Chapter 2. Taking care of your ThinkPad computer Though your computer is designed to function reliably in normal work environments, you need to use common sense in handling it. By following these important tips, you will get the most use and enjoyment out of your computer. Important tips Be careful about where and how you work v When your computer is turned on or the battery is charging, the base, the palm rest, and some other parts may become hot.
Taking care of your ThinkPad computer v 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.
Taking care of your ThinkPad computer Handle storage media and drives properly v If your computer comes with a diskette drive, avoid inserting diskettes at an angle and attaching multiple or loose diskette labels, as these can lodge in the drive. v If your computer comes with an optical drive, do not touch the surface of a disc or the lens on the tray. v Wait until you hear the CD or DVD click into the center pivot of an optical drive before closing the tray.
Taking care of your ThinkPad computer v Store your external and removable hard disk, diskette or optical drives in the appropriate containers or packaging when they are not being used. v Before you install any of the following devices, touch a metal table or a grounded metal object. This action reduces any static electricity from your body. The static electricity could damage the device.
Taking care of your ThinkPad computer Note: Avoid spraying cleaner directly on the display or the keyboard. Cleaning your computer display 1. Gently wipe the display with a dry, soft lint-free cloth. If you see a scratch-like mark on your display, it might be a stain transferred from the keyboard or the TrackPoint® pointing stick when the cover was pressed from the outside. 2. Wipe or dust the stain gently with a soft, dry cloth. 3.
