I got my MacBook out of my desk this morning and the top of the book looks like it was melted. I had it plugged in over night and the power cord was laying on top of it. When I picked up the cord it was not hot...so not sure if that is what caused it. It is basically bubbled up in parts on the top, a little on the key board and a little on the bottom. Is this what it looks like when something spills on it? Just trying to figure out what the issue is and if it will be covered under the 3yr warranty or not. Thank you
