water spillt! Starting problems. What should I do.

hello,

My macbook got water on it. I tried starting it once it was dry. It starts ans cut's off after 1 minute.

So I took it apart, but it seems like the motherboard never got water on it. All components seem clean and dry. I only had a issue with the keyboard staying blocked.

Once I put it all back together, I still had the same problem. Starting fine after 1 minute turning off.

I have a reset the SMC and PRAM. I have also done a apple hardware test. No results.

One more information, by deconnecting the track pad, the mac does not turn off.

What should I check, test? What is the next step?

thank you
