Caring for Your Computer
•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.
–Keep your computer and peripherals as far as possible from such an appliance.
–Wherever possible, ground your computer to facilitate safe electrostatic discharge.
Note: Not all such appliances cause a significant electrostatic charge.
Be Gentle with Your Computer
•Avoid placing any objects (including paper) between the display and the keyboard or under the keyboard.
•Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects on your computer, display, or external devices.
Carry Your Computer Properly
•Before moving your computer, be sure to remove any media, turn off attached devices, and disconnect cords and cables.
•Be sure your computer is in sleep or hibernation mode, or turned off, before moving it. This will prevent damage to the hard disk drive and data loss.
•When picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by the display.
•Use a quality carrying case that provides adequate cushion and protection. Do not pack your computer in a tightly packed suitcase or bag.
