After turn off "display spleep" it Power Management the screen continue to slow go dark after some minutes of inactivity. How/where to turn off this?
On AC Power (I never use it on batery), the options and values are currently:
Put computer to sleep when inactive for: Never
When laptop lid is closed: Do nothing
Splin down hard disks when possible: unmarked
Put display to sleep when inactive for: Never
And it still is turning off the screen light after about 5 seconds..
