Press the button on the postion of PWR_BTN and GND.the ubuntu Pop up selection box button(Lock,Suspend,Restart,Shutdown).We do not select anay one,Keep no operation.

hello qitb,

that’s it. you’re using different JetPack release.
is there any special use-case to enable/keep power selection menu there?
thanks

No Special use case.We test,find the differ.
Make sure the reason is JetPack Version?

thanks.

hello qitb,

it’s JetPack-4.5 (and later release) to auto shutdown the board after enable power selection menu and keeps for 20sec.
