I'm posting here as I got no reply in Lenovo forum:
I have Lenovo X220 with Windows 7. I set the power options to be turning off display after 10 min and going sleep after 15 min, but neither happens. After hour long I still have the screen savers images going on (seems forever). What's the problem? Been like this for a long time.

You could also setup a new user account, login with it and test.
