Macbook M1 - unable to load diagnostic mode - power button not working

Hello there,

I have a Macbook Pro M1 (Late 2021), using Sonoma MacOS. Im trying to get into diagnostic mode.

After shutting down, I tried to hold power button for a long time, but it would go straight to the login page, not getting into startup loading option.

I believe the power button is not working properly. Is there a alternative way to access diagnostic mode?

MacBook Pro 14″, macOS 14.4

M1 Mac with flickering touchbar, stuck in progress bar after entering PIN, then resulting in bootloop My 2020 M1 Mac touchbar is flickering, it doesn't show the usual menu and after entering a PIN to log in, it stuck in the progress bar and then it restarts. Occasionally after it restarts, the touchbar runs normally, but often time it's off. After an examination using Etrecheck, it says there is a kernel panic. I am not familiar with tech like this, could someone explain this and is there a solution to this case? Hopefully, I don't have to replace my Mac as I am just about to start my new semester in college. Thanks!
