[[Electronics Water Damage]]
Great guide on what to do, follow that guide.
But if your laptop gets wet, Dont try to keep using it. Even if it was the cover like you said, still open it and clean it.
If it was water, drying would help, but it was an energy drink, which are LOADED with sugar and sugar can leave a conductive residue on the board causing shorts.
If that doesnt work after cleaning the entire laptop, its probably dead and there is nothing really you can do. Your data will probably be fine and you can get it back, but the rest of the laptop is dead.
Also if it does work and you still get the no battery detected, the battery is probably dead and you just need to go and buy a new one.
