I'm working on a Early 2015 Macbook Air A1466 that had very minor liquid damage to the keyboard 2 months ago. The keyboard was replaced and all seemed fine until it came back today and it wouldn't charge. Using genuine apple magsafe 60w charger it would react and shows the charge icon on the screen BUT the magsafe doesn't show any green or orange light at all and wouldn't actually charge the battery either. Then if you used a 85w charger it would show green then switch to orange and charge normally. Then every now and then the 60w would work and the 85w wouldn't. Everything else seems to work normally including all the ports, WiFi, display, etc... As mentioned the chargers we're using are genuine apple purchased chargers. Can you point me in the right direction on where to start looking?
