So recently my A2159 MBP fell asleep and froze when I tried to wake it up. I then hard reset it and it has yet to ever boot up again. I’ve opened it up and noticed that holding the power button got one little spin of the fan and stopped. I disconnected the daughter battery cable and then the fan spins without stopping, although I’m still not booting up at all. Any ideas?

Your systems logic board has a problem! Do you have an AppleCare+ service contract? You’ll either need to find someone who has the skills to fix your logic board (if it can be fixed) or just replace it.
