shutdown goes poweroff

Greetings!

This is a leap-42.1 installation on a HP microserver gen8.
When shutting down , ether via CL with ‘shutdown now’ or via display-manager button (KDE-4.someting), the system right away powers off.
Shutdown scripts, e.g. /etc/init.d/halt.after, are not executed.

Any hints?

Thanks,
Wolf
