Power Management Setup Menu
The difference between Green PCs and traditional computers is that Green
PCs have a power management feature. With this feature, when the computer is
powered on but inactive, the power consumption is reduced in order to save
energy. When the computer operates normally, it is in Normal mode. In this
mode, the Power Management Program will control the access to video, parallel
ports, serial ports and drives, and the operating status of the keyboard, mouse
and other device. These are referred to as Power Management Events. In cases
where none of these events occur, the system enters the power saving mode.
When one of the controlled events occurs, the system immediately returns to
normal mode and operates at its maximum speed. Power saving modes can be
divided into three modes according to their power consumption: Doze Mode,
Standby Mode , and Suspend Mode. The four modes proceed in the following
sequence:
Normal Mode===> Doze Mode===> Standby Mode===> Suspend Mode
The system consumption is reduced according the following sequence:
Normal
> Doze > Standby > Suspend
