     acpiconf — control ACPI power management

     acpiconf [-h] [-i batt] [-k ack] [-s type]

     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 about the specified battery.

     -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.
