PlatformAoAcOverride Removed after build 2004 Don't work any more.  yes there are issues being reported on XPS 9500 XPS 9700 Some inspiring models with sleep and Dell is working for a solution.  Undo any changes you have done to registry (extremely important)  Open CMD as admin  powercfg -a The output shows as network connected, that means Modern Connected standby is enabled.  run following these 2 commands   powercfg /setdcvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0 powercfg /setacvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0 In order to validate please run first command again and see if network shows disconnected.  Once again Dell is working on a solution but I am not a dell employee so don't know when it would be released. I have set all of my machines to Hibernate after 20 minute after sleep. The issue only happens when machine is in sleep for a long time.   
So per the title, since Microsoft removed the CsEnabled key hack and Modern Standby overly restricts my power plans, I was trying to use the PlatformAoAcOverride.  That did restore my ability to control my plans and things seemed great until I tried waking the laptop.  It simply won't wake.  I have to hard power off.  Delete the key and sleep/wake work again, but no real power plan control.   I did see some reports of 9700 devices being able to wake after similar challenges by disabling some things like SMM and Absolute in the BIOS, but that hasn't helped here.  Anyone solve this problem yet, or know of a way to use Powershell or something to restore my power plan options if I leave Modern Standby enabled?
Cannot wake my XPS 9500 if I use the PlatformAoAcOverride key to disable Modern 
Standby. Anyone have success?
