Screensaver will not start on Lenovo b570

I am having an issue with my screensaver on my Lenovo b570 where the screensaver will not start. The screensaver never activates.

Searching around only shows results where the computer/monitor will not sleep either.

But this is not the case for me. The screen does indeed dim and/or turn off and the computer does sleep. Except the screensaver does not activate for me. My screensaver is set to activate after 5 minutes, except it does not.

The screensaver works when I hit 'preview' but it does not activate on its own.

Anybody know what the problem could be?

after three hours. Dim the display after 30 minutes, turn off display after one hour
