Following problem. I went on a trip, turned off my Surface Pro 2 by shutting it down, then put it in the sleeve and in my backpack. For some reason it happened twice now that it turned on by itself and after getting it out of the bag the battery drained and its too hot to touch. I might have the feeling that the powerbutton could of been pushed by accident from moving around in the backpack. With other Tablets I owned they only turn on when holding down the powerbutton for at least 2 seconds, but the Surface already turns on by tapping the powerbutton for a milisecond. Is there a way to prevent or change this ? It'd be nicer to have that it only turns on when holding it down for a certain amount of time.
