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. (Note that UPower does not use this.)
17

OPTIONS

19       --suspend
20           Test whether suspend is supported. Suspend is a state where most
21           devices are shutdown, except for RAM. This state still draws power.
22
23       --hibernate
24           Test whether hibernate is supported. During hibernate the state of
25           the system is saved to disk, the system is fully powered off.
26
27       --suspend-hybrid
28           Test whether hybrid-suspend is supported. Hybrid-suspend is the
29           process where first the state of the system is saved to disk --
30           just like with hibernate -- but instead of poweroff, the system
31           goes in suspend state, which means it can wakeup quicker than for
32           normal hibernation. The advantage over suspend is that you can
33           resume even if you run out of power. s2both is a hybrid-suspend
34           implementation.
35

RETURN VALUE

37       The result of the test for a certain powermanagement state is defined
38       by the following exit codes.
39
40       Code   Diagnostic
41       0      State available.
42       1      State NOT available.
