Well, I had a bunch of coffee on my keyboard few days ago, I was quick to react but too late It seems, cleaned it, dry it at cold temperature with a fan. It does not start anymore, I am going to let it dry at ambiant temperature for now, and try to find a way to recover it from this bad stuff. Any ideas

Follow the teardown here, check the logic board for liquid damage and clean with 95%+ isopropyl if present Retina MacBook 2016 Teardown Try unplugging the trackpad ribbon and plugging in the charger after reconnecting the battery, it should boot automatically. Be careful, this model is more difficult to open than the older ones, so check the guide out first. If you are not comfortable with opening it, send it to someone who can check this out.
