Water Damage

I would strongly second kaz-k recommendations to both leave your notebook powered-off and taking it in to have it looked at. Whatever you do, don't be fooled into thinking placing the notebook in rice or any other form of absorbent material will remove the water effectively.

Hi,

Don't switch on and make Genius Bar reservation or take your MacBook to Apple authorized service provider to check it up.

Remember that water or liquid damage isn't covered by warranty.
