Good morning from germany! ;-)

Just a question about the power button at the SATA HAT: how does it work? Is it like a hard shut off?

I guess, if i want to power down the NanoPi M4 there are some things to do: close processes, clean write cache and so on - a regular shut down will take some time before powering off.

I've already tried to read the logs but there are no entries about the shut down.

Any hints?
