Computer has been on my desk all day plugged into the charger, used until 4pm. Shut the lid and spent some time out. Got home and grabbed it to use on the couch and the bottom / hinge side of the computer was smoken HOT. Turned it on and all seems fine? Anyone else have this issue? googled and only got one hit of the same problem over on discussion.apple.com Computer is new. Also noticed when i place the computer down slowly on a desk it makes a funky rather metallic loud tinging sound. Can replicate it by pushing in the center of the bottom cover. Not your typical creek one would expect from an aluminum/ metal case.
