I have a new in box MacBook Air M1 2020 A2337 in my shop where the battery will not charge, Apple says it needs a new battery. Visual inspection shows no puffing or other irregularities on the battery. Is there a possibility to trick or bypass the BMS into trickle-charging the battery back to operational status without removing the speakers and battery?
Ist dies eine gute Frage?

It's a pretty easy for the USB-C ports on these models to get damaged. If the battery looks good I'd recommend removing the USB-C board and inspecting the pins on each port for signs of damage. You can see how to do that here.

I alway use. A USB-C power meter to measure the current load. Often I encountered power controller chip issues in the Intel systems. Here it’s a Texas Instruments CD3217B12 – USB and power delivery IC that could be the issue. Measuring the power at the USB-C port.
