I turned on my macbook pro today to find a giant white spot on the screen. To give an idea of its size it went from the dock on the left hand side of the screen all the way to the K in MacBook Pro. I never got any liquids near my macbook pro nor have I even cleaned the screen. I went out and bought a can of compressed air and was able to push the white spot into a smaller 4inch by 2 inch rectangle. It seems like moisture got under the screen. Please help I am at a loss of what to do here. I have it under warrenty since it is only a few weeks old but I really dont even know how to explain this to the mac people.
