Ergonomic Considerations
You will be using your notebook computer as a portable device in a
variety of environments. Whenever possible, you should attempt to
apply the following ergonomic considerations to both stationary and
portable environments.
❑ 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.
❑ Furniture and posture – Sit in a chair with good back support and
armrests. Adjust the level of the chair so your feet are flat on the floor.
A footrest may make you more comfortable. Sit in a relaxed, upright
posture and avoid slouching forward or leaning far backward.
❑ Viewing angle of the computer’s display – Use the display’s tilting
feature to find the best position. You can reduce eye strain and muscle
fatigue by adjusting the tilt of the display to the proper position.
Adjust the brightness setting of the display also.
