Ergonomic tips
Arms and hands
• When using the keyboard and touchpad, the shoulders should
be relaxed. The upper arm and forearm should form an angle
that is slightly greater than a right angle, with the wrist and
hand in almost a straight line.
• Use a light touch when typing or using the touchpad and keep
the hands and fingers relaxed. Avoid rolling the thumbs under
your palms or supporting the wrists on the desk while typing.
• Use an external keyboard and mouse when using the
computer for long periods. When using an external keyboard
and mouse, position the devices at the same height as the
computer and within comfortable reach.
