This was posted over in the Latitude 7400 touch pad erratic thread, but for anyone only watching the XPS one; Win 10 20H2 re-added the ability to force the S3 sleep, run this and after the reboot the machine will be back to the way it was on 1909... Anyone stuck on Win 10 2004 may not benefit from this workaround:
Edit: I'm going by what was reported in the reddit article; but the MS document is dated pre-20H2; so the 2004 version compatibility is subject to validation. fwiw.
I have this exact same issue on my 7390. I also have been chasing issues with the trackpad not functioning properly when resuming from sleep. The errors appear while the trackpad is not functioning properly.
Out of curiosity, are you running Windows 10 2004? I just formatted back to the factory image at support's request and found that the problem went away. I then noticed the factory image uses 1909. First thing I did when I got this laptop was fresh install 2004 from the media creation tool as I don't trust factory images.
Seems like this is more an issue with how the XPS drivers/hardware interact with Windows 10 2004.
Hi! Thank you for reaching out to us and we're deeply sorry about any issues that you might have encountered with your XPS system.
Feel free to upload a video a cloud based server like dropbox / google drive and share a public link with us through private message and we will be more than happy to review the behavior.
On my laptop xps 13 2in1 7390 service tag: Windows 10 (2004), after exiting sleep the touchpad does not work correctly, namely the delay when the finger touches the touchpad. Disabling and enabling the driver (Human Interface Devices) HID \ VEN_DLL & DEV_08B0 & Col02 helps In the windows error log of MTConfig Event 1 Help to deal with this problem. thank
I'm having the exact same issue on my XPS 13 2-in-1 7390 (Win 10 2004)! Trackpad lagging a lot after sleep and many MTConfig errors in event viewer. Very annoying as this makes the laptop hardly usable.
