The acpiconf
utility allows the user control of the ACPI
power management functions. The following command-line options are recognized:
-h
- Displays a summary of available options.
-i
batt
- Get design information and current status of the battery specified by its
number, starting with
0
.
-k
ack
- Ack or abort a pending suspend request using the argument provided.
Most users should not use this option directly.
-s
type
- Enters the specified sleep mode. Recognized types are
1
(only the CPU clock is stopped),
2
(not implemented on most systems but similar to
S1), 3
(the CPU context is lost and memory context
is preserved), and 4
(the CPU context is lost and
memory context is stored to disk). Sleep states may also be given as S1,
S2, etc. The supported states depend on BIOS implementation, including
ACPI byte code (AML). If the /etc/rc.suspend and
/etc/rc.resume scripts are executable, they will
be run by
devd(8)
or
apmd(8)
before and after entering the given sleep state.
The /etc/rc.resume script uses the
rcorder(8)
utility to call scripts in /etc/rc.d/ and the
$local_startup directories that have a
"resume" KEYWORD. Called scripts are supplied with single
"resume" command line argument. See
rc.conf(5)
for more information about $local_startup.
The acpiconf
utility appeared in
FreeBSD 5.0.
