ACPIPMTR(4)             NetBSD Kernel Interfaces 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 avail-
     able through the envsys(4) API and the envstat(8) command.
