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.
