XPS 8930, Sleep/Hibernate Fail

computer worked fine since purchase a year ago or so.  As stated, all settings are at default (although I've tried others).  Allow Hybrid Sleep is enabled (as suggested somewhere else).  Trouble started about a week or so ago.  

ms-settings:powersleep  Sends me to the same dialog as settings/power&sleep/additional power settings.  been there, done that.

When I press the power button to Sleep, When I press the sleep button,
Click on Save changes.  ???  I don't want (and never have) used the power button to engage sleep mode.  I always use the start button to access shutdown with the choices being sleep/hibernate/restart/shutdown.

MS has installed Security Intelligence Updates for MS Defender on the following dates.

6/30  7/1  7/3 (3)  7/4   7/5   7/6 (3)

They've been busy.

What model Dell computer do you have? What OS and OS version are you running?

XPS 8930  64 bit system  WIN10  1909

Just to repeat.  This XPS 8930 has been working great ever since purchase (more than a year ago).  Only within the last 2 weeks or so has the problem arisen.  Evidently others have been having this problem.  Non Dell suggestions such as disabling fast startup and wake timers have been tried. 

It has been suggested that besides the network adapter, some piece of hardware is waking the machine.  Suggestion is to use CMD to identify hardware possibilities.

powercfg -devicequery wake_armed

 I will try later.

In the BIOS, disable "Intel Ready Mode Technology"

In Windows, uninstall the "Intel Ready Mode Technology" App.

Yes, you can then reset/fix Power-Profile with proper powercfg commands .

After browsing the Web, the following seems of interest.  Although my problem hasn't been listed, many are reporting problems with Win 10 version 1909 and Update KB4535996.  In my case, I have not had not problems when 1909 was installed and I do not have KB4535996 installed.  

Intel Ready Mode Technology description  --   It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The software installer includes 28 files and is usually about 6.3 MB (6,602,752 bytes). isctsoftwareupdate.dll is the automatic update component of the software designed to download and apply new updates should new versions be released.

This isn't something that I'm willing to eliminate.  I'm especially not willing to play with the BIOS.  At the present time, the sleep/hibernate/power off functions all restart the computer.  My computer shows that Win 10 Version 2004 is not available now, but will be coming soon.  So I'll live without the Windows power options and see what happens with MS.

Started Windows and got a message that Windows did not load.  Notice gave me options.  Two of which were choices of uninstall quality update or uninstall feature update.  Not knowing the difference, I choose feature.  This update failed so I tried the quality uninstall which completed.  Not sure what exactly was uninstalled.  No change in clearing my power problem.  Shortly after, Windows automatically downloaded cumulative update for 1909  2020-06.  No change.

Based on previous identification of possible interrupters, I did a WAG and disabled the Killer E2400 Ethernet controller.  So far this action has stopped the power up action in sleep mode.  Before the power up would happen in 2 – 3 minutes, Now after 2 hours, no power up.  Will continue to monitor and see what happens.  

Still working.  Bad Killer!

Hi @cyberanvil, I have the same problem and today is the 4th day contacting the support assist. I don't think they have a solution. They asked me to hard reset, disabling my hibernate mode and update and scan the system with support assist without a conclusion. How about yours now? is it already better? I follow the solution to disable the killer something, but the problem persists, maybe I need to disable all of the adapter in that options. 

Been awhile.  I went to the listed Killer Networking site and downloaded what was supposed to be a fix.  Still seems to be working.

Just to add, by disabling all Killer adapter functions, my problem was solved.  But then I could only connect computer using Blue Tooth.  Not what I wanted and so I used the link as I provided and everything is working fine.

Greetings,

Just for the benefit of people new to this problem.

The solution I found was to open killer ethernet device properties in device manager and disable allow this device to wake the computer in power management tab.

So no need to disable the killer ethernet adapter.
