Is there any support on this site??? Where are the DELL experts? Is there a better DELL support system?

Suspiciously quiet on this forum, where is everyone?

On the last point I see my post has been moved to the Win10 area from the XPS system page, and now I can see older posts. Strange.

Bump. Anyone awake there?

BTW hard to find this thread again, the listing page won't allow more than the original few posts to be shown - other such pages here don't seem to have that trouble. Hence the bump. Still have this problem, too expensive to just send the whole lot back to Dell because of a missing feature.

I went to Google and searched for, "Windows 10 no sleep option".
5th link down, open, "Fix: Sleep Option Missing in Windows 10 / 8 / 7 Power Menu"

* Click the Windows icon
* Type Power
* Click Power Options
* Click Choose what the power buttons do
* Click Change settings that are currently unavailable
* Check Sleep
* Click Save changes

Yes, of course I already found that panel and the 'sleep' settings was not there - hence my complaint. However I have now found the solution.

In the XPS8900 there are two HDMI connectors available, one on the machine case and the other on the video card itself. I've now obtained a suitable cable and voila! Using the direct connection to the video card (a GTX 750 Ti) I now have the sleep option! As well as that the NVidia control panel now opens, it didn't before. Others with this issue should  note that you need a HDMI to mini-HDMI cable, the standard HDMI plug won't fit. Even the mini one is a tight fit, so choose  one with a slim body.

It would be helpful if the documentation supplied with the XPS machine made this clear, I only found a pointer in another forum entirely, and that solution dealt with the missing NVidia control panel not the missing sleep option. Dell might also consider supplying a suitable cable with the monitor, HDMI is the emerging standard for this kind of connection.

Interesting. In most cases when there is an added discrete video card installed, the user should not connect a monitor to the onboard video out ports. I am surprised it let you boot up when connected to the onboard HDMI out port instead of the GTX 750 Ti. I would have thought that it would give you a pre-windows boot message. Unless you went into the BIOS and set it to Intel HD Graphics =
