Where was the liquid spill?

I think you can close this topic.
After re assembly everything together, The mbp is turning ON and stays ON with the battery, tested from 28% to 25% during around 10 minutes.

Strange because, the board was just resting during 2 months........sometimes Do NOT Rush.

Thanks
