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

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

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

       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.

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

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

           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.

       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.

       hald(8), pm-suspend(8), s2both(8)
