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. (Note that UPower does not use this.)

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

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

       --suspend-hybrid
	   Test whether hybrid-suspend is 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.
