My computer doesn't go to sleep.
My monitor turn off as i want but the pc not rather, i notice that power consumption pass from 24W to 27-30W.
Therefore i use Windows Performance analyzer and i find that after 100s, the process "logonUI.exe" start and use 2/3% of my cpu.

I have no idea how to solve this problem. It's very frustrating!
Anyone has a solution?
