Hello, I'm having an issue repairing a 2009 Macbook Pro with water damage.
Half a bottle of Gatorade was spilled on the keyboard and the computer was turned off for roughly 1 year before attempting repair.
I disassembled the computer and took the main components (logic board, DC-In) and put them in an Isopropyl bath for ~ 2 days until it had entirely evaporated. I then reassembled and noticed the battery status would go from charging, to no battery detected over and over again. I took the computer apart again and noticed the Gatorade must have gotten into the battery because it was slightly swelling, and was sticky from residue. I removed it and bought a third party battery from Amazon. With the new battery installed, it's not detecting the battery at all.
I ran the coconut battery app and it's coming up all zeroes. As suggested on forums, etc, I reset SMC and PRAM(?) but that didn't seem to resolve the issue either. I'm wondering if I got a bad battery, or something is wrong with the DC-In component, or maybe there is a trace on the mobo that is shorted out. Just looking for a little guidance, I'm probably going to sell it for parts if logic board replacement is needed (~$240).
