functionality to work (however, the kernel changes were committed to current at 1998/07/05 23:29:11 PDT). o Enable setting of a timer for later wakeup. Note, not all APM BIOSes support this for all modes (mine doesn't support waking up on a timer from standby mode). o Print out the APM capabilities, as reported by the BIOS. o Report wake on ring indication. No way to enable/disable this, but it is reported. o update man page with above o The output of this command has changed, so if you have a script that parses its output, then you may need to rewrite it slightly. o The code attempts to deal with older kernels than July 5, 1998, but that part of the code isn't well tested.

.Sh DESCRIPTION
|
|
.Nm Apm
|
|
controls the Intel / Microsoft APM (Advanced Power Management) BIOS and
|
|
displays the current status of APM on laptop PCs.
|
|
.Nm Zzz
|
|
suspends the system by controlling APM.
|
|
.Pp
|
|
The following options are available for
|
|
.Nm apm
|
|
(no options are available for
|
|
.Nm zzz
|
|
).
|
|
If no options are specified,
|
|
.Nm apm
|
|
displays information and current status of APM in verbose mode.
|
|
If multiple display options are given, the values are displayed one
|
|
per line in the order given here.
|
|
.Bl -tag -width indent
|
|
.It Fl a
|
|
Display the current AC-line status as an integer value. The values
|
|
0 and 1 correspond to the
|
|
.Dq off-line
|
|
state or
|
|
.Dq on-line
|
|
state, respectively.
|
|
.It Fl b
|
|
Display an integer value reflecting the current battery status.
|
|
The values 0, 1, 2, 3, correspond to the
|
|
.Dq high
|
|
status,
|
|
.Dq low
|
|
status,
|
|
.Dq critical
|
|
status,
|
|
.Dq charging
|
|
status respectively.
|
|
.It Fl d
|
|
Disable/enable suspending of the display separately from a normal suspend
|
|
using the values
|
|
.Ar 1
|
|
or
|
|
.Ar 0
|
|
respectively. This argument seems to not work on many different
|
|
laptops, including the Libretto 30CT and 50CT.
|
|
.It Fl l
|
|
Display the remaining battery percentage. If your laptop does not
|
|
support this function, 255 is displayed.
|
|
.It Fl r
|
|
Enable the resume wakeup timer, if the laptop supports it. This
|
|
doesn't actually suspend the laptop, but if the laptop is suspended,
|
|
and it supports resume from suspend, then it will be resume after
|
|
.Ar delta
|
|
seconds (from when you run this command, not from when you suspend).
|
|
.It Fl s
|
|
Display the status of the APM support as an integer value. The values
|
|
0 and 1 correspond to the
|
|
.Dq disabled
|
|
state or
|
|
.Dq enabled
|
|
state respectively.
|
|
.It Fl t
|
|
Display the estimated remaining battery lifetime in seconds. If
|
|
it is unknown, -1 is displayed.
|
|
.It Fl Z
|
|
Transition the system into standby mode. This mode uses less power than
|
|
full power mode, but more than suspend mode. Some laptops support
|
|
resuming from this state on timer or Ring Indicator events. The
|
|
output of apm tells what your laptop claims to support.
|
|
.It Fl z
|
|
Suspend the system. It is equivalent to
|
|
.Nm zzz .
|

.El
|
|
.Sh BUGS
|
|
Some APM implementations do not support parameters needed by
|
|
.Nm apm .
|
|
On such systems,
|
|
.Nm apm
|
|
displays them as unknown.
|
|
.Pp
|
|
Some APM implementations cannot handle events such as pushing the
|
|
power button or closing the cover. On such implementations, the system
|
|
.Ar must
|
|
be suspended
|
|
.Ar only
|
|
by using
|
|
.Nm apm
|
|
or
|
|
.Nm zzz .
