(5) 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
