❑

Check that the mouse is plugged securely into the Mouse port.

❑

Save and close all open applications. Turn off your computer, wait 
approximately 10 seconds, and then restart your computer.

❑

If you are using an optical mouse, use an appropriate surface to ensure 
optimum mouse tracking. A good mouse surface requires a certain amount 
of detail or texture to enable mouse tracking.

❑

Use surfaces such as plain paper, card stock, or fabric that do not have a 
lot of repetitive patterning.

❑

Avoid surfaces such as mirrors, smooth glass, or magazines.

❑

There may be dust or dirt inside the mouse mechanism. To clean the mouse, 
follow these steps:

Save and close all applications, and turn off your computer.

Turn the mouse upside down.

Remove the mouse ball cover on the back of the mouse by turning 
clockwise the ring that covers the mouse ball.

Turn the mouse upright, and drop the mouse ball into your hand.

Using a piece of tape, remove any dust or dirt on the mouse ball and 
inside the mouse ball socket.

Return the mouse ball to the socket, and replace the mouse ball cover. 
Secure the cover by turning the ring counter-clockwise.

You may need to reinstall the mouse drivers. See “Reinstalling device drivers using 
Application Recovery CD(s)” for more information.
