• To help protect your computer from sudden, transient increases and

decreases in electrical power, use a surge suppressor, line conditioner, or

uninterruptible power supply (UPS).

• Be sure nothing rests on your computer’s cables and that the cables are

not located where they can be stepped on or tripped over.

• Do not push any objects into the openings of your computer. Doing so

can cause fire or electric shock by shorting out interior components.

• Keep your computer away from radiators and heat sources. Also, do not

block cooling vents. Avoid placing loose papers underneath your

computer; do not place your computer in a closed-in wall unit or on a

bed, sofa, or rug.
