This device, priced at €2,350, was a real pain.

I struggled with overall performance; sometimes the cooling wasn't sufficient, sometimes something else entirely. This is what I ended up doing.
Updating the BIOS to version 1.17 solved the cooling issue.
Using throttlestop, I set the maximum processor power to 95W in the TPL tab.
I then struggled with graphical artifacts (sprites). The only solution that helped was using Windows 10 instead of Windows 11. The laptop works perfectly and without any problems. All drivers installed perfectly.
This laptop simply refuses to work properly with Windows 11.
