Cleaning the mouse

This section provides instructions on how to clean an optical or non-optical mouse.

Optical mouse

An optical mouse uses a light-emitting diode and an optical sensor to navigate the pointer. If the pointer on the screen does not move smoothly with the optical mouse, you might need to clean the mouse.

To clean the optical mouse, do the following:

1.Turn off your computer.

2.Disconnect the mouse cable from the computer.

3.Turn the mouse upside down to check the lens.

a.If there is a smudge on the lens, gently clean the area with a plain cotton-tipped swab.

b.If there is debris in the lens, gently blow the debris away from the area.

4.Check the surface on which you are using the mouse. If you have a very intricate picture or pattern beneath the mouse, it may be difficult for the digital signal processor (DSP) to determine changes in the mouse position.

5.Reconnect the mouse cable to the computer.

6.Turn your computer back on.
