acpibat -- ACPI Control Method Battery
acpibat* at acpi?
The acpibat driver supports ACPI Control Method Battery.
The status can be monitored by envsys(4) API or envstat(8) command.
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
acpi(4), envsys(4), envstat(8), powerd(8)
The acpibat driver appeared in NetBSD 1.6.
