I've had this computer for about a month. Dell XPS 8930, i7-8700, win 10. In the past few weeks (I can't seem to pinpoint to an update). When I attempt changes it simply resets itself to sleep 1 minute. It will be okay for one or two boots but then resets itself. I have set power settings to never, I tried the changing the setting with registry edits several times including turning off the sleep button function. I've reset to defaults. Most recently even turning off hibernation. I'm a bit baffled. Thanks in advance for your help.
