Pretty sure the problem is in the on_ac_power script from powermgmt-base.
It appears to be a really simplistic script which searches through 4 
categories and I checked (with `ls -l <path>` what it would do on my Rock64:

1) /sys/class/power_supply/
total 0
(iow: that directory does exist, but is empty)

2) ACPI (through /proc/acpi/ac_adapter)
ls: cannot access '/proc/acpi': No such file or directory

3) PMU (through /proc/pmu/info)
ls: cannot access '/proc/pmu/info': No such file or directory

4) APM (through /proc/apm)
ls: cannot access '/proc/apm': No such file or directory

My guess is that it's unaware of device-tree ... which is a problem (for ARM 
devices).
