Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer's electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface on the computer chassis. As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated. You can also take the following steps to prevent damage from electrostatic discharge (ESD): When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body. When transporting a sensitive component, first place it in an antistatic container or packaging. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads. The following notice may appear throughout your Dell documentation to remind you of these precautions: For comfort and efficiency, observe the following ergonomic guidelines when you set up and use your computer system: Position your system so that the monitor and keyboard are directly in front of you as you work. Special shelves are available (from Dell and other sources) to help you correctly position your keyboard. Set the monitor at a comfortable viewing distance (usually 510 to 610 millimeters [20 to 24 inches] from your eyes). Make sure that the monitor screen is at eye level or slightly lower when you sit in front of the monitor. Adjust the tilt of the monitor, its contrast and brightness settings, and the lighting around you (such as overhead lights, desk lamps, and the curtains or blinds on nearby windows) to minimize reflections and glare on the monitor screen. x
