Tip
Give your Presario 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.
Warning
Always disconnect the
power from your Notebook
and disconnect any other
peripherals before attempting
to clean your Notebook or
any of its components.
If you are using an external mouse and the mouse pointer's
precision control 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" 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.
