It being on at the time and trying to power it on immediately are the 2 fails. Otherwise if you opened it up and cleaned it all with 99% alcohol then I don't see it dying. It's possible it's just shorting out and if you open it up and clean it perfectly it will work again. I wouldn't wait for it to dry or whatever. If it was water then maybe it would all evaporate but coffee might leave a gunk residue that could carry electricity for a long time. Plus if she used creamer it's going to smell like a butthole.
