Title: MacBook Air M1 (2020) top USB-C port won't charge
My problem:
I have a MacBook Air M1 (2020). My bottom USB-C port charges my MacBook, but my top port won't charge consistently.
Steps to reproduce the issue:1.
Plug my charger into the bottom USB-C port. It charges normally.
2. Unplug the charger and plug it into the top USB-C port.
3. The charging symbol doesn't appear, and my MacBook doesn't seem to charge.
How long have you waited for it to start to charge. I have noticed that sometimes on Mac laptops if the charging cable is disconnected and then quickly reconnected, either to the same port or a different port, the charging symbol (looks like a lightning bolt) may not appear for some seconds, sometimes up to 30 or 60 seconds. This might be a built in delay to protect some circuitry. Have you waited for a solid 60 seconds for it to start charging. This behavior might be different for different ports.
My battery health says “Service Recommended,” with 79% maximum capacity and 563 cycles.
As John Galt noted, if your battery shows service recommended you should take it in for service. The fact that the battery is faulty makes this harder to diagnose or understand. The two ports do have different circuitry so a marginal battery might barely work on one port but not work consistently on the other. I think you have to address the battery first.
My question: Is there anything else I can try at home to fix the top USB-C charging port without taking my MacBook in for repair?
I don't think so. All you can do is shut down, restart, reboot, the equivalent of reset SMC (which you have done), and do things like reinstall the operating stysem, which won't help here.
I second the other advisors who said ... take it in for battery service. After the working battery is in, then you may find the ports both work. If one doesn't work still, that will be a second service to do.
