Preventive Maintenance

Cleaning the External Mouse

ÅWARNING: Always disconnect the power from your Notebook and disconnect any other peripherals before attempting to clean your Notebook or any of its components.

JTip Give your Notebook a safe home. If your Notebook is consistently exposed to direct sunlight, consider moving it. The heat from the sun shining on the display screen can reduce its performance and cause glare.

If you are using an external mouse and the precision control of the mouse pointer becomes difficult, cleaning the mouse can substantially improve its performance.

To clean the external mouse, complete the following steps:

1.Turn the mouse over and rotate the circular plate about 1/4-inch counter-clockwise until it pops loose. Most mice have an arrow to indicate the direction to turn the plate.

2.Remove the ball from your mouse and clean it with an antistatic wipe or a lint-free cotton cloth.

3.Spray the inside of the mouse with compressed air in an aerosol can to remove loose debris and dust.

4.Replace the ball and the bottom plate.
