Ergonomic considerations
You will be using your notebook 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:
Position of your computer – Place the computer directly in front of you (1). Keep your forearms horizontal (2),
with your wrists in a neutral, comfortable position (3) while using the keyboard, touchpad, or external mouse. Let
your upper arms hang naturally at your sides. Have 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. 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 backwards.
