Thank you!!! (plus a tip that might help someone else)
About 6 weeks ago, I was drinking a diet soda and fell asleep on my macbook air (mid 2012). Narcolepsy is awesome. Anyway, I woke up hours later to the soda can lying over the keyboard (laptop still plugged in and running), and when I picked it up liquid was dripping from the bottom. Sat it on a pillow and enough ran out the bottom to soak a 12" circle on it. I hopped on here on my phone to see what I should do (still hadn't unplugged it), read for a bit, and freaked out. I unplugged and powered down, sat the mac-teepee over a towel, and held a hair dryer to one side (with my hand in front and on the cooler cycle to be sure I wasn't going hot).
I turned it back on after about 3 intermittent hours of the blowdryer and about 12 hours total in a room beside a dehumidifier. It made horrifying noises, weird screen with symbols, and the charger mag wouldn't even register that it had plugged to the laptop. Thought for sure it was a total goner, and started online shopping for a replacement.
Turned it back on after a few meltdowns about the cost of a new one, and somehow it worked perfectly without a hitch, and has ever since. I have no idea how I got that lucky. Had I not read this and seen where some had started out acting like they were destroyed and then somehow recovered, I would have likely trashed it after the first check - especially since I think I did EVERY SINGLE THING wrong.
So, my two cents - buy a laptop stand for the crazy moments, don't drink at the mac, use cool (hand-tested) hairdryer to maybe speed up the drying, and WAIT. And even if it isn't working after you wait the full 72 hours that you really need to, give it a bit more time...maybe you'll get lucky!
