Hardware Reference Guide 1–5

A Look at the Computer

Using the Scroll Mouse

The mouse directs the cursor on the Windows desktop. Use the mouse
to move quickly and easily through a document or Web site.

Moving the scroll wheel on your mouse through a document or Web
site is faster than using the scroll bar. You can use the scroll wheel to:

■ Scroll forward or backward through a document or Web site by

turning the scroll wheel forward or backward.

■ Autoscroll by pressing down on the scroll wheel until it clicks

(you will see an autoscroll icon on your desktop). Move the
mouse vertically, horizontally, or diagonally to scroll in the
desired direction. The farther you move the cursor from the
starting point icon, the faster the scrolling occurs. To stop, press
the mouse button.

✎

Some mouse functions, such as autoscrolling, may not work with all
software.

Refer to the Learning More About Your Computer guide contained on
the Documentation Library CD for information on customizing your
mouse.

Using the Wireless Wheel Mouse

The wireless wheel mouse is available with select models. It has the
same features and functions as the scroll mouse with the addition of a
connect receiver box. Refer to the Getting Started guide included with
your computer for instructions on installing the batteries.

When using the wireless mouse:

■ Replace the batteries approximately every six months. The

wireless mouse does not alert you when the batteries are low.

■ For optimal performance, place the connect receiver box at least

8-inches/20-centimeters away from other electrical devices, such
as the computer, monitor or external storage equipment.

■ Refer to the “Solving Minor Problems” section in your

1–6 Hardware Reference Guide

Getting Started Guide if your wireless mouse does not function
properly.

Using the USB Optical Mouse

The USB optical mouse is available with select models. It provides
the same functions as the scroll mouse and wireless wheel mouse
except it uses an optical sensor instead of a mechanical ball to
determine the position of the cursor on the screen. The surface on
which you use the optical mouse plays an important role in tracking
the cursor. When using the optical mouse:

■ Use a mousepad or a white sheet of paper underneath your

mouse. Using it on a glass or see-through surface will inhibit the
ability of the sensor to track the cursor.

■ Avoid using the mouse on a reflective surface such as a mirror or

shiny metal desk. This may cause tracking problems.

■ Some wood grains and grooved surfaces may also cause tracking

problems.

■ Refer to the “Solving Minor Problems” section in your

Getting Started Guide if your optical mouse does not function
properly.

There are several different types of memory modules. Install the same
type of memory currently in your computer. To find your type of
memory, go to the compaq.com/athome/memory Web site.

No tools are needed to remove, replace, or upgrade memory modules.

Electrostatic Discharge

A discharge of static electricity from a finger or other electrostatic
conductor may damage electronic components. Before handling
electrostatic-sensitive components, discharge static electricity by one
the methods described in this appendix.

Preventing Electrostatic Damage

When Handling Drives

■ Before handling a drive, discharge static electricity by touching

the unpainted metal surface or lug nuts on the connectors on the
rear of the computer.

■ Avoid touching connector pins on the computer or a drive.

A

When Installing Internal Components

■ Keep components in their electrostatic-safe containers until you

are ready to install them.

■ Have everything needed for the installation within reach so that

you do not have to leave the area after beginning installation.

■ Use nonmagnetic tools.

■ Avoid touching pins, leads, and circuitry. Handle electronic

components as little as possible.

■ If you remove a component, place it in an electrostatic-safe

container.
