Macbook Air 820-00165 shuts off when pressing power button once.

I have this logic board 820-00165 that was liquid damage. It was cleaned on sonic cleaner and replaced a few burned chips. Now it turns on and everything works fine but if the power button is pressed once the whole computer shuts off. Any ideas? Thanks in advance

SMC_RESET is triggered. Usually bad trackpad or flat cable, but crap around U5110 or crap under SMC also possible.
