SYNOPSIS
acpiac* at acpi?
DESCRIPTION
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).
