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
