CHAPTER 3: Setting Up and Getting Started
Working safely and comfortably
Before using your notebook, follow these general guidelines for setting up a safe and comfortable work area and avoiding discomfort and strain:
•Keep hands and arms parallel to the floor.
•Adjust the screen so it is perpendicular to your line of sight.
•Place your feet flat on the floor or on a footrest.
•Although notebooks are sometimes called “laptops,” do not use your notebook while it rests on your unprotected lap. Notebook operating temperatures can become quite high, increasing the risk of burns to your legs. Instead, use a laptop desk to protect your legs.
•Do not use the notebook on any soft, conforming surface, such as your lap, a blanket, carpet, or a sofa. Soft surfaces can block your notebook’s ventilation openings, leading to overheating, permanent damage to your notebook, and fire danger. Instead, place your notebook on a rigid, hard surface, and make sure that you keep the ventilation openings on the sides clear.
Warning
Do not use your notebook on a soft surface, such as your lap, a blanket, carpet, or a sofa. You must keep your notebook’s ventilation openings clear of obstructions, or your notebook may overheat, increasing the risk of fire and personal injury.
Reducing eye strain
Sunlight or bright indoor lighting should not reflect on the screen or shine directly into your eyes.
•Position the computer desk and screen so you can avoid glare on your screen and light shining directly into your eyes. Reduce glare by installing shades or curtains on windows, and by installing a glare screen filter.
•Use soft, indirect lighting in your work area. Do not use your notebook in a dark room.
•Avoid focusing your eyes on your screen for long periods of time. Every 10 or 15 minutes, look around the room, and try to focus on distant objects.
•Where feasible, keep your head vertical while looking at the screen. If you use an external keyboard, raise the notebook so the top of its screen is no higher than eye level.
