This is a little late, maybe, but I did this when I spilled tea onto my laptop.
As soon as I realized what happened I flipped it on its side and most of the tea poured out from the keys. I was young enough to go to my parents (since it was kind of theirs… and they both work with computers.)
We forced it off with the power key, had it on its side to keep draining any risidual, and then very carefully and cautiously exposed the back part of the computer, plastic off, to a fan on low settings. It’s the inside that you need to worry most about getting wet, but it’s also the inside that’s most fragile in being exposed to things. We didn’t touch it or bump it, and had it set up in a safe, stable place.
Then we did what @marinelife‘s article did. We waited. But since my parents were a little paranoid, we waited for a day (a day while the rest of the family was not so happy with me) before we tried our moment of truth.
It turned on just fine, too.
The worst that happened was that the sugar (young enough to still need sugar in tea) had kinda crystalized under some keys we had to press extra hard for a while. That, and the rest of the family to this day doesn’t trust me with drinks around computers… hehe.
