Using a laptop is often a trade-off between poor neck/head posture and poor hand/wrist posture. What type of laptop computer user are you? This means that you need to pay special attention to how you use your laptop because it may cause you problems. Consequently, laptops are excluded from current ergonomic design requirements because none of the designs satisfty this basic need. The reason is simple: with a fixed design, if the keyboard is in an optimal position for the user, the screen is not, and if the screen is optimal, the keyboard is not in an optimal position. By the late 1970s a number of ergonomics design guidelines were written and all called for the separation of screen and keyboard. In the early days of personal computing, desktop devices integrated the screen and keyboard into a single unit, and this resulted in widespread complaints of musculoskeletal discomfort. The design of laptops violates a basic ergonomic requirement for a computer, namely that the keyboard and screen are separated. Whatever input devices you choose to use, position the device comfortably and ensure that your wrist is in a neutral position when using it. Use an external mouse and keyboard to prevent wrist deviation and overreaching. If you are a full-time laptop user, you should place you laptop on a rise so that the screen is at eye-level. It can also be placed on an angled platform to the side of the keyboard. The best location for a mouse is on a platform just above the keyboard's number pad.
