ACPIPMTR(4)                  Device Drivers Manual                 ACPIPMTR(4)

NAME
     acpipmtr - ACPI Power Meter

SYNOPSIS
     acpipmtr* at acpi?

DESCRIPTION
     The acpipmtr device driver provides support for "power meters".  These
     are sensors that approximate the current power consumption of the system.
     Alternatively, a power meter may measure also the power gain when the
     system is connected to an external power supply.

     The available information (namely, the power consumption) is made
     available through the envsys(4) API and the envstat(8) command.

SEE ALSO
