Much to my surprise, the issue was resolved after a reinstall of the
system. I can't explain why, I don't think there was anything special
with my previous install. Maybe it's related to the fact that the BIOS
is upgraded in the meanwhile, I don't know...

Title:
  HP Zbook 14 G2: systems restart after shutdown

Status in linux package in Ubuntu:
  Triaged

Bug description:
  When I use the shutdown option in the menu or run "sudo poweroff" on my new Zbook 14 G2, the system shuts down and powers up again right after the restart. I have to push the power button again during startup to avoid it to restart. The system is more or less supported by Ubuntu* and the BIOS is up to date, so I thought this is worth a bug report...
  (I don't have a preinstalled system by HP, since I can't buy these here, this is an Ubunutu 15.04)
