Last night, I dropped half a pint of water mixed with orange over my MacBook Air. I turned it off and left it over night, at first it wouldn't charge, but after leaving it a few more hours, it's switched on and charging, however the fans are at 100% as soon as it's switched on and it's extremely laggy. It took a good few minutes to login. The zoom function on the dock just looks like stop-motion. It will have a minute or two where the fans go back to normal and there's no lag and it's perfect, then the fans will kick back in at 100% and it goes straight back to lagging. I've checked the cpu temperature, and the fans shouldn't be anywhere near 100%. It doesn't look like the cpu is overheating. Any ideas?
