Using Your Computer
Working in Comfort with a Notebook PC
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.
