Rather than (both literally and figuratively) lose sleep over Modern Standby, I suggest that you try to disable Modern Standby. This can be done in the registry, at least if the UEFI BIOS can support the ability to disable MS (disable Modern Standby, that is... )
So if you run the following command from an elevated command prompt:
Then if you reboot next, you can run theCode:reg add HKLM\System\CurrentControlSet\Control\Power /f /v PlatformAoAcOverride /t REG_DWORD /d 0powercfg a
again (orpowercfg -a
orpowercfg /a
) to see if S3 Standby (aka Legacy Standby) is supported now. If yes, then you should now be able to see the Power tab in Device Manager again, where you should be able to use the good-old familiar "Allow this device to wake the computer from sleep" checkbox etc.. If no, then you need to shoot @ Dell.
If you want to undo the above mentioned registry change, run this:
...from an elevated command promt (and reboot again after that).Code:reg delete HKLM\System\CurrentControlSet\Control\Power /f /v PlatformAoAcOverride
