So my kid spills OJ into my MacBook Pro keyboard. I think it's fried, but I took the battery out, unscrewed the back case cover, and left it in the spare room to dry out overnight. I wiped up what I could see, blew compressed air as much as I could into the keyboard, etc. It's not powering up now, but one tiny bit of moisture on the motherboard and that's what would happen.
Only two years old, but the optical drive isn't working, and the computer doesn't really owe me anything, it got pretty well used and abused over the past couple of years. Got this new MacBook Air just in time.
We'll see if it dries out and comes back to life.
Curious to see if that fried laptop has resale value for the parts. The displays on those things aren't cheap. I figure somebody might buy it just for that.
