33.Sh NAME
34.Nm acpiconf
35.Nd control ACPI power management
36.Sh SYNOPSIS
37.Nm
38.Op Fl h
39.Op Fl i Ar batt
40.Op Fl k Ar ack
41.Op Fl s Ar type
42.Sh DESCRIPTION
43The
44.Nm
45utility allows the user control of the ACPI power management
46functions.
47The following command-line options are recognized:
48.Bl -tag -width ".Fl s Ar type"
49.It Fl h
50Displays a summary of available options.
51.It Fl i Ar batt
52Get design information and current status of the battery specified
53by its number, starting with
54.Cm 0 .
55.It Fl k Ar ack
56Ack or abort a pending suspend request using the argument provided.
57.Sy Most users should not use this option directly.
58.It Fl s Ar type
59Enters the specified sleep mode.
60Recognized types are
61.Cm 1
62(only the CPU clock is stopped),
63.Cm 2
64(not implemented on most systems but similar to S1),
65.Cm 3
66(the CPU context is lost and memory context is preserved),
67and
68.Cm 4
69(the CPU context is lost and memory context is stored to disk).
70Sleep states may also be given as S1, S2, etc.
71The supported states depend on BIOS implementation, including ACPI
72byte code (AML).
73If the
74.Pa /etc/rc.suspend
75and
76.Pa /etc/rc.resume
77scripts are executable, they will be run by
78.Xr devd 8
79or
80.Xr apmd 8
81before and after entering the given sleep state.
82.Pp
83The
84.Pa /etc/rc.resume
85script uses the
86.Xr rcorder 8
87utility to call scripts in
88.Pa /etc/rc.d/
89and the
90.Va $local_startup
91directories that have a "resume" KEYWORD.
92Called scripts are supplied with single "resume"
93command line argument. See
94.Xr rc.conf 5
95for more information about
96.Va $local_startup .
