Bad battery? Bad logic board repair?

I spilled powerade on my laptop, so I sent my laptop for logic board repair, replaced the keyboard and battery indicator. Received the laptop and functions works like normal than about a month later, will not boot up anymore.

When plugged into the charger, it shows green and full charge when the indicator is pressed. When not plugged into the charger, pressing the battery indicator shows nothing.

What should I do? Should I try to clean everything with alcohol 91%? If it is battery problem, the laptop should boot when remove battery right?

Attempted to SMC, nothing happened. Press shift+control+option+power, release, and press power, nothing.
