M1 Macbook Air Repair

It could be a number of things: failed power circuitry, failed screen, failed battery, failed power switch. There's no way any of us can diagnose the problem remotely. Without a stock of parts to try, attempting to correct the problem is likely to be an exercise in futility and possible in expense. Either take it to a third-party service provider and pay them for at least a diagnosis if not repair, or research one of the "fixit" type sites for additional steps to try and identify the problem. Or just give it up and recycle it. If it were me I'd opt for the last option.

Okay just curious why would you opt for the last option? Parts are fairly cheap and these don’t seem to hard to work on.

Most Mac parts are not very cheap these days.

As @varjak paw mentions, the hardware issue could be due to almost any part (or combination of parts) on this laptop. Troubleshooting the Apple USB-C Macs (2016+) is a nightmare even when you have known good spare parts available. Plus many of the parts on these 2018+ Macs are paired & calibrated for use on a single Logic Board/system. If you use parts from another machine (or even new parts) without calibrating & pairing them, then you may discover some things may not work correctly. Even the Lid Angle Sensor (yes a sensor) to detect whether the Display Clamshell is open or closed will only work with the original Logic Board, plus I think the sensor may be calibrated to the actual display (not entirely sure about the latter).

Good luck.

Because you could spend a lot of time and quite possibly a bunch of money trying to figure out which part is actually the problem (not all possible parts are cheap). Plus you quite possibly may end up just spinning your wheels since buying parts on line you never can be sure that they're good or even correct.

Up to you, of course. If you can find a source for parts that allows you return them if they don't fix the problem, then it's a somewhat different proposition.

Regards.
