.Sh NAME
.Nm acpiconf
.Nd control ACPI power management
.Sh SYNOPSIS
.Nm
.Op Fl h
.Op Fl i Ar batt
.Op Fl s Ar type
.Sh DESCRIPTION
The
.Nm
utility allows the user control of the ACPI power management
functions.
The following command-line options are recognized:
.Bl -tag -width ".Fl s Ar type"
.It Fl h
Displays a summary of available options.
.It Fl i Ar batt
Get design information about the specified battery.
.It Fl s Ar type
Enters the specified sleep mode.
Recognized types are
.Cm 1
(only the CPU clock is stopped),
.Cm 2
(not implemented on most systems but similar to S1),
.Cm 3
(the CPU context is lost and memory context is preserved),
.Cm 4
(the CPU context is lost and memory context is stored to disk)
and
.Cm 5
(soft off).
Sleep states may also be given as S1, S2, etc.
The supported states depend on BIOS implementation, including ACPI
byte code (AML).
If the
.Pa /etc/rc.suspend
and
.Pa /etc/rc.resume
scripts are executable, they will be run before and after entering
the given sleep state.
