Will not run on MagSafe power adapter if battery is installed
I have this MBP 15" Mid 2012 that someone spilled some water on. I have no idea how much because they removed the bottom cover and put it near a fan and then turned it on (against my advice, why do people do that?)
I blew it out with a compressor and it runs fine but when the battery is installed, it won't charge or run off the MagSafe adapter, it only runs off battery. If I remove the battery it will run off the MagSafe.
I have tried some resets, etc and even a new battery.
Is this a good question?
