Question "CPU throttled at 78% by Windows" Problem!

Nov 22, 2019
Hey there! I bought a week ago a new Lenovo Ultrabook 14" IdeaPad S540 IML with I7-10510U, 8GB RAM, 512GB SSD, GeForce MX250 2GB, No OS, got it at a very good price and i was very excited with my best buy at that moment!
As soon as i installed Windows 10 and all the drivers on it, i performed several userbenchmark tests and all the components work fine apart from the following warning which bugged me now for almost one week:

"CPU throttled at 78% by Windows. Ensure maximum processor state is set to 100% via Settings > System > Power & sleep > Additional power settings > Change plan settings > Change advanced power settings > Processor power management > Maximum processor state. "

Userbenchmark Result

Another detail worth mentioning is that i tried to dual boot this laptop(Windows 10 & Linux) and failed completely 2 times, first i tried to install Pop OS and failed because wifi didn't work properly, second time i tried with Linux Mint and that gave me an important info about the possible existence of a "overheating" problem, everytime i tried to boot from usb Linux Mint, during boot it said that "Core temperature above threshold, cpu clock throttled (total events = ?????)" followed by "Package temperature above threshold, cpu clock throttled (total events = ....)" and it would return to a black screen until i turn it off.

Also i tried disabling throttling from the group policy, aswell as setting the maximum processor state to 100%, that value coming with the installation by default.Tried all kinds of tips and tricks in order to solve this, but i feel like it's above my capabilities at this point and that's why i need some help.I have a week left to return it.Should i take this warning as a serious hardware failure?
The laptop it's amazing, snappy, nice design and all that, but if i can't do various things for example not being able to install Linux, and this throttling problem then i can't enjoy it to the max even though it has some of the best components for the price. Thanks!

Here are screenshots of HWmonitor during and after stress testing:
