MacBook Pro won't start / Tried everything
I'm kind of running out of solutions:
I have a second hand macbook pro (15", mid 2015), which looks brand new.
A few months ago, the battery stopped charging,I thought by then it was the adapter (a original apple one) and as I got a new mac from work, I ignored that and left it in a drawer.
As I'm about to quit my job, and I still need a computer, I bought a new charger from Apple and surprise, it stil doesn't charge.
I tried reseting SMC, PRAM, changed the battery and the magsafe adapter, but no luck so far.
When i press and hold the power button for 10 secs without the charger plugged in, and then plug it in, it will start, with fans fully on but goes into a boot loop (the bar goes up to a third).
I tried to boot it from a external ssd, but no luck, still going in loops....
When I tried to boot it in diagnostic mode, it will say that the battery is not detected....
Funny thing is that I can't even manage to start it with the new battery fitted in.
One more thing: when ever I plug the charger, no lights turns up, and the symbol of the battery charging is showing up whenever i press the on button.
Any one has got an idea?
I love this mac, and as said before it's still in good condition excepting that (...). I took everything apart, and nothing seems damaged on the boards...
Update (12/07/2022) ===
I finally received the new battery from Ifixit.
the mac is starting! That's for the good news... But the battery is not charging, just like before....
I'll start investigate.
Hi all, sorry I've been away for a while.
So.... I bought a new logic board, and still the same problem. I re-ordered a DC board as the seller was positive the logic board was tested and working, and guess what? That was it, everything is fine since then.
Thanks a lot to everyone who helped me here, if anyone has the same problem, just keep an eye on the DC board: from what I find out, it should be lighting up the charger when plugged to the logic board only, and everything disconnected. That could be helpful to find out the problem, once it is settled, you can plug back other stuff and keep on finding out what's going on :-)
