Computer Equipment - Care & Cleaning

Routine computer Maintenance

The following information about preventive maintenance will help you keep your computer running smoothly. You can also find tips in the User Guide that came with your equipment.\ Care of computer equipment

  • Keep the computer on a sturdy, flat surface in a clean, dry environment.
  • Do not place items on top of the monitor, or cover any of the computer or monitor vents. The vents let air flow over the equipment and keep it from overheating.
  • Keep food and drinks away from the computer. Spills and food particles can ruin the mouse, keyboard, and other equipment. Moisture on the power switches or other controls may damage the parts and create an electrical hazard.
  • Always disconnect power cords by grasping the plug, not the cord.

Periodic Cleaning

When cleaning the screen, first wipe it gently with a soft, dry cloth, or blow on it to remove grit and loose particles, and then use a soft cloth moistened with a nonabrasive liquid glass cleaner. In addition, you can use an anti-static cleaner to slow the buildup of dust.\ Mouse
