       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. (Note that UPower does not use this.)

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

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

           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

       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), UPower(7)
