No Sleep option - Standby (S3) The current Device Guard configuration has disabled this standby state.

Question

No Sleep option - Standby (S3) The current Device Guard configuration has disabled this standby state.

JD 51

Here we have a ThinkPad laptop running Windows 10 Enterprise in a domain environment. The Sleep option is missing both from the power menu and is not shown even in the control panel power options.

Running powercfg /availablesleepstates gives:

Standby (S3)
    The current Device Guard configuration has disabled this standby state.

I have googled this sentence but there is not a single reference or mention.

Core isolation is not enabled on this laptop. Device Guard support in BIOS is set to Disabled, and no group policy is set about configuring this feature.

Any idea on how the S3 sleep option can be re-enabled is greatly appreciated. Thank you!

I had this same issue on a Thinkpad L15. The solution is to disable "Windows Defender System Guard". Note this is a separate and independent of the "Core isolation" feature, even though it's categorized under it in the Windows Security applet.

From Start Menu type "Windows Security" and launch the app it suggests

Click on "Device security"

Click on "Core isolation details"

Turn off "Firmware protection", which is described as "Microsoft Defender System Guard"

Reboot your computer

The Sleep option will now be shown in the power options in the Start Menu.

Thanks. So may click-bait articles on the web suggesting the same old options (eg, gpedit or regedit chnages) that didn't come close and this solved it immediately. Was pulling my hair out and you helped me avoid a full re-install.

Run "powercfg /a" at an admin command line.
Confirm whether your system firmware support Standby (S3).

Open Group policy editor:

Computer Configuration -> Administrative Templates -> Windows Components -> File Explorer
Enable Show sleep in the power option menu

Computer Configuration -> Administrative Templates -> System -> Power Management -> Sleep Settings
Enable Allow standby states (S1-S3) when sleeping (plugged in)
Enable Allow standby states (S1-S3) when sleeping (on battery)

Hi,

Thanks for the info. Unfortunately, all configurations have been set to enabled, while the problem stays the same.

I think the group policy entries you mentioned only apply when some of them are disabled. However, the status that powercfg /a gives (The current Device Guard configuration has disabled this standby state.) does not indicate it's disabled by group policy settings but something related to Device Guard.

Start > Run > Gpedit.msc -> Computer Configuration -> Administrative Templates -> System -> Power Management -> Sleep Settings

There are two options:

Allow standby states (S1-S3) when sleeping (plugged in)
Allow standby states (S1-S3) when sleeping (on battery)

Set them to Enabled.
