Important Safety Information
The only way to disconnect power completely from your computer is to unplug the
power cord from the main power supply. To disconnect your display completely, you
must also unplug its power cable from the computer or power outlet. Make sure that
at least one end of the device’s power cord is within easy reach so that you can unplug
the computer or display when necessary.
For your own safety and that of your equipment, always take the following
precautions.
Disconnect the power plug (by pulling the plug, not the cord), from your computer or
display and disconnect the phone cord if any of the following conditions exists:
 The power cord or plug becomes frayed or otherwise damaged
 You spill something into the case
 Your computer or display is exposed to rain or any other excess moisture
