blue power button for approximately 1 second or click Start, Suspend (Windows 95) or Start, Shut Down, Standby (Windows 98 and 2000).

• Put the OmniBook in Hibernate mode whenever you want to save your current

session, but will not be using the computer for several hours or more (Fn+F12).

• Shut down the OmniBook whenever you will not be using it for several hours or

more. Click Start, Shut Down. The current session is not saved.

• Press Fn+F1 to turn the brightness of the display down to the lowest comfortable

level. This reduces the backlight power and extends the life of your OmniBook display.

• Set the automatic time-out settings to emphasize saving power (see “To set power

time-outs” on page 57). For a model with a dual-speed processor, use the lower speed on battery power (see “To control the processor speed” on page 58). The default settings conserve battery power.

• If you work with an application that uses the serial port or a PC Card, exit the

application when you are done using it.

• If you have an I/O PC Card—that is, a PC Card having an external connection, such

as a modem or network card—remove it when you are not using it. Some I/O cards use significant power, even while they’re inactive.

Managing Battery Power

Conserving Battery Power

To control the processor speed

If your OmniBook contains a high-speed Pentium III processor with Intel SpeedStep Technology, you can change settings that control the processor speed. If the taskbar contains an Intel SpeedStep Technology icon, your computer has this feature.

With the default settings, the processor speed changes automatically according to the power source (ac adapter or battery). The lower speed uses power more efficiently and is normally used when the computer is running on battery power.

Automatic Speed Changes

• If you reboot the computer with the ac adapter plugged in, the processor starts at high

speed. If the computer is on battery power, the processor starts at low speed.

• If you unplug the ac adapter while the computer is running or suspended, the

processor changes to low speed.

• If you plug in the ac adapter while the computer is running or suspended, the

processor changes to high speed.

Changing Speed Settings

• To set the speed used by the processor at boot, or to disable the dual-speed feature,

change the Intel SpeedStep Technology setting in BIOS Setup in the Power menu— see “Power Menu” on page 90.

• To set the speed used by the processor while Windows is running, double-click the

Intel SpeedStep Technology icon in the taskbar or use the Control Panel Power icon.

58 Reference Guide

Managing Battery Power

Conserving Battery Power

To get the most from your battery

The following are some further suggestions for the best management of your OmniBook batteries.

• Do not leave batteries unused for long periods of time. If you have more than one,

rotate them.

• If you normally use ac power, make a practice of at least once a week using the

battery as your power source.

• Unplug the ac adapter when the computer is not in use.

• To preserve the life of your battery, be sure to charge the battery regularly.

• For long-term storage, the battery must be charged at 20-50% to save capacity loss by

self-discharge and to avoid deterioration of battery performance. Storage in a 100% charged condition can cause higher self-discharge and deterioration of discharge

capacity—even after recharging—compared to storage in a 20-50% charged condition.

• For a temporary change, press Fn+F5 to cycle through the display options (Internal,

External, Both).

• For a permanent change in which display is active, change the Video Display Device

setting in the BIOS Setup utility (see below).

• For a display connected to a video adapter in a docking system, the docking display is

automatically selected when it is detected. To change this behavior, change the Primary Video Adapter setting in the BIOS Setup utility (see below).

To change BIOS display settings, see the next topic.

To change display settings in the BIOS Setup utility

1. From the Start menu, shut down, then restart the OmniBook.

2. When you see the HP logo, press F2 to enter the BIOS Setup utility.

3. From the Main menu, use the down arrow to highlight Video Display Device.

4. Press ENTER to view choices.

6. Similarly, highlight Primary Video Adapter. Select Auto (to automatically switch to

an external video adapter in a docking system) or Internal (to reserve the external display for special use, such as multiple displays in Windows 98).

7. Press F10 to save settings and exit Setup.

To use an external monitor

• If you attach an external monitor to the OmniBook, you can press Fn+F5 to switch

between the internal OmniBook display and the external monitor. The internal display

supports settings up to 1024 × 768 resolution and 16M colors (24- or 32-bit). You can change display settings using Control Panel Display or right-clicking the desktop and clicking Properties.

• If you need to use both displays at the same time, you can press Fn+F5 again to show

the same image on both displays. However, by default, the image is limited by the internal display to 1024 × 768 pixels, so at a higher resolution you see only part of the desktop on both displays. This doesn’t happen if you use only the external monitor. If you need to increase the refresh rate on the external monitor, you can switch to only the external monitor or you can make the internal or external display a “secondary” display—you make this setting on the Display tab (in Windows 98 or 2000, you have to click Advanced on the Settings tab first).

• In Windows 98, you can enable the Extended Desktop (dual displays), which spreads

the desktop across two displays. To do this, right-click display 2 on the Settings tab and select Enable. You can set different resolutions and numbers of colors for each display. However, using the Extended Desktop requires video memory to be shared. For this reason, higher resolutions and higher numbers of colors may cause unexpected behavior on the displays. We recommend starting with 1024 × 768 resolution on the external display and 64K colors (16-bit) on both displays. You can try higher settings to see whether they work for your applications. In addition, certain operations such as playing DVDs and running 3D graphics require extra video memory, so you may have to use lower display settings.

See OmniBook Notes in the online OmniBook Library for any last-minute information about display operation.

Before installing the memory module, discharge your body’s static electricity by touching the metal shielding around the connectors on the rear of the OmniBook.

For a model with “4150 B” after the serial number, you must use only PC-100 type RAM modules—other RAM modules will not function.

1. From the Start menu, shut down the OmniBook.

2. Important. Unplug the ac adapter, if present, and remove the battery. (Remove a

second battery if one is installed.)

3. Turn the unit bottom side up, then remove the two screws from the RAM cover and

Configuring the OmniBook

Using BIOS Setup

The BIOS (Basic Input and Output System) Setup utility is a menu-driven utility that enables you to make changes to the system configuration and tailor the operation of your OmniBook to your individual work needs.

The settings made in the BIOS Setup utility generally control the hardware and consequently have a fundamental effect on how the OmniBook operates.

This section describes the BIOS Setup utility menus and options in detail.

To run the BIOS Setup utility

1. Close all applications, then shut down Windows and restart the OmniBook.

2. When you see the HP logo, press F2 to enter the BIOS Setup utility.

3. The pointing devices are 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 F5 or F6 to move through values for the current parameter or press ENTER to change a setting. See the tables 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.

5. If the settings cause a conflict between devices during reboot, the system prompts you

to run BIOS Setup, and the conflicting settings are marked.

The following tables describe BIOS settings for BIOS version 3.05. If your BIOS is a different version, some settings may differ from those shown.
