About three days ago I inserted a disc into the superdrive and watched a movie and then took it out and then for some reason the MAC was vibrating and making clicking noises. Like the noise when you move your MacBook to fast or something when using it. Eat keeps vibrating a lot and the only way to lower the vibrating is to push down to the left and right of the trackpad. Also I hear little ticking noises like the HDD is hitting something and it's just making weird noises. Then the next day I accidentally stepped on the laptop and cracked the screen in the top right of the computer. Then the next I looked at the bottom left and theres a dent. could me stepping on it make that dent? Because I never dropped my laptop. Also the vibrating and weird noises started before me stepping on the laptop. Also I noticed that the bottom right of the laptop is lifted off the table when I put it down so it's not balanced correctly and when I push it down it stops vibrating. It's just barley lifted up. could this be the problem with everything? Would anyone have an idea what the problem is? Also apple said it costs $1000 to fix the crack in the screen, but I paid $1200 to buy it new. I have a 2012 mid MacBookPro. The crack is like a hairline crack from the top left to the top right then through the screen to the middle then down to the bottom right.
