The status of the AC adapter, battery, and fan are reported via the .Xr envstat 8 interface, and AC adapter and lid switch events are reported via the .Xr sysmon_pswitch 9 interface. .Sh SEE ALSO .Xr envstat 8 .Sh BUGS The battery status is reported by reading the battery voltage. Pp. The points at which the battery level becomes warning and critical are reported by the PMU, but are not directly correlated with battery voltage, so might be misreported by the driver.
