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 DeviceKit-power 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.
