Hi there, I've got a Macbook Pro A1278 board code 820-2936-B in which I have a very strange charging issue.
Backstory is when I plugged the charger in, it would give a green light and swap to orange like normal but after a few seconds would go off to no light, laptop still powered on and functioned fine.
So naturally I replaced the ISL chip first which made no difference so I also removed and reballed the SMC. This seemed to fix the issue for about an hour until I was back to square one again.
Decided to then take an SMC from another board, reball that and give that go. This time it was fine again but after 2 or 3 hours the same issue re-appeared.
Has anyone had this issue before or has any idea why the issue seems to be fine for a while after a reball but then proceed to revert back to the original issue?
Have also tried a brand new charger which made no difference.
