Some issues with ThrottleStop

[Baban_]

Ok so i have an issue that's being there since a while back
I fully undervolt everything in my laptop to have a better battery life and better temps (because yeah gaming laptop is not really know to be really power efficient on battery)

But i don't know why, as soon as i plug the charger my cpu draw at least 12w min (that also increase my temp quite a bite)
also i wanted to know what exactly is PKG demotion / undemotion under the C States

What Windows power plan are you using? If you are going to use ThrottleStop to change the Speed Shift EPP value then you should try using the Windows High Performance power plan. The FIVR monitoring table shows that Speed Shift EPP is set to 178. Your EPP requests of 128 or 190 that you have entered into ThrottleStop might be ignored if Windows is writing a different EPP value to the same EPP control register. You do not want a situation where two different programs are writing different values to the same EPP register.

Does using a really big EPP value help reduce power consumption? I know this makes a CPU run slower but sometimes all this does is it makes a CPU less efficient. A slow CPU might increase overall power consumption, not reduce it.

as soon as i plug the charger my cpu draw at least 12w min

When you plug in your charger does your Windows power plan change? Does the screen get brighter? How are you measuring power consumption? Is ThrottleStop setup to change profiles when you plug in a charger? When I plug a charger into my laptop, power consumption stays more or less the same. My power plan and ThrottleStop settings are more or less the same whether plugged in or running on battery power so I have never noticed any significant change to power consumption.

If you want to improve battery run time then have a look at what programs are running in the background on your computer. When a computer is idle at the desktop with only ThrottleStop open, the individual cores should be averaging 99% of their time in the low power core C7 state. That is how modern Intel CPUs save power. One bad driver or one bloated program running in the background can increase power consumption and reduce battery run time.

The Package Demotion and Undemotion stuff slightly changes how much load it will take for a CPU core to transition between one C state and another. I think having all of the Undemotion options checked helps improve the C state percentages which in theory might help battery run time when you are running on battery power. With most modern CPUs, these adjustments, whether they are checked or not checked, seems to make very little difference.

First of my 1st preset is when i'm plugged in and the 2nd is on battery (the 3 is when i'm at 55%) but as you can see plugged it with the EPP maxed out change nothing in power consuption

Yep 1st it change from my battery saver mote to plugged in mode ( just increase the IccMAX, enable turbo boost, change the time resolution via TS to 0.5 disable C1E) also i have a Lenovo laptop (I'm not using the OEM control panel bcs i't a crap so I use Lenovo Legion Toolkit) and so it change from Quite mode on battery to Performance (i tested plugged in it does not change power consumption) and change the windows power plan also change nothings

Already what i did, my windows start with 90 processus in the background and my C0% stay most of his time at 3max or if i look via Process Explorer my laptop stay 99.8% in idle so yeah

Thxxx

Also looking in the C State section when plugged in my cpu stay at C3% while the same load (just Discord and Opera GX) on battery it will stay mostly at C7%
