Open Device Manager and double-click the Killer Ethernet entry.  Click its Power Management tab and make sure the box "Allow this device to wake PC" is not checked. Now click the Advanced tab and scroll down in Properties box and set "Wake on Magic Packet" to disabled. and then scroll down further and set "Wake on Pattern Match" to disabled. Click OK to save the changes and exit Device Manager, and reboot. Does that help? If that doesn't fix it, click Start>Run and type in services.msc and press OK. When services.msc opens, disable all Killer services that are listed. You don't need them. Then close service.msc and reboot. Does that help? BTW: Why are there so many Netwtw10 entries in your log? That's a WiFi driver. So you might want to double-check that it's not allowed to wake the PC on its Power Management tab in Device Manager, or just disable the WiFi card in Device Manager if you don't use it. You can always re-enable it if you want...
I have an XPS 8940 SE, with the 10900K CPU. I'm having issues where it will not stay in sleep mode and am wondering if anyone else is having the same issue. Per the system event logs, it appears to be the Ethernet controller that keeps waking up the PC, yet there is nothing that should be doing "wake on lan", nor can I find a way to disable it.If I manually put it to sleep, it generally wakes back up in 1-30 seconds. If I let it go to sleep on its own, it may or may not stay there awhile. Once I observed it sleep for several hours, but on the other hand, one it woke up in the middle of the night and didn't go back to sleep for over 36 hours.
