People spill things. Sometimes on their notebook computers. If the spill is bad, it can result in loss of your laptop and/or data, and it could lead to hiring a data recovery service to get your data back (if it is important enough), and these services are not cheap. However, you can try some things after a spill:

(1) As quickly as possible after the spill, disconnect the battery from the notebook.
(2) Turn the PC over and skake out as much of the liquid as you can.
(3) Remove the optical drive and the keyboard (you might need to check the manual on this one). Once this is done, use a towel to dry out the insides of the PC as much as possible.
(4) Use a hair dryer to dry the insides as much as you can. Make sure you use the cool setting. Hot air can do more damage.
(5) Let the notebook sit for 24 hours to air dry. DO NOT turn the PC on at all until it is totally dry.
(6) Re-assemble the notebook and turn it on. If it works, copy off your important data, then see about arranging a professional cleaning. Otherwise, prepare for a repair bill.
