M15 R2, battery failure & replacement
Hello all,
A month ago while i was playing Warzone with my Alienware M15R2 suddenly the fps drop from 60-80 to 15-20.I noticed the lit from the back side of my laptop was a bit high and the battery was swollen.I turned the laptop off and the next day i replaced the battery with a new one. When i tried to play again the fps was still at 15-20 even in the main menu.I checked the system and nothing was damaged. Any solution?
