[ubuntu_mate] no power management in 16.04 and no shutdown

Hello
I have Ubuntu Mate installed on a new laptop. It is the only OS.
The system always freezes when I shut it down - except when I reboot! So I figure that the issue is about something that sets reboot and power off apart.
At the same time I notice that the system doesn't recognize the battery. It always claims that there is none - even when ruing from the battery. Maybe the two things belong together that a broken power-management hinders a proper shut down?
The system uses upower. Or letś say it is supposed to do so, because when I check, I get this:
#upower -i /org/freedesktop/UPower/devices/battery_BAT0
native-path: (null)
power supply: no
updated: Do 01 Jan 1970 01:00:00 CET (1470386643 seconds ago)
has history: no
has statistics: no
unknown
waing-level: unknown

Then I checked acpi and I got numerous error notifications:

Being a newbie in Linux I don't really understand anything. But it doesn't look good.
What can I do? Any Ideas?
