When it comes to liquid contact, the most important thing is to cut power as soon as possible. The longer the device has electricity running through it, the higher chance of a short circuit and the more damage will be done. First, shut the laptop down and unplug it immediately. Using [guide|12347|this guide], disassemble the device and remove the logic board and other major components. Wipe them down/immerse them with 90%+ isopropyl (rubbing) alcohol.

Then, let us know the results when you are at this point and we can troubleshoot any possible part failures and what can be done in terms of repair.
