pm-is-supported

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.
