Yes, exactly. It supports modern standby ONLY and that is the problem.

FYI: usually if s0 sleep is disabled the s3 will become available if supported by the bios. Not in this case because s0 is the only sleep mode that's available. So disabling it via registry will do nothing in terms of reenabling the s3. Bios by itself completely omits any settings to do with standby. 

The suggestion about removing peripherals is a complete nonsense and I hope you understand that. Who needs a computer that requires a user to disconnect everything every single time just to put it on standby? It might sound strange but most users who work behind desks have usb hubs, monitors, keyboards, mice and many other devices connected to their laptops. And they do this in order to do work.

Thanks for providing your device' details @stsh!

 

Upon checking, it turns out the Yoga 7-14ITL5 Laptop supports Modern standby out of the box, different to the classic S3 sleep mode. In modern standby, the CPU stays powered on as intended, so it’s not advised to be transporting the system in this state. I was trying to look in PSREF for the information, but its not stated in the official specs. It’s being stated in many reviews of the laptop and seems to be a common sleep-state for Intel 10^th Gen CPUs.

 

You can check the supported power states through the “powercfg /a” command in command prompt, but usually if the modern standby is supported, the classic sleep states aren’t. As we' been looking further into the modern standby option, it seems that some users were able to revert it back to S3 sleep mode through editing the registry, do take note that changing registries may pose risk so best to backup first before proceeding if you feel that it is an option for you.

 

You may also remove any peripherals that are also plugged to the machine before it goes to Sleep mode like USB flash drives, mouse or keyboard so that it will not disrupt the Yoga 7 itself when it Sleep mode.

I concur that this is problematic.

As a student who has to carry his laptop in his bag between classes, not having a mode that is intended to be used for transportation outside shutting down is a very bad experience. Especially since battery life is essential in my situation.

It would help me a lot if this was fixed as I am now forced to use my old machine for daily use on campus.
