So my friend runs into my dorm room and his pocket somehow catches onto my macbook. At the last second, I come into the room only to see the macbook flying through the air and crashing onto the floor. Let's just say that this happened relatively late, and I woke everyone up on dorm with the scream that came out of my mouth. I've tested it (it was on when it fell), and remarkably, the only thing that seems to be wrong with it is the monitor (the hard drive seems to be in one piece since it still boots up), which is totally useless at this point. My buddy, being the good friend he is, has promised paying for the repairs. Does anyone know how much it will cost to replace the monitor on a macbook? Also, I've had this problem with my superdrive (I've read that it has something to do with the software for it, I haven't been able to burn a disc since I bought) and I have been meaning to take it in, will this whole monitor thing void my warranty?
