3-6. 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
> >
