The first thing to do now is reset the SMC and PRAM, and see if it helps:
-
To reset the PRAM, press command, option P and R
-
-
To reset the SMC, follow this, I pulled it right off of apple's support pages
+
* Hold option, Command, P and R for 25-30 seconds
+
For the PRAM, refer to the following steps:
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
-
Shut down the computer.
-
-
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
-
-
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
-
-
Release all the keys and the power button at the same time.
-
-
Press the power button to turn on the computer.
-
-
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
-
-
I suggest replacing the batteries ASAP if you fix these laptops doing this, the batteries may have shorted out and it's more dangerous then a exploding LI-ON battery, and these are LI-PO, these go off, you are in trouble!

Trying new DC-IN boards may help, the other part that can take a pretty nasty hit from water is the logicboard, so if different DC-IN boards fail, look to the logicboards going bad

If neither helps, board level repair is required, or a new DC-In board (likely both). I would also replace the batteries ASAP if you fix the laptop since it will likely fail prematurely.
