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.
1 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.
