Hello all I just bought a used G73JH-RBBX09 from a friend who purchased it from Best Buy in October. He seldomly used it and I got it for only $700. My question is does the Asus warrenty go with the itiem or did it lose it when the laptop changed hands?

Also the screen has either black pixils and or dust/dirt trapped inbetween the screen. Is their anyway this cac be cleaned out easily and effectivly with out damage to the screen if not what are the average cost of replacing the screen if it is dead pixils and they get worse I can se atleast 3-4 black spots.
