macOS not recognizing the battery
I've got a customers 2012 MacBook Pro which is not recognizing the battery.
So far I've tried as follows:
I've done everything on this Battery not detected, won't charge; strange connector on logic board? which is more or less
- SMC reset
- reset the PRAM
- disconnect the charger and battery and reconnect in varying different ways
I've also tried 4 different batteries, 3 different chargers and replaced the MagSafe board.
Everything has the same results. Not recognized.
When the computer is off the green LED on the charger continuously flickers on and off.
I read somewhere else that the charging IC may be bad, but I don't know how to test that.
Anybody have any other suggestions?
Is this a good question?
