Water damage repair - laptop won't run on battery
Hello Everyone -
My brother and I are looking at his MBP which was very slightly water damaged, he said literally a couple drops of water. It had the issue with the fan running constantly and very slow, and there was an SMC code PFM006 on the apple hardware test as well as a PPN001 "there may be an issue with the power management system".
I removed the logic board and cleaned all the areas I could see with water damage, green corrosion marks. A few of the connectors had a bit. Amazingly, the PFM006 and PPN001 are all gone and the computer runs perfectly, only on the power adapter though. The battery is detected, only 250 charge cycles and it says 'normal' condition. But when we unplug the magsafe it still shuts off. I have tried cleaning the connections near the battery connector but I'm confused because I'd think that if the computer will detect the battery and give voltage information/charge cycles, etc, that it should be fine.
Any ideas on what we can look at next would be appreciated. I'm trying to narrow it down between an actual battery issue vs a logic board one.
