Caring for Your Computer • Place liquids away from your computer to avoid spills, and keep your computer away from water (to avoid the danger of electrical shock). • Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags. • Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers (within 13 cm or 5 in). • Avoid subjecting your computer to extreme temperatures (below 5°C/ 41°F or above 35°C/95°F). • Some appliances, such as certain portable desktop fans or air purifiers, can produce negative ions. If a computer is close to such an appliance, and is exposed for an extended time to air containing negative ions, it may become electrostatically charged. Such a charge may be discharged through your hands when you touch the keyboard or other parts of the computer, or through connectors on I/O devices connected to it. Even though this kind of electrostatic discharge (ESD) is the opposite of a discharge from your body or clothing to the computer, it poses the same risk of a computer malfunction. Your computer is designed and manufactured to minimize any effects of electrostatic charge. An electrostatic charge above a certain limit, however, can increase the risk of ESD. Therefore, when using the computer close to an appliance that can produce negative ions, give special attention to the following: - Avoid directly exposing your computer to the air from an appliance that can produce negative ions. 3
