[ubuntu] No support for device type: power_supply 16.04

Hi all
the battery on my brandnew laptop with Ubuntu 16.04 is not being detected.

After some researching in the internet I thought it was an acpi-issue and with a similar problem somebody had success in setting a grub boot parameter to acpi=force. But it didn't work with me.
When I type acpi in the terminal, then I get:
No support for device type: power_supply

But acpi is installed: #acpi -v gives me
acpi 1.7

Somewhere else a similar problem was called rather a problem of upower (https://bugs.launchpad.net/ubuntu/+s...r/+bug/1606159). But as far as I can see there was no solution offered. I have Upower client version 0.99.04

Has anybody an idea how to solve this? Any help is welcome!
Cheers
