Windows 11
I have a Dell XPS 15 9510 w/ i9-11900H that I've done a thermal paste and pad replacement on a few months ago. Setting the Windows mode to "Power efficiency" reduces power and a modest turbo boost drop (but still some)...performance and temperatures are still good. However, I've noticed that when I plug the machine in, the Power efficiency is not in effect, machine runs at full power/speed, and machine still bounces off of 100C threshold even when doing simple productivity apps. I don't notice throttling but it still bothers me. Disabling turbo boost works and temperatures drop significantly, but there is also a performance hit. How come the "power efficiency" mode doesn't apply when plugged in and is there a way to enable it (or set maximum boost frequency) when both on battery or AC power? Thanks.

Check whether SpeedShift is switched on.
If not then enable it in the BIOS.

You can disable "Turbo".

You can also unlock options to change the CPU frequency of a custom power plan. (P_Core and E_Core)

Use the PowersettingsExplorer tool

Then you can modify the CPU frequency :

Thanks...I forgot about that app (PowerSettingsExplorer). I'll download on my laptop and try that out.

Power Settings Explorer question. For 11th Gen and below I only need to enable and set Maximum processor frequency correct (i.e. all cores are the same)? For 12th Gen and above (with P-cores and E-Cores) I think Maximum processor frequency is for E-core and Maximum processor frequency for Processor Power Efficiency Class 1 is for P-core? I just want to double check.
