This used to work before jmcneill-pm, I can't confirm now because I don't
have a laptop but I suspect the new acpiec(4) code might be related to that.

The code does that: finds all SME_CLASS_ACADAPTER and SME_CLASS_BATTERY
devices registered in sysmon_envsys(9) and if the ac adapter is off
and all batteries are in critical or low state, sends the 'low-power' event.
