Sounds like fallout from
http://cgit.freedesktop.org/upower/commit/?id=07b95b8e or some similar
changes. So this is an inverse kernel/hardware bug to the problem of
phone batteries from that commit. *sigh* So we need to add some more
heuristics for this case, too.
I have a pretty good idea what happens, but for avoiding mistakes and
also to add a reliable test case, can you please copy&paste the output
of "grep -r . /sys/class/power_supply/*"?
