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.

during normal operation.

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.

CDs or DVDs, try cleaning the disks.

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