New t480s Power Manager won't turn off display or go to sleep

I have a new t480s, bought last month. The power management does not turn off the screen/display after the specified amount of time. Also the laptop doesn't go to sleep after the specified time either. 


I've already tried updating Lenovo PM to the latest version.


Is there anything else I can do or is this a known issue? 


Thank you!
