no worries! and that is even when you try some of the suggestions from https://unix.stackexchange.com/questions/609438/how-can-i-use-a-usb-keyboard-or-mouse-to-wake-from-suspend which I linked above?

Apologies, but what is RooibOS? I'm sure it's got nothing to do with tea ;-)

I don't know this topic very well, either. But here is a link to get you started. https://docs.armbian.com/User-Guide_Autoconfig/

Sorry for the confusion, friends Indeed, the Orange Pi 5 can go into suspend (sudo systemctl suspend) but at this point, the only way to resume it, is to press the physical power button on the Orange Pi 5 itself. No combination of keyboard presses or mouse clicks etc will ever wake it back up
