Using Your Computer for the First Time 11
• Do not remove the memory-module compartment door, or try to install a
memory module when the computer is on.
(For information on installing memory modules, see “Installing a Memory
Module” on page 68.)
• 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.
Travelling with Your Computer
If you are travelling by air, 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.
• Please collect your computer immediately after X-ray scanning, this is a high
theft area for portable computers.
• Make sure that the battery is charged or the power cord 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.
Locking your Computer
As a precaution, when you are travelling or leaving your computer unattended, you
should keep your computer as safe as possible. A way to do this is a Security Lock
System. Follow the Security Lock System manufacturer’s instructions for specific
installation and use. The figures below show generally how to use the security lock.
