Public bug reported:
I did a fresh install of ubuntu 16.04.1 on an asus x556uak laptop and
noticed that when connected to AC and the battery is not charging the
system shows the battery icon as discharging , but when the battery has
discharged a little and when connected again it charges, then system
shows the battery icon as connected to AC and charging.
Also I've noticed that all though I have 2 38 Whr cells ubuntu is only
detecting one 38 Whr cell, as if the second one doesn't exist? But maybe
this is not a bug and it switches to secondary battery when the 1st one
is empty?
This is the output of `upower -d`
