NAME

       powernap - have the system "take a power nap"; this can be a user defined ACTION_METHOD in
       /etc/powernap/config among [best-effort, suspend, hibernate, poweroff, powersave]

DESCRIPTION

       powernap will run when powernapd(8) has determined  that  an  action  needs  to  be  taken
       according  to  its  configured  parameters.  The  action  to be taken, among [best-effort,
       suspend, hibernate, poweroff], is determined  in  /etc/powernap/config.  By  default,  the
       action will be best-effort.

       When the ACTION_METHOD is best-effort, and if the file /etc/powernap/action is executable,
       then the powernap binary will run it when called. Otherwise, powernap will run one of:
         * pm-suspend
         * pm-hibernate
         *  poweroff  depending  on  your  hardware's  capabilities,  as  determined  by   pm-is-
       supported(1).

       You may do one of:
         1) Write your own custom at /etc/powernap/action and make it executable
         2) Replace /etc/powernap/action with an executable script or binary
         3) Symlink /etc/powernap/action to some other executable script or binary

       When ACTION_METHOD is powersave, then powernap binary will execute pm-suspend.

       When ACTION_METHOD is powersave, then powernap binary will execute pm-hibernate.

       When ACTION_METHOD is powersave, then powernap binary will execute poweroff.

       When  ACTION_METHOD  is powersave, then powernap binary will execute pm-powersave and pass
       an argument (true) to execute all the available scripts at /usr/lib/pm-utils/power.d/  and
       /etc/pm/power.d/. The latter will contain scripts shipped with powernap.
