Chosen Solution
So I have a dead mbp. New battery coming Friday. Just bought a new ac charger. Tried the pram and smc resets…nothing. Tried with and without old battery doing all of the above. I’m assuming it’s a bad logic board but I’ll come to that conclusion when new battery gets here. My question is that there must be a way to actually fix/revive the logic board. Perhaps some soldering involved. Is this possible? If so how can I find these tiny parts?
@somexdude like @e_ah said change the battery first then re-evaluate. This could be a bad MagSafe as well as dirty pins on it or a bad Magsafe DC-in board. Use these guides MacBook Pro 13" Unibody Mid 2012 Repair to work on it.
Well, you’ve covered all the bases. For additional info, check out this thread… Not charging, blinking green/orange light Best wishes…
