PM-IS-SUPPORTED(1)	     pm-utils User Manual	    PM-IS-SUPPORTED(1)

NAME
       pm-is-supported - Test whether suspend or hibernate is supported.

SYNOPSIS
       pm-is-supported [{--suspend | --hibernate | --suspend-hybrid}]

DESCRIPTION
       This manual page documents briefly the pm-is-supported command.

       The intended purpose of pm-is-supported is to find out which power
       management modes are supported by the system. hald(8) will call it to
       do just that.

OPTIONS
       --suspend
	   Is suspend supported? Suspend is a state where most devices are
	   shutdown, except for RAM. This state still draws power.

       --hibernate
	   Is hibernate supported? During hibernate the state of the system is
	   saved to disk, the system is fully powered off.

       --suspend-hybrid
	   Is hybrid-suspend supported? Hybrid-suspend is the process where
	   first the state of the system is saved to disk -- just like with
	   hibernate -- but instead of poweroff, the system goes in suspend
	   state, which means it can wakeup quicker than for normal
	   hibernation. The advantage over suspend is that you can resume even
	   if you run out of power. s2both is a hybrid-suspend implementation.

RETURN VALUE
       The result of the test for a certain powermanagement state is defined
       by the following exit codes.

       Code   Diagnostic
       0      State available.
       1      State NOT available.
