Hi Benjamin Wynne,
function keys are working ok only with kernel 4.12 (with which among other problems wifi doesn't work too).

On my laptop with Windows 10 charging sometimes stops at 95% or 97% with the notification "Plugged in not charging", and sometimes it goes to full 100%. With Ubuntu I have "charging", or most of the time "Battery (estimating...)". Here's what I believe is a correct explanation:
https://rog.asus.com/forum/showthrea...n-Not-Charging
"This is 100% normal, standard behaviour for all laptops that I have seen in the past 5 years. What you described in your post sounded more like your battery not charging at all, just discharging. What's actually happening is your computer using a standard method of battery preservation and Windows knows this, which is why it's telling you that it's plugged in but not charging - simply because it does not need to. You should actually worry about your battery being at 100%, not about it being at less than that.
The idea is that once the battery hits around 95-98% charge, charging stops in order to prevent battery life loss as these batteries should not be charged to full. This is controlled by the built-in power/energy controller. Once it hits that point the battery begins being trickle charged, just enough to keep it at a steady level. Otherwise you would see the battery drop to 97, 96, 95 etc as each day passes by. Your battery continues to be charged extremely slowly to keep it at 98% until you actually use the battery.
In order to make sure your battery will last as long as possible, fully discharge it once a month. It'll last years.
You were almost going to try "fixing" your 100% functional battery, heh.
At least you spared yourself the laugh the tech people would have given you at the computer store.
You have nothing to worry about."
