I have just bought a new PC from a PC Builder, but they disabled all the power savings settings in the BIOS, and I think that affected the ability to use any of the sleep states because that was the state whilst Windows was installing.
I first noticed a problem when I tried to change the power button settings –
I noticed that Sleep was missing:
---- Power and sleep button settings --- When I Press the power button: Do Nothing Shutdown Turn off the display When I press the sleep button: Do Nothing Turn off the display --- Shut-down settings --- [ ] Lock Show in account picture menu
I tried the "Change Settings that are currently unavailable" option,
but that made no difference.
So I then tried
powercfg /a, which returned the following:
The following sleep states are not available on this system: Standby (S1) The system firmware does not support this standby state. The current power policy has disabled this standby state. Standby (S2) The system firmware does not support this standby state. The current power policy has disabled this standby state. Standby (S3) The current power policy has disabled this standby state. Hibernate Hibernation has not been enabled. Standby (S0 Low Power Idle) The system firmware does not support this standby state. Hybrid Sleep Standby (S3) is not available. Hibernation is not available. Fast Startup Hibernation is not available.
I assumed that the BIOS settings must be disabled and that after enabling them I would see those missing states, but it's still the same.
Someone recommended activating the Hibernate – they thought that would fix it, but all it did is add some rows to the top of the report
The following sleep states are available on this system: Hibernate Fast Startup
My motherboard is an ASUS Z270-K.
Does anyone have any suggestions other than a reinstall?
Additional information asked for by Andrew Morton:
- Which BIOS is it?
It is now PRIME Z270-K Version 1207;
Release Date: 22/06/2018
- What Power Settings did you use?Ai Tweaker\Internal CPU Power Management Intel Speedstep = Auto Turbo Model = Enabled
Advanced\Platform Misc Configuration PCI Express Native Power Management = Enabled
Advanced\CPU Power Management Control Intel Speedstep = Auto Turbo Model = Enabled CPU C States = Auto
Update 20:50 11 July 2020 – Found where Sleep States are found in BIOS:
Advanced\APM Configuration ErP Ready = Disabled
ErP Ready Setting is now updated
Advanced\APM Configuration ErP Ready = S4+S5
powercfg -a has not changed with respect to sleep states. I now have a "The hypervisor does not support this standby state" now that I've enabled virtualization for WSL2 to work.
Update 21:20 11 July 2020 – Found out that S5 means off, so not sure what the point of this is, so setting it back to disabled.
Update 15 July 2020 – On a previous go through of I found information from Microsoft outlining some special setting for enabling the power states: Allow sleep states.
I didn't find it easy to understand, but today I found out how supposedly I could use powercfg with the information found on that page to do it.
So I ran
powercfg /setACvalueindex scheme_current SUB_SLEEP ALLOWSTANDBY 1
However this comes back with the message "Group policy override settings exist for this power scheme or power setting."
I have no idea what this means or how to fix it.
I tried creating a new powerplan and substituting scheme_current
with the GUID of the new plan; however, the same message appears.
