While making dinner this eve. I accidently spilled a bit of water on my macbook screen (it was sitting open). I hastily wiped it off, but some water dripped down into the part where the screen ends and the plastic covering begins. Where the little lip is. I went to get on the computer later and noticed a little discoloration in the corner where the spill dripped. Is my screen ruined? Or if I turn it off and let it sit will it dry out and be back to normal again? HELP!
