Hello, i have a batch of 10 Macbook Pros A2179 bought from a Costco return wholesaler.
The 10 of them show the exact same behavior;
They auto power on, to internet recovery spinning globe, fans to 100%.
Power consumption on USB-C port is 0.43a, shuts down as soon as unplugged. Battery doesn't charge at all. However, it boots to 20V on the Ampmeter.
Based on their iBridge versions (4.x and 5.x) these were shelfed for a long time.
All of them power on the same way; 100% fans, shut down as soon as they are unplugged. Removing... -

Hi everyone,
I have a MacBook Air A2179 in my hands that had power problems (5V to the USB-C port intermittently).
After a first inspection I could see that the D3302 protection IC was burnt out, so I replaced it but the problem was not solved, it seems like intermittent 5v input.
I then replaced the two u3200s (CD3217B12ACE) and now I have stable 20 volts and the macbook has turned back on.
Unfortunately I have a further problem, it works very slowly and the fan runs at maximum and if I disconnect the charger it turns off, it's as if the battery was disconnected.
