tried, not working
I have also tried replace "/sbin/init 0" to another command, not working too.
Every time I short pressing power button, then grace shutdown.
If I cannot fix this problem, I think I will take @JonathanM's suggestion, set boot immediately when there is power and disconnecting the power button header from the motherboard.
I will update the status to closed, if anyone need my DIAGNOSTICS please let me know. Thanks.
