Hi, my laptop slows down a lot when it's plugged in and stutters on games it should easily be able to play. The rated charger for it is 45w, I am currently using a 65w charger and still the same issue. I've tried everything but to no use. My brother has the exact same type of laptop but doesn't have any issues. I'm pretty sure it's a software-related issue. Everything is up to date. Thanks.
