Ergonomic Considerations

You will be using your notebook computer as a portable device in a variety of
environments. Whenever possible, you should attempt to take account of the
following ergonomic considerations to both stationary and portable environments:
Arms at desk
level
Wrists relaxed and flat
Position of your computer – Place the computer directly in front of you as you
work. Keep your forearms horizontal, with your wrists in a neutral, comfortable
position while using the keyboard, touchpad, or external mouse. Let your upper
arms hang naturally at your sides. Take breaks during sessions with your
computer. Excessive use of the computer may strain muscles or tendons.
