MacBook only powers on with adaptor, doesn't detect new or old battery
So I've been fixing a macbook I got cheap on gumtree that was being sold as faulty. I needed to replace the HDD, fan,LCD and the keyboard and it turns on and everthing works fine except for the battery.
So here's what I've learned from troubleshooting so far
- Only turns on and stays on only when plugged in
- Doesn't detect original battery or new battery
- Tried resetting PRAM, SMC
Any information would be helpful
