I was having a party when someone decided to bring my macbook out to the pool, somone jumped of the diving board and it got splashed while it was on, i saw ran over and wiped it all off (there was hardly any on the key's mostly on the screen) later i noticed there was a white mark on my screen, being stupid i just turned my computer off and thought it would go away, when i turned it on about 2 hours later the water mark had gotten bigger, its been about 28 hours since the water got on the computer the battery is currently out and i have a lamp on the screen where the water is any advice?
