My MacBook doesn't turn on, but HDD runs when plugged in.
I bought a 13"MacBook Unibody model A1278 on Ebay. The previous owner told me, that he wanted to remove one of the black rubber things from the bottom with a screw driver. While doing that, he managed to damage the displaycable underneath it. Now I tried to just start the computer, but nothing happens, only when I plug it into a wall ac outlet, the HDD starts to turn although I don't press any buttons.
Other than that the battery charges when plugged in and the Logicboard gets a litte warm.
Under the broken displaycable there is a small scratch (it is really small and not deep, I nearly don't notice it with my finger), can this be a problem?
