I've had this laptop for about a year and a half now and this problem just started happening. The first time I turn my laptop on for the day and try and play any game, the laptop acts as if it's not plugged in so my FPS suffers. (It says the battery is charging, the game is using the correct GPU while this happens) the only way I was about to fix this is to unplug the charger from the computer and plug it back in, then the frames shoot up and it acts normal. I have everything set to 'Max Performance'. I've tried a different charger and this still happens. I cant get it to recreate the issue either. this only happens when the computer has been off over night and turned back on for the first time. If I just shut my laptop off or put it to sleep after it's been on this issue wont happen.
