 .Sh NAME
 .Nm acpiconf
 .Nd control ACPI power management
 .Sh SYNOPSIS
 .Nm
 .Op Fl h
 .Op Fl i Ar batt
 .Op Fl k Ar ack
 .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.
+Get design information and current status of the battery specified
+by its number, starting with
+.Cm 0 .
 .It Fl k Ar ack
 Ack or abort a pending suspend request using the argument provided.
 .Sy Most users should not use this option directly.
 .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),
 and
 .Cm 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
 .Pa /etc/rc.suspend
 and
 .Pa /etc/rc.resume
 scripts are executable, they will be run by
 .Xr devd 8
 or
 .Xr apmd 8
 before and after entering the given sleep state.
 .Pp
 The
 .Pa /etc/rc.resume
 script uses the
 .Xr rcorder 8
 utility to call scripts in
 .Pa /etc/rc.d/
 and the
 .Va $local_startup
 directories that have a "resume" KEYWORD.
 Called scripts are supplied with single "resume"
 command line argument. See
 .Xr rc.conf 5
 for more information about
 .Va $local_startup .
