UM790 Pro - sleeping

[Vic Lovan]

I'm looking for help on the UM790 Pro. I'm pretty experienced with Windows and many computer hardware settings, I work as sysadmin/desktop support, but this one has me beaten so far.

I can't seem to make it NOT sleep for the network connection. I've changed the power settings for Windows to never sleep. I use RemotePC and DWService to remote into computers including mine. RemotePC even has a setting not to allow the computer to sleep. I've turned off the hardware settings in Windows for the power management for everything I can find, network NICs and USB. I've installed Power Toys and used the Awake feature. I looked at the BIOS settings, and nothing seems to keep it online.

I'll try to keep an eye on this post for any suggestions, and thank you in advance.

It seems like there's something hidden in the registry or elsewhere that still allows it to sleep. Windows is a pita sometimes. I've disabled all of the same stuff on my laptop and if I kill off processes and let it sit idle it will go to sleep. If I leave something running that boosts the CPU or GPU up from idle it will stay on.

Conversely on my Linux box it doesn't sleep ever.

if you only have a balanced power profile, it’s because your system is running S0 modern standby.
you can check from powershell or CMD
> powercfg /a

to fix, add this DWORD key called "PlatformAoAcOverride" which will automatically be set a value of "O" here
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power" , then restart your computer; this essentially forces your system to use a more traditional sleep mode (S3) instead of Modern Standby, which is a pain in the butt on these minisforum PCs running Windows 11 as there is no BIOS option to disable S0 Modern Standby.
