hello, i have a water damaged macbook a1278 after i did a isopropyl bath and let it dry thoroughly i get the green light when i plug in the charger but it does not start, not even if i do a keyboard bypass. If i connect the battery though, the laptop powers up by itself and the fan goes in full speed, displaying nothing on the screen. i don't get any sounds either. In orded to turn it off i need to take out the battery.
Any ideas?
many thanks
