Hi, I have amost the same problem but my laptop is a Dell Inspiron N5110 with AMD. So I noticed that when I close the screen cover and open again, it back image screen requested to enter with my log in. It's like I had let the laptop hibernate.
The workaround was close the screen cover and open again. I still checking the bugs to see if has a upgrade ou update to fix it.
