Answer to: MacBook won't switch on after swollen batteryI had the same issue before where I would hear the laptop turn on, battery is working, but no display.

I would try to checking the logic board carefully if corrosion is occurring (which could be brushed with a soft paint brush and 90% or above isopropyl alcohol) and if your laptop was soaked you might have to replace the battery.
