Green PC Function
The CommPlete 4000 is equipped with a green function that allows it
to operate using reduced electrical power when the machine is
inactive. When in green mode, the CommPlete 4000 slows down and
shuts down certain computer functions in order to reduce power
consumption. There are three reduced-power operating modes
(presented in order of increasing power savings):
(1) CPU Doze Mode,
(2) System Standby Mode,
(3) System Suspend Mode .
By default, however, the green function is turned off.
