Don't drink and geek !
My friend's Mac wouldn't start up since a full bottle of Tequila was spilt on it.
First I had to clean the casing and motherboard with alcohol and coton swabs. I thought the HDD was dead so I tried another one but I couldn't see it in the disk management (I booted from a USB key I made with 10.9 installation). At that point it could only be the cable or the controller. The cable is easier to replace so I gave it a shot and fortunately, I was right. I put the original HDD back and it work fine now (still a bit sticky though)
Don't give up on your MBP, if it can survive the party apocalypse, I will survive much more !
