Forearms, Wrists, And Hands - HP Compaq Presario,Presario 1515 Supplementary Manual

Even if you use your keyboard in a seemingly comfortable place such as a sofa, bed,
or your favorite lounge chair, you can still cause discomfort by sitting in an awkward
position or in one position for long periods. Remember to frequently make changes to
your position, within your comfort zone, and to take short breaks.
When working on a keyboard on your lap, keep your forearms, wrists, and hands
comfortably aligned with each other in a straight, neutral line. Avoid bending or
angling your wrists. If your keyboard has palm rests, use them during pauses, not
while typing or using a pointing device.

Experiment with positioning pillows under your
forearms; they may help keep your shoulders relaxed and
your wrists straight.
