If there was just a little coffee it is possible the laptop is fine, I would try to re install windows, or use the built in restore function on your laptop. If the problem goes away your fine if not, well the coffee did do something. So you know if something like this happens again, turn the laptop off, remove the battery set it up side down if possible let dry for a few hours. My Sig other, split margarita on his laptop, We started with that. We had odd problems like the computer failing to boot, or the touch pad not working right. I took the thing apart and, took some q-tips and rubbing alcohol and cleaned every part that looked like it had Margarita on it. The laptop works just fine.
