NAME

6       pm-is-supported - Test whether suspend or hibernate is supported.
7

SYNOPSIS

9       pm-is-supported [{--suspend | --hibernate | --suspend-hybrid}]
10

DESCRIPTION

12       This manual page documents briefly the pm-is-supported command.
13
14       The intended purpose of pm-is-supported is to find out which power
15       management modes are supported by the system. hald(8) will call it to
16       do just that.
17

OPTIONS

19       --suspend
20           Is suspend supported? Suspend is a state where most devices are
21           shutdown, except for RAM. This state still draws power.
22
23       --hibernate
24           Is hibernate supported? During hibernate the state of the system is
25           saved to disk, the system is fully powered off.
26
27       --suspend-hybrid
28           Is hybrid-suspend supported? Hybrid-suspend is the process where
29           first the state of the system is saved to disk -- just like with
30           hibernate -- but instead of poweroff, the system goes in suspend
31           state, which means it can wakeup quicker than for normal
32           hibernation. The advantage over suspend is that you can resume even
33           if you run out of power. s2both is a hybrid-suspend implementation.
34

RETURN VALUE

36       The result of the test for a certain powermanagement state is defined
37       by the following exit codes.
38
39       Code   Diagnostic
40       0      State available.
41       1      State NOT available.
