 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
