I am using Dell latitude e6410 which is running 16.04 The problem I am facing is that my laptop shuts down when the battery is at 65-70%. Sometimes it lasts till 10% but mostly it will shutdown when the battery is below 70%. I am not facing this issue on windows 7 though. And the battery backup is worst. I use it for 15-20 mins and it goes down to like 80%(does not happen in windows).
I used TLP but it did not help. What is the problem? How do I solve it?
