Computing tips
❖Save your work frequently.
Your work stays in the computer’s temporary memory until you save it
to the disk. You will lose all unsaved work, if, for example, a system
error occurs and you must restart your computer, or your battery runs
out of charge while you are working. Your computer can be
configured to warn you when the battery is running low.
HINT: Some programs have an automatic save feature that you can turn on.
This feature saves your file to the hard disk at preset intervals. See your
software documentation for details.
❖Back up your files to diskettes (or other removable storage media) on
a regular basis. Label the backup copies clearly and store them in a
safe place.

16 Playing a CD or DVD
RG 5.375 x 8.375 ver 2.3.4
❖Scan all new files for viruses.
❖Never turn off the computer if a drive indicator light indicates a drive
is active.
The Windows® XP operating system records information, such as your
desktop setup, during its shutdown procedure. If you do not let the operating
system shut down normally, details such as new icon positions may be lost.
Using the TouchPadTM
The TouchPad, the touch-sensitive cutout in front of the keyboard, enables
you to move the cursor by brushing your finger on the surface in the
direction you want the cursor to move. To move the cursor to the top of the
screen, move your finger on the TouchPad away from you. To move the
cursor to the bottom, do the opposite.
For more information on the TouchPad, see the electronic user’s guide.
Primary and secondary control buttons
When you want to click or choose an item, use the TouchPad to move the
pointer/cursor to the item. Once the pointer/cursor is positioned, you can
click it into place by either double-tapping the TouchPad or clicking the
control buttons.
The control buttons are adjacent to the TouchPad and are used like the
buttons on a mouse. The primary control button is the left one and
corresponds to the left mouse button. To double-click, press the primary
button twice in rapid succession.
The function of the secondary button depends on the program you are
using. It usually corresponds to the right mouse button. Check your
program’s documentation to find whether it uses the secondary mouse
button.
Playing a CD or DVD
Optical storage has become the preferred medium for software, music, and
video. Digital versatile discs (DVDs) provide a significant increase in data
storage and support features that are not available on any other video
platform. These features include wide-screen movies, multiple language
tracks, digital surround sound, multiple camera angles, and interactive
menus.
For these reasons, your computer may come with a DVD-ROM or
multi-function drive.
