Question Why is my laptop constantly running in turbo boost?

I don't know if its normal for my cpu on my laptop to constantly be running in turbo boost. I have a new HP OMEN 15-dh0012ni. Had issues after a driver update which caused my gpu to be undetectable and had to reinstall cpu drivers as it was caused by a PCIe driver not functioning properly. CPU temperatures and fan speeds have been acting up (getting really hot with around 11% cpu usage then fans go crazy the temp drops) as well as its always running at around 4 GHz on my i7-9750H which has a base speed of 2.60 GHz. Any insight on this?

I had a fairly similar problem, maybe this will be useful. Check the minimum CPU state in your current power plan settings. If the minimum state is unreasonably high, over 50% (whether the laptop is charging or not), try lowering it to ~10%.

Thanks for the reply just had a look at it now and it seems that it is on 5%.

Hello,
Assuming you still have the problem, I have just found the solution. I have a very similar machine, HP pavilion Gaming having i7 9750H, GTX1660 Ti, and had the same problem for quite some time, which also began after updating my drivers. The CPU would always be running inTurbo mode, aroung 4GHz, and running at 80 - 85 C when connected to supply, otherwise running very cool, around 45 C on battery.

I used to blame the GPU for removing the power limit when connected but it turns out there is an issue with the power management in windows. In Ubuntu 18.0.04 the temperatures used to be fine, around 55 C.
As written in one of the above replies, changing the CPU state will be effective, but there is a caveat, the power state controls the p - states (roughly frequency levels) for all configuration modes, except the power Supply Connected with the slider on "best performance" in the battery indicator.
i.e. For the laptop
1) running on battery and slider anyway between Best Battery Life and Best Performance,
2) and, for the laptop connected to supply for the slider at "Best Battery Life" and the intermediate levels,
the processor will not go to the Turbo Frequencies and any changes applied to power states in "Advanced Power Settings" will be visible.

For the last case of Supply connected and Best Performance, the battery states, (minimum or maximum), have no effect and the processor stays at the maximum possible frequencies, even with no load.

Also note that the power states are p-states (1) (2), and not exactly the frequencies, so the maximum and minimum frequencies will change in steps (multiplier and FSB (3), and we will not get all 100 values. Similarly, the 0% would be the lowest state, which is around 800 Mhz for us I think.

Thanking You
