Cleaning the

connected equipment.

buildup from the vents and the I/O ports on the sides
and back of the system.

Cleaning the Keyboard and
Trackball
Debris particles and oil can accumulate on, between, and
beneath the keys of your keyboard and trackball.
1 Gently use a small battery-powered vacuum to
remove debris particles that get between and
beneath the keyboard keys. Use a low setting to
avoid removing key caps and springs.
2 Use a clean, dry cloth and isopropyl alcohol to clean
the buildup on the keyboard keys.
3 Rotate the trackball-cover ring counter-clockwise to
remove the ring and release the trackball.
4 Rinse the trackball and cover ring with soap and
warm water. Dry them with a lint-free cloth.
5 Clean the rollers for the trackball with a cotton swab
dampened with isopropyl alcohol.
6 Replace the trackball and trackball-cover ring.
