I have a 6 moth old macbook that has a small crack on the edge of palm rest. The crack came about after repeatedly carrying my laptop in my backpack with heavy books. The laptop had its own compartment and it was even in an anti-shock sleeve. For those who have a Macbook, you will notice that there are two thin supports on the top of laptop that basically keeps the lcd screen off the keyboard when it is closed. Apparently, one of the supports was squashed into the palm rest, which caused a small crack. The laptop is perfectly fine otherwise but my concern is if something else should go wrong with my computer, the will use they crack as a reason not to fix it. Can they do that? I am guessing they could link every possible hardware failure to me "sabotaging" my computer.
