Computer Basics
Cables
Make sure that:
• Cables are not strained and that there is no risk of people walking or
tripping over them.
• Other devices do not crush the cables.
• The power cable is connected to the computer before connecting the
power cable to the AC power outlet.
• The power cable is unplugged from the power outlet before
disconnecting the power cable from the computer.
• Three-pin power cords are connected to a grounded power outlet.
• The power outlet is easily accessible and as close to the computer as
possible (do not overload it with too many adapters).
If your computer uses an external AC adapter:
• Do not cover or place objects on the AC adapter. Allow the adapter to
cool properly during use by keeping it clear of objects.
• Only use the AC adapter that is supplied with your computer. Although
other adapters may look similar, using them can damage your computer.
If a replacement is required, use only parts certified for use with your
computer.
Cleaning your computer
• Always unplug your computer from the power outlet before cleaning it.
• Do not use liquid or aerosol cleaners, use a damp cloth instead.
• Never spray cleaning product directly on the screen.
