Question about the NUC11PHKi7C and power plans.

[BHarr8]

Testing on both Windows 10 and Windows 11 the NUC11PHKi7C seems to do someone at the BIOS/driver level that completely disables the ability to change power plans. "Balanced" is the only one available and in advanced options there are no setting for anything other screen and sleep timers.

I even manually added ultimate power plan (on both 10 and 11) and this change is completely ignored.

Is this the intended functionality or is the new nature of this hardware not correctly interfacing with Windows?

Hello BHarr8, 

Thank you for posting on the Intel® communities.   

In order to better assist you, please provide the following:  

1. What is your BIOS version?

2. Can you take pictures of the "power plan" settings?

3. Are you trying to set the "power plan" from the BIOS or from Windows?

Bear in mind that our support is for Windows 10 since Windows 11 has not been released officially.

Best regards,

2. power plans:

no hardware options:

registry correctly shows all plans, including ultimate:

3. I have tried using the default plan and creating a custom plan, in both cases Windows only shows 'balanced' and provides no control over hardware power plans individually.

It does not matter if I use Windows 10 or 11, the power plan options are missing in both.

Hello BHarr8, 

With the information provided, I was able to investigate further. Based on the research performed, this seems to be an issue with Windows itself (Microsoft).

This could be related to a block or limitation from the Microsoft side, I recommend you to check with them directly for further instructions.

I have solved this problem by using the S3 standby fix required to solve the overheating while sleeping issue in the NUC11PHKi7C.

I suspect that incorrect implementation of modern power states is responsible for both issues, overheating while sleeping and Windows being unable to show/modify power plans.

Correcting this BIOS bug should fix both issues and allow the NUC11PHKi7C to function normally without needing to force legacy power states.
