I bought my laptop one year ago, I installed Windows 10 and it was great. The battery lasted 3 hours before I had to charge it again. But recently I installed Ubuntu and now it barely lasts 1 hour. When it reachs 40-50% it kinda shuts down. The screen goes black but the fans start spinning like crazy and it only happens on Ubuntu. Does anyone knows how to solve it?
