ACPIBAT(4)              NetBSD Kernel Interfaces Manual             ACPIBAT(4)

NAME
     acpibat -- ACPI Control Method Battery

SYNOPSIS
     acpibat* at acpi?

DESCRIPTION
     The acpibat driver supports ACPI Control Method Battery.

     The status can be monitored by envsys(4) API or envstat(8) command.

EVENTS
     The acpibat driver is able to send events to powerd(8) when capacity
     state has been changed. The new state will be reported as the fourth
     argument to the /etc/powerd/scripts/sensor_battery script. If a custom
     capacity limit was set via envstat(8), the acpibat driver will report a
     user-capacity event to the same script when current capacity limit has
     been reached.

HISTORY
     The acpibat driver appeared in NetBSD 1.6.

BUGS
     Smart Battery Specification-based batteries are not supported.
