9570 XPS 15 Power Button Options "Turn off Display"

Jphughan, 

Thanks for a quick reply. 

I did not install any additional software, as it was always a Windows option.

Here is a guide now how to do it without any addons:  https://www.addictivetips.com/windows-tips/power-button-to-turn-off-the-display-windows-10/

This is what it looks like under power options. The 9570 is identical, minus the turn off the display option. 

Now, I understand you may not have experienced / used it before, but it was a very useful function to me (saving power without having to lock / close the display or have to sign in afterwards) 

Any input would be greatly appreciated.

I grant that I haven’t seen everything, but in 15 years of working in IT, I personally have never seen “Turn off the display” listed as a Power button action on any PC running any version of Windows. In fact I even own the XPS 15 9530, which is the sister system of the M3800, and that option isn’t there (also running Win10 Pro) — so maybe you previously had it due to some third-party app? There’s a seprate setting for turning off the display based on time, and on newer versions of Windows, the display will turn off about a minute after you lock your workstation, which you can do by pressing WinKey+L. Closing the lid will also turn off the display if you have the lid close action set to “Do nothing”.

I don't know about using "advanced options" to get there, but:

Right click the Battery icon in the notification area, select Power Options
Or
Open Control Panel (select Small icons if not set), select Power Options
Or
Windows Key+R powercfg.cpl

"Choose what the power buttons do" -- "Turn off the display" should be listed in four of the drop downs. It is not an option for "When I close the lid", because the display automatically goes off when you close the lid.

Thanks for your reply. 

As per my initial question, the "Turn off the Display" option is not listed. Which is what prompted me to create this thread to begin with. I'm just curious if it's a Dell issue, or a Windows issue. 

How I access the power settings does not seem to be relevant, as the option is missing regardless of how I access the drop-down (I tried W+R, but since it ultimately brings you to the same page, it gives the same options).

As you can see below, the "Turn off the Display" is not available in the dropdown.

Any help would be greatly appreciated.

I think you may have answered my question! 

Modern standby would explain all of the issues I'm having (laptop wakes up when AC is connected or disconnected), no screen off option, etc.

I'll have to do further research into how to disable it, as I don't want my laptop to act like a phone / tablet.

I have a 9365, and my configuration DOES have the option to turn off the display. The fact that yours does not says it is probably a configuration setting somewhere, or a difference in BIOS or driver versions.

thanks evinod, this is perfect.
