My friend is in Brazil right now and her Macbook Pro 15" just did something weird. Let me start off by saying that her laptop was plugged into magsafe, but NOT plugged into an outlet. She was using the Macbook Pro and all of a sudden she heard a pop noise, her laptop turned off, and she smelled a smokey smell. She now turned it back on and says she smells a burning smell. Any idea what this might be? Again, it wasn't plugged into the wall, so it's not a power conversion thing. I'm stumped. Her fan IS working, so it's not a broken fan.
