Mouse
If the pointer on the screen does not move smoothly with the mouse, you might
need to clean the mouse.
To clean your mouse, do the following:
1. Turn off the computer.
2. Disconnect the mouse cable from the computer.
3. Turn the mouse upside down. Unlock the retainer on the bottom of the
mouse by rotating it in the direction of the arrow.
Note:
Some mice have lock and unlock symbols to indicate how far you need
to rotate the retainer.
4. Place your hand over the retainer and turn the mouse right-side up. The
retainer and ball will drop out into your hand.
5. Using a damp cloth, wipe the outside of the mouse and the retainer. Be sure
to wipe the rollers inside the mouse.
6. Insert the ball and retainer. Lock the retainer by rotating it opposite the
direction of the arrow.
7. Reconnect the mouse cable to the computer.
