I dropped my brand new, less than a month old, 13-in Macbook Pro recently when I was visiting Hong Kong. [email protected]#$%. After inspecting it carefully, I noticed it has a dent in the upper right corner of the upper body aluminum cover that's barely perceptible... but it bugs me. Is there any way to replace this cover? And would anyone know how much it would cost? I heard that for the old plastic Macbooks, the upper case costs just P1k. Also, does this dent invalidate my warranty? Thanks a lot!
