So yesterday i was listening to music on my Macbook Pro which is attached to an external monitor. Usually after 10min my Macbook Pro turns on its sceensaver. However this time it just starts flashing on and off. It looks like someone is turning on and off both my Macbook Pro's and my external monitor. This does not stop. I moved the mouse and waited again and the same thing happened.
Any idea as to while this mite be happening?
