Windows 10: No S3 standby available though supported by PC

Hi,there is no S3 standby available on my Windows 11 machine, even when freshly reinstalled. Modern Standby S0 is used, but when disabled with the registry value then there is no sleep option at all.My Mini-PC definitely supports the S3 state I need the low power consumption because:1. sometimes, after some minutes in modern standby, the pc goes to S3 and2. using "suspend" on a portable usb linux distribution puts the pc to S3 directly.In BIOS there is no particular setting for S3 but some settings are available like "ACPI C1 declaration", "ACPI CST / PSS" and I tried to change the TDP and

How to enable S3 Sleep State and Disable Modern Standby (S0)

Thanks for the feedback, the powercfg command is returning the following information "The system firmware does not support this standby state", more modern Intel processors no longer support S3 mode.

The ideal now would be for you to check with your PC manufacturer's support if there is the possibility of supporting S3 mode via a BIOS update.

 

PC won't wake from S3 Sleep after Win 10 upgrade


This was working fine on Win 8.1, but since my upgrade my PC now won't wake up from any keyboard, mouse or PC power button press once in S3 sleep or hibernation.

The only way to wake the PC is to reach back to the PSU and turn the power off, wait 5 seconds, then turn the power back on. I can then press the power button on the front of the PC and Windows then resumes from sleep.

powercfg /A returns this:

The following sleep states are available on this system:
Standby (S3)
Hibernate
Hybrid Sleep
Fast Startup


The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.


Standby (S2)
The system firmware does not support this standby state.


Standby (S0 Low Power Idle)
The system firmware does not support this standby state.

I have the latest firmware on my relatively new Gigabyte 970A-D3P. Any ideas?

 

sleep problem with standby when both s1 and s3 shows under powercfg

My supermicro X9SRA board only have the option diable, s1, s3 under acpi.... but if i select s3 then under windows powercfg /a it would give standby (s1 s3)

and that seems to be the problem that i can't properly wake the computer after it goes to sleep and power down everything. a touch of the keyboard would wake up the fan but you just have a blank screen and an unresponsive computer...

conversely, i notice a few other computers i have where s3 sleep works properly, under powercfg /a, you only have standby (s3)

is there a way to tell windows to specifically only use s3 when both s1 and s3 standby are listed under powercfg /a ?
