My laptop's battery started performing badly after switching to Ubuntu and unfortunately I was no longer within the warranty period so I figured I had to buy a new battery at some point. I switched back to Windows for school later on. The battery would last about 3.5/4 hours at this point, and worked like that for almost a year.
I wanted to use Ubuntu again about a week ago and after installing it my battery performed even worse, only lasting about 1 to 1.5 hours. I wondered if using Windows would at least reverse the condition but after doing that my laptop now exclusively works plugged in. Windows says "plugged in, not charging" but the charger itself isn't damaged at all. Seeing how to battery acted before it makes more sense anyway that it is in fact defect.
It seems I've undergone battery issues three times after changing OS. I've never heard anything regarding this so I was wondering if you guys might have. Could this have been the reason my battery died?
The laptop is "only" 2.5 years old and it was an expensive one at that. It seems very odd behavior. It's a Samsung Ativ Book 9 if anyone is wondering.
Thanks for reading and thanks in advance.
