Hello,
I've enable on my laptop the black screen to suspend the screen after 5mn, I also have the brightness set lower, not 100% and I noticed when I come back to my desk, the brightness is 100%, I have to lower it again.
After a computer sleep mode, I don't have this problem when I turn it back on.
thank you
