Is there a bump on all PB 15's?? I have a slight protrusion sticking out of my PB "15 Superdrive, and my friend who just got a refurbished PB 15 Combo has one in the exact same place!!!! What is this all about?? The bump is right on top of the release button for the screen. You know where the light pulses when the PB is sleeping. Its small but noticeable, and u can easily feel it if u run your finger along the width of the PB. What can I do about this?? Will Apple give me a new PB or fix it at least.
