On my recent build, S3 is available but S0 is apparently not supported by system firmware per powerfcfg /a. My GPU (RX 9070 XT) sometimes crashes upon resuming from sleep, so I can't use S3. This is likely a driver issue.

I'd like to try S0 if possible to conserve power when the PC is not being used. Anyway to turn this on in Windows 11? I heard all modern PC should support this feature and am not sure it's not supported on mine.

My mobo is Gigabyte Gaming X AX v2. Its manual has no language on S0/S3 sleep modes, except saying that Power LEDs will stay on in S0. This leads me to think the mobo does support it. Maybe there are some BIOS settings I need to change? 🤔
