I have a brand new, 13-inch, 2.9 GHz i7, 8 GB RAM, 750 GB Hard Drive MacBook Pro, and I have noticed a crackling noise coming from the upper left side of the machine, I think by the charger port. It is only one crackle, and it is relatively loud. It only happens after gaming. It has happened after Minecraft, Skyrim, Gmod, all of my games. I keep my MacBook plugged in when I game, and seeing how the sound is coming from near the charger, I thought maybe that had something to do with it. Does anyone know what's going on with it?
