I replaced the trackpad on my MacBook Pro 13inch early 2011. I'm not sure I disconnected the battery before I took the screws out that keep the battery in. I replaced the trackpad and the battery, and now my macbook won't turn on!! I did smell a faint burnt smell while I was doing all of this if that matters. The battery indicator lights do not turn on. The power adaptor is a very dim green. I tries an SMC reset and nothing happened. There is no activity whatsoever! Anyone have any idea what's going on?
