4 Blow carefully into the ball cage or use a can of compressed air to dislodge
dust and lint.
5 If the rollers inside the ball cage are dirty, clean the rollers with a cotton
swab moistened lightly with isopropyl alcohol.
6 Recenter the rollers in their channels if they are misaligned. Ensure that
fluff from the swab is not left on the rollers.
7 Replace the ball and retainer ring, and turn the retainer ring clockwise
until it clicks into place.
Cleaning an Optical Mouse
Clean the outside casing of the mouse with a cloth moistened with a mild
cleaning solution.
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 floppies to remove contaminants that accumulate
during normal operation.
CDs and DVDs
NOTICE:
Always use compressed air to clean the lens in the CD/DVD 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 discs.
1 Hold the disc by its outer edge. You can also touch the inside edge of the
center hole.
NOTICE:
To help prevent damage to the surface, do not wipe in a circular motion
around the disc.
