Overview

The acpiac driver supports ACPI AC Adapters. Information about AC power source status (connected or disconnected) is available through this driver as a sensor. AC power source status is updated via an event when a change happens, if the implementation supports it. The sensors provided by acpiac can be monitored using sysctl(8) or sensorsd(8).
