Power Safety
The computer has specific power requirements:
•When you want to unplug the power cord, be sure to disconnect it by the plug head, not by
its wire.
•Make sure the socket and any extension cord(s) you use can support the total current load
of all the connected devices.
•Before cleaning the computer, make sure it is disconnected from any external power sup-
plies.
Do not plug in the power
cord if you are wet.
Do not use the power cord if
it is broken.
Do not place heavy objects
on the power cord.
