The Green PC Function
The Power Management Unit (PMU) controls and dramatically reduces
overall system power consumption. This is accomplished by the activity
monitors, which detect the system inactivity timer time-out, and signals
the power-saving devices to slow down the clock frequency or remove
the power sources from various peripherals.
There are four power management modes: Normal, Doze, Standby, and
Suspend.
