Ummm, I was playing league on my acer predator and half way through the game the controls stopped working, and we lost the game, yada yada, anyway, after the game, the keyboard wasn't working and I didn't know what to do, so I restarted the laptop and through the restart, it got stuck on a black screen and won't turn off, the fan is working and the keyboard lights are on, but I can't even force shut down.
