I just spilt coffee on my laptop, what should I do?

Best bet would probably be to turn it off and stand it up on it's side (like a book). So that all the excess fluids come out. Also Remove the battery.

Leave it for at least a day and then inspect the keyboard and see if it's dried up.

Slightly more serious than my other answer.

The fact that it's a company laptop means that you should call the helpdesk (or whoever) and let them tell you what to do. Ignore the slight embarrassment you might feel, it's their laptop, you need to give them the chance to sort it out.

Chances are they'll be reasonable about the fact that accidents happen but if you do something that makes it worse they're likely to be more upset.

Reminds me slightly of one place I worked where a partner turned up one morning saying his laptop had just "stopped working" and he had no idea why. The helpdesk guys opened it up and dirty water started pouring out. At that point he admitted that carrying it home while drunk he'd fallen in a canal...
