l Moisten a soft, lint-free cloth with water and wipe the computer and keyboard. Do not allow water from the cloth to seep between the touch pad and
the surrounding palm rest.
Touch Pad
1. Shut down and turn off your computer, disconnect any attached devices, and disconnect them from their electrical outlets.
2. Remove any installed batteries.
3. Moisten a soft, lint-free cloth with water, and wipe it gently across the surface of the touch pad. Do not allow water from the cloth to seep between the
touch pad and the surrounding palm rest.
Floppy Drive
Clean your floppy drive using a commercially available cleaning kit. These kits contain pretreated floppy disks to remove contaminants that accumulate during
normal operation.
CDs and DVDs
If you notice problems, such as skipping, with the playback quality of your CDs or DVDs, try cleaning the discs.
1. Hold the disc by its outer edge. You can also touch the inside edge of the center hole.
2. With a soft, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight line from the center to the outer edge of the disc.
For stubborn dirt, try using water or a diluted solution of water and mild soap. You can also purchase commercial products that clean discs and provide
some protection from dust, fingerprints, and scratches. Cleaning products for CDs are safe to use on DVDs.

CAUTION: Before you clean your computer, disconnect the computer from the electrical outlet and remove any installed batteries. Clean your
computer with a soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain flammable substances.
