Intel Core i5 9300h 35W power limit with active GPU

Hello. I ran into a problem with the i5 9300h power limiter. The declared power level for this CPU is 45W. It really works at this power level, keeping the maximum cores frequencies, while not overheating (in my case). However, when you turn on the GPU, after 30-40 seconds, the limit of 35W is activated. It is worth mentioning that the load level of the video adapter does not affect how soon the limit is activated. The system does not overheat and is serviced twice a year. All components are working properly.

Notebook - OMEN by HP 15-dc1065nw
Intel(R) Dynamic Tuning components removed. The regular setup program "Omen Gaming Hub" does not contain any settings that allow you to change the situation. BIOS version F.27. The BIOS contain the CPU power adjustment settings: 20, 25, 30, 35, Default. There is no difference in the operation of the processor under the conditions I specified with the settings "35" or "Default".

(I did tests for screenshots with the browser turned on, so the results in cpuZ will certainly be below normal)

Some laptops use an embedded controller for power management. This can be programmed to reduce the CPU turbo power limits when the Nvidia GPU becomes active. There is no simple solution for this problem.

The person that originally bought this laptop should have returned it immediately for a full refund. It is defective by design.

Edit - Try installing any HP power management software and set it to maximum performance. Set the BIOS power setting back to Default and see if that makes any difference. You might be forced to run the HP software.

Thanks for the help. Unfortunately, the only utility compatible with my device that could contain power settings has been mercilessly mutilated by HP. For my configuration, the "Performance" option is not available in Omen G Hub. I understand the lack of Mux switch, but the reluctance to add such an elementary setting ... I'm extremely offended.
