Power limit throttling

[dominic03]

Unfortunately, my HP laptop is under performing while playing games.

When both the CPU and GPU are under load, I'm finding that my CPU slows down, which has a serious impact on the laptop's performance. I've looked into why this is happening and it appears to be Power Limit Throttling -- when the CPU and GPU draw too much power for a set amount of time, the CPU will automatically slow down to reduce power usage. This has nothing to do with the maximum amount of power the computer can output or with temperature of the CPU. In fact, I was previously able to avoid this using Intel's Extreme Tuning Utility or TechPowerUp's ThrottleStop utility.

However, after updating my system's BIOS, I am unable to use either utility to prevent the throttling from occurring. So something was changed in a recent BIOS update to lock the Power Limit.

I've tried reverting to my previous BIOS (F.19) however it will not let me as it always says "Cannot find signature file". So I will have to take a different approach to this. Is there anything that can be done to increase this power limit, to force a BIOS downgrade, or to allow utilities to change the Power Limit?

Thank you for any help you are able to provide.

Computer specs:

HP Laptop bs-067cl -- purchased in 2018
CPU: Intel Core i7-7500U -- max speed of 3.5GHz but runs at 2.7-2.9GHz when throttling

GPU: Intel HD Graphics 620
