Maybe it's warm in there, and he was cold But you don't want him to get fried when that beast of a GPU kicks in, so I'd be switching your laptop off, saying goodnight to your new friend, and hoping he moves out by morning when he finds it really isn't that nice a place to live.
I saw a lady bag get in the laptop. I am afraid it will leave traces of its sticky stuff on the electronics.
Not sure if it is a good idea about just leaving it there. Any comments?
