Cleaning the keyboard
You should clean the keyboard occasionally by using an aerosol can of air with
a narrow, straw-like extension to remove dust and lint trapped under the keys.
If you spill liquid on the keyboard, turn off your computer and turn the unit
upside down. Let the liquid drain, then let the keyboard dry before trying to
use it again. If the keyboard does not work after it dries, you may need to
replace it.
Cleaning the screen
Use a soft cloth and water to clean the screen. Squirt a little water on the
cloth (never directly on the screen), and wipe the screen with the cloth.
Cleaning the mouse
If you have a mouse and the mouse pointer begins moving erratically across
the screen or becomes difficult to control precisely, then cleaning the mouse
will likely improve its accuracy.
If you have an optical mouse, clean the mouse by wiping the bottom of the
mouse with a cleaning cloth.
To clean your trackball mouse:
1
Turn the mouse upside down.
2
Rotate the retaining ring on the bottom of the mouse counter-clockwise.
