Your Aspire computer system is made up of several
components. These include the computer itself, the
monitor, keyboard, mouse and speakers. This section
provides a brief description of the main component
features.
The pointing device included in your Aspire computer
system is an optical mouse. Unlike a traditional mouse that
requires the use of a mouse pad for its ball system to work
effectively, an optical mouse can be used on almost any
surface. This allows you to operate your mouse anywhere in
the vicinity of your computer - an important advantage on
a cluttered desktop.
Your optical mouse works by continuously bouncing a small
beam of light off the surface on which it is being operated.
The information from the returning light beams is read by
the mouse and transmitted to the computer. In this way,
your computer is able to calculate the precise movements of
the mouse.
Although your mouse can be used effectively on most
surfaces, highly reflective materials, such as glass or metal,
can distort the light signal. If you wish to operate your
mouse on a reflective surface you should first cover the
surface with a non-reflective object, such as a book or a
sheet of paper.
Two types of optical mouse are available: a standard corded
mouse and a cordless mouse. The type of mouse included in
your system depends on the system model you purchased.
Your mouse features standard controls: two buttons and a
scroll wheel for convenient navigation in documents and
web pages.
