The other day i tried to use my super drive and i noticed it was bowed down and i had trouble ejecting the cd. I have never dropped the laptop so don't assume its that. I understand it could be from me pressing on the palm rests but i really dont see how i could of done that but anyways i know apple won't replace it so i was planning on going my own route of replacing the bottom case. My only problem with this is that i do not want to void my warrenty. Will replacing my bottom case do that?
