Hi, I think I found my new project. I found my old Mac book pro and turned it on and it works and also the trackpad works barely but I can still click and scroll. But the trackpad is lifted because of battery swelling. Is the swelling a safety hazard? How much will it cost to fix, I have no experience with this but don't care if I mess up (no warrenty, sidebar project). How should I fix this without damaging my mac. The picture file is too big to upload but the trackpad is like floating at an angle with parts of it normal and toward the keyboard it gets higher.
