I bought a second-hand 12" MacBook and was disappointed to discover it doesn't charge. I'm expecting to return it, but I'm frustrated that I can't fix it.
The battery is showing at 35 cycles but not holding any charge whatsoever. I presume it's been sat on a shelf for some period of time and has drained, but I can't imagine that it's actually dead at only 35 cycles.
I've reinstalled macOS, run an SMC reset, and reset NVRAM too. I've tried another charger for the same model.
Unplugging instantly powers down and it shows no interest in charging at all. I think it's got to be returned at this point. This is frustrating as it was a present for my wife's birthday this weekend, so I've been trying to fix it. Is there anything else I could try?
