ACPI(8)                                                   ACPI(8)

     NAME
          acpi - Advanced Configuration and Power Interface

     SYNOPSIS
          (in plan9.ini) *acpi=

          aux/acpi [ -m mountpoint ] [ -s service ]

     DESCRIPTION
          Aux/acpi presents at mountpoint (default /dev) an interface
          to the ACPI. If a service is specified, the interface will
          be posted at /srv/service as well.

          The directory contains the following files.

          battery
               Contains one line for each battery in the system.  Each
               line lists 12 fields: the percent charge remaining,
               power unit used (mW or mA), remaining capacity, last
               full charge capacity, design capacity, warning and low
               capacity values, mV separator, present voltage, design
               voltage, approximate time of charge left as hh:mm:ss,
               and the status (a string, one of unknown, critical,
               discharging or charging).

          cputemp
               Each line provides a current temperature reading of a
               specific CPU.

          pmctl
               Writing power off to pmctl will turn off the power.
