macbook pro won't shut down when power supply plugged in

Any ideas why my MBP M1 Max won't shut down when plugged into the power supply? I can shut down, computer shuts down, but then it boots back up right away. When I unplug the power supply, it stays shut down.

MacBook Pro (M1, 2020)

Any devices attached to the computer when shut down and plugged into power?


Is it related to the auto-boot feature, which starts your computer when lid is open or plugged into power. You can disable this feature by going to Utilities > Terminal. Copy the command below and hit return:

sudo nvram auto-boot=false


This can be set back to normal by changing the value to true.
