XPS 8920 won't wake up from sleep by touching keyboard or trackball

You said to go into the bios>power options>advanced>enable usb wake. I did all that and it started waking by touching any key or mouse BUT now that only works for an hour or so and it goes back into the no waking problem. (It only works well for an hour).

You're missing my whole point... !

READ THIS THREAD!   en.community.dell.com/.../20025253

I posted a very LONG list of other things to try in that thread when enabling USB Wake Support in BIOS didn't fix this problem for richard1939.

If you don't want to try those other things, then I give up because I won't be able to help you.

I did everything you originally suggested and it works now but only for an hour.

I did everything you suggested and it's still not waking after an hour by tapping a key.

What about moving the mouse?

Where are mouse and keyboard connected? To rear USB2 ports or somewhere else? Try connecting to different rear USB2 or USB3 ports.

I'll ping my Dell tech contact...

Tried the mouse many times. Tried different usb ports.

A quick Google shows that many different PC models/brands are experiencing USB Wake issues after updating to Win 10 Fall Creators Build 1709, eg:

So at this point, I don't think there's anything else to do until MacroStupid fixes their latest mess. I guess you could set Sleep to Never, and set hard drive and monitor to turn off after some fixed interval. At least that should save some energy...

It's all fixed, I disabled hibernation sleep.

Thanks RoHe--followed your advice and my new XPS wakes with a simple key stroke.  Happy New Year

I am having this problem too on my xps8920. I have updated the bios and set the appropriate wake flag, updated all of the intel drivers from the intel website because dell lags behind in these. I have set all the appropriate checkboxes in the windows power management app to allow usb devices to wake the pc. None of these things have stopped the problem. This is very, very inconvenient and costly in terms of power consumption and lost productivity when things that take time, like bulk copying and video rendering, are in progress.

dholeman1 -  Did you disable Hibernation in the active Power Plan?

I guess you could set Sleep and Hibernation to "never" and just set the power plan to turn off the monitor and hard drive after a certain period of inactivity, at least for now...

And you have to be careful about downloading drivers directly from Intel. Dell sometimes tweaks drivers for their specific hardware and native Intel drivers may -or not- work correctly.
