Description:

		The /sys/power/state file controls the system power state.

		Reading from this file returns what states are supported,

		which is hard-coded to 'standby' (Power-On Suspend), 'mem'

		(Suspend-to-RAM), and 'disk' (Suspend-to-Disk).

		which is hard-coded to 'freeze' (Low-Power Idle), 'standby'

		(Power-On Suspend), 'mem' (Suspend-to-RAM), and 'disk'

		(Suspend-to-Disk).



		Writing to this file one of these strings causes the system to

		transition into that state. Please see the file
