Problem Solution

The mouse doesn’t work, even though everything else does. (continued)

■If the pointer doesn’t move on the screen when you move the mouse, clean the mouse. For an optical mouse, wipe the light sensor lens on the bottom of the mouse with a lint-free cloth. For a roller ball mouse:

1 Remove the mouse ball by unscrewing the bottom of the mouse.

2 Clean the mouse ball with a damp cloth (not paper).

3 Use your finger to move the rollers in the mouse ball housing and remove lint and dust.

4 Replace the mouse ball and screw on the cover.

■The computer might have stopped. Reset the computer by pressing and holding the computer On button until the computer turns off (approximately 5 seconds). Then turn the computer back on.
