Hybrid Sleep option missing in Windows 11 ("Hypervisor does not support this standby state")

I want to use Hybrid Sleep on a PC that I want to sleep when not in use to save electricity (drops from 330W on powerstrip to 30W according to Kill-a-Watt meter), but comes back fast (restore from sleep much faster than restore from Hibernate and Hibernate doesn't use noticeably less power, also hovers at around 30W on the powerstrip). We also have frequent power outages and want to be sure it won't lose anything if the power fails while it's asleep and no one's there to do a controlled shutdown before the UPS runs out. Hybrid Sleep is perfect for this, because it performs a full save to disk like Hibernate in case the power does go out, but only actually goes to sleep, not a full power-down like straight Hibernate, so it comes back right away in use.

In my Power Settings, I am missing the normal "Allow Hybrid Sleep" option:

Doing a powercfg /a, it says, "The hypervisor does not support this standby state."

So that's presumably the problem, but I'm not running Hyper-V on this PC, so Windows 11 must be using it for some process? I do have Windows Subsystem for Android installed, but it's not currently running (however, I do see a stub of VmmemWSA in Task Manager, so maybe that's the culprit, but not sure how to stop it, since WSA is not actually running and not set to always run). I'm not aware of anything else that could be using hypervisor unless Windows now uses that by default for security purposes (like sandboxing apps to their own VM invisibly in the background).

Any ideas? How can I get Hybrid Sleep back in Windows 11?

    Windows version is Windows 11, 22H2 (22621.1105)

    Of the 3 you suggested turning off, 1 is indeed on: Virtual Machine Platform. I believe I need that to be able to run install apps from the Amazon Android store, which I occasionally need. But even if none of them are running, Hybrid Sleep is still not available.

    That article you included about Windows 8 is a different issue. It may be related around hypervisor consequences (and its conclusion that you need to turn completely disable Hyper-V, not just stop it, is probably related to this problem), but that's about certain power states (Connected Standy is a very specific power state) being incompatible with Hyper-V. I'm not running Hyper-V, I don't use Connected Standby, and all the power states I need work fine. It's only the Hybrid Sleep combo (sleep + Hibernate) that is blocked.

    I know this isn't your fault or anything you can do about it, but this is a defect. If sleep is available (using any S-mode power state) and Hibernate is also available, as both are for me, then there should be no reason Hybrid Sleep can't work.

    Process is simple: Whenever the PC is going to go sleep, whether due to inactivity timeout or use request, first generate the Hibernate file and set the boot mode to restore from Hibernate, THEN put the computer sleep using whatever S-mode it supports instead of shutting it down. When it wakes from sleep, delete the Hibernate file and boot mode before returning control to the user. Very simple and no reason MS doesn't do this. Here's the full report of my options:

    Hello GraniteStateColin,

    Good to see you in Microsoft Community.

    Firstly, could you let me know the specific system version? You can check it by pressing the Win key + R key, and typing "winver", then press Enter, please take a screenshot/photo of it, and only send the relevant information without PII in the next reply.

    I looked up the information and found that your problem is indeed related to the hypervisor. Please make sure you did not enable the following features.

    1. Start > Settings, and then start Control Panel.
    2. In Control Panel, select Programs, and then click Programs and Features.
    3. In the left menu bar, select Turn Windows features on or off.
    4. Click to clear the Hyper-V, Virtual Machine Platform, Windows Hypervisor Platform check boxes.
    5. Click OK.

    Meanwhile, you may change/restore the default power plan. Win + Q to open the search box, type 'powercfg.cpl', press Enter to open the Power Options settings panel*, click "* Change plan settings" *to the right of the current power plan > "*Restore default settings to this plan (R) ", then click "Save changes".

    Additionally, I found a similar support page which may be helpful to you. It is published for Windows 8 Pro Windows 8.1 Pro, you may refer it.

    Connected Standby is not available when the Hyper-V role is enabled - Microsoft Support

    BTW, were these devices in a domain environment or did the devices works with the Hybrid Sleep option? If yes, you may contact its IT department to help you solve it, as each unit has its own unique security policy to secure the domain environment that‘s may be the root cause of the current problem.

    If anything is unclear, please do not hesitate to let me know.

    Best Regards,
