i dropped my mbp the other day, i tripped and hit my backpack on the ground. to my surprise it dented (i had it in my backpack, and inside the incase softcase) so on the bottom right corner right above the cd drive a piece of metal bulges out. its not that big of a deal and hardly noticable but i seen some dirt in it today so i went down to blow in it. when i did i got a sort of zap on my lip when it touched my computer. it was very subtle but i put my lip there again and it zapped it again. has this been reported before?
