Water Damaged MacBook not Charging?

Hi All,

Im going in for my second Question about my first Mac- a Macbook Pro early 2011. Thanks again to everybody that helped me find my replacement-now I am going back to fix the original water damage.

So here's the story;

I left my Mac on my desk next to my plants that I just watered. I unfortunately over-watered them and the water leaked under the mac while it was on sleep. It got underneath the computer and also got on my frayed charger. I came home after a few days to discover the water and immediately shut it off. Following this I discovered that fortunately my computer was still turning on and running fine but that the battery was no longer charging.

The Problems:

The Battery is getting lower and lower and when plugged in it says the following by the battery icon: "Battery Condition: Normal, Power Source: Adapter, Battery Not Charging". When plugged in I get a faint green light on the adapter.

The Things I have tried:

- Resetting the SMC

- Replacing the Battery

- Replacing the Charger

I was told by an authorized repair service advisor that If I remove the battery and then try plugging in/ operating the Mac with only the adapter then I could also rule out any problems with the MagSafe DC- in Board if it could operate fine. I tried this however, and it would not turn on.

My Question:

Given what that diagnostic showed me, is it possible that replacing the MagSafe DC- in Board could fix the problem? or from your infinite experience does this sound like a logic board problem? More generally, how can I fix this?

Thanks in advance for any help you guys have to offer!
