Does this sound like Magsafe 2 dc in board failure?
My Macbook Pro Retina 15" early 2013, A1398 has no water damage and not been dropped. But the adapter had some non springy connector pins on the magsafe 2 head, with blackened outer two pins on the dc in connector. (I think outer two are ground, not power). Cleaned them up, found no metal debris in connector, magsafe head still hot and intermittent green and orange leds. Coconut battery showed good condition battery.
Jiggled magsafe 2 connector, smelt some burning, and leds now both out. Battery not charging but ran from power adapter if SMC reset. Laptop then worked as normal until battery got to below 5% or so, then nothing would power up computer.
Have got second spare working magsafe charger to check, but nothing can boot it up.
Does this sound like only damaged magsafe dc in board, or logic board probs? The laptop was working fine before it wouldn't boot up, but of course not charging battery.
Does the dc in board have any fuses or protection circuitry? Looking at photos of it, there seem to be some components on the small PCB, and someone mentioned a burnt out P7 (?) transistor on the board.
Any ideas?
Thanks
