Using Your Computer for the First Time 13
•
Do not remove the memory-module compartment door,
or try to install a memory module when the computer is
on. (See Figure 3 for the location of the door.)
(For information on installing memory modules, see
“Memory Modules” on page 88.)
•
Set up your computer work area to avoid physical strain.
Sit with your back straight and supported by your chair.
Adjust your chair or work table so that your arms and
wrists can remain in a relaxed position, parallel with the
floor. Avoid bending or twisting your wrists as you
work. Your hands should “float” slightly above the
keyboard. Refer to a book on office ergonomics for more
information on setting up your work area.
•
Take frequent breaks from working at the computer to
rest your eyes and stretch your muscles.
•
Remember to save your data files frequently and to make
backup copies of your files.
Traveling with Your Computer
If you are traveling by airplane, follow these tips:
•
Take the computer with you as carry-on luggage. Do not
check the computer with your baggage.
•
Allow the computer and disks to go through the
X-ray security devices. Do not hand-carry disks through
the walk-through metal detectors, which can cause loss
of data.
•
Make sure that the battery is charged or the AC adapter
is easily accessible. You may be required to turn on the
computer for airport security personnel.
•
Be prepared to turn off the computer during take off and
landing.
•
Contact your airline for information about using an
optional airline adapter to power your computer while
traveling by airplane.
