Cleaning Your Computer

CAUTION: Before you begin any of the procedures in this section, follow the

safety instructions in the

Product Information Guide

Computer, Keyboard, and Monitor

CAUTION: Before you clean your computer, disconnect the computer from the

electrical outlet. Clean your computer with a soft cloth dampened with water. Do

not use liquid or aerosol cleaners, which may contain flammable substances.

Use a can of compressed air to remove dust from between the keys on the

keyboard.

Floppy Drive

NOTICE: Do not attempt to clean drive heads with a swab. You might accidentally

misalign the heads which prevents the drive from operating.

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

NOTICE: Always use compressed air to clean the lens in the optical drive, and

follow the instructions that come with the compressed-air product. Never touch the

lens in the drive.

If you notice problems, such as skipping, with the playback quality of your

CDs or DVDs, try cleaning the disks.

Hold the disk by its outer edge. You can also touch the inside edge of the

center hole.

NOTICE: To avoid damaging the surface, do not wipe in a circular motion around

the disk.
