Basics

Here are some basic points about keeping your computer functioning properly:

•Keep your computer in a clean, dry environment. Make sure it rests on a flat, steady surface.

•Do not place items on top of the monitor or cover any of the vents in the monitor or computer. These vents provide airflow to keep your computer from overheating.

•Keep food and drinks away from all parts of your computer. Food particles and spills might make the keyboard and mouse stick and unusable.

•Do not get the power switches or other controls wet. Moisture can damage these parts and cause an electrical hazard.

•Always disconnect a power cord by grasping the plug, but not the cord.
