Basic Operation
Working in Comfort with a Notebook PC
Using Your Mobile Computer
Position the computer so your wrists and hands are in a neutral position. Your wrists
should be as straight as possible and should not have to bend sideways or more than
10 degrees up or down. If your notebook computer does not have a built-in palm rest,
you can use a rolled-up towel.
Try to type as lightly as possible. The notebook keyboard requires little force to
activate.
Take frequent, short rest breaks–this is especially important in a mobile computing
environment.
Portable computers weigh between approximately 1.4 and 3.7 kilos (3 and 8 pounds).
When traveling, be sure to carry your computer properly to minimize strain on your
body. Shift the bag containing your notebook equipment frequently between your left
and right hands and shoulders.
