[ambrus]: 1nickt: the tea didn't have sugar or honey or lemon or milk. or even caffeine in a significant quantity. it's really "colored water", warm water with some fruit smell to make it more pleasant than ordinary warm water.
[ambrus]: 1nickt: in theory, it shouldn't hurt the electronics, but also could temporarily cause problems until it dries, and the inside of the keyboard doesn't dry quickly, because it's closed.
[ambrus]: 1nickt: that's the theory. the theory is also that it should have dried by Sunday morning, but it didn't. so I dunno.
[ambrus]: I'll try today evening if it works now.
