A big thank you, nicoar10.

Hello R_J,

Thank you very much for this valuable information.

It helps me a lot to know that the second component is actually a 150uF 6.3V JE8 capacitor and not an inductor or diode. This completely changes how I need to approach the replacement.

I will wait to see if anyone else can share the exact schematic part numbers or references for this area, but your breakdown gives me exactly what I need to start looking for the right components.

Thanks again for taking the time to help me out and for finding that image....

Hello everyone,

I am troubleshooting a MacBook Air M1 Model A2337, Logic Board 820-02016 that suddenly went completely dead with no signs of life, no trackpad click, no display.

Here is what I have done and found so far.

Initial testing involved trying a soft reset and testing different USB-C chargers including a 75W PC charger, but the board pulled no current and remained unresponsive.

Battery isolation was the next step. I opened the Mac and disconnected the battery connector. Testing on wall power yielded the same result, it was totally dead....
