Shut down and turn off your computer (see "Turning Off Your Computer"

on page 161).

Disconnect any attached devices from the computer and from their

electrical outlets.

Remove any installed batteries (see "Battery Performance" on page 59).

Moisten a soft, lint-free cloth with water, and wipe it gently across the

NOTICE: Disconnect the mouse from the computer before cleaning the mouse

If your screen cursor skips or moves abnormally, clean the mouse.

Cleaning a Non-Optical Mouse

Clean the outside casing of the mouse with a cloth moistened with a mild

cleaning solution.

Turn the retainer ring on the underside of your mouse counterclockwise,

and then remove the ball.

Wipe the ball with a clean, lint-free cloth.

Blow carefully into the ball cage or use a can of compressed air to dislodge

dust and lint.

If the rollers inside the ball cage are dirty, clean the rollers with a cotton

swab moistened lightly with isopropyl alcohol.

Recenter the rollers in their channels if they are misaligned. Ensure that no

fibers from the swab are left on the rollers.

Replace the ball and retainer ring, and turn the retainer ring clockwise

until it clicks into place.
