I went to the genius bar to have my trackpad replaced, because it stopped clicking well. When I got it back I noticed that my computer would randomly turn off. They ran all their hardware tests when I revisited them and they said they can't figure out what the problem is, because everything reads okay. I think the dude messed something up when working in my computer. Any ideas what he could have done when replacing my trackpad that would cause this issue? I have a 2010 core i7 macbook pro and regret for not replacing the trackpad myself.
