My gaming laptop can run most games from 60 fps to 120 fps. But recently i have noticed that when I boot my laptop when it boots and i open a game it is really laggy and unplayable going at around 4 fps. But when my laptop dies and i charge it it goes back to the normal 60-120 FPS. Why does my laptop just lag sometimes and not other times. If i play 2 hours and i stop close the game to take a break. Once i open up the game again it is unplayable please help
