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.
