bei Atlas is not at fault here; it's dependant on your laptop.
Some laptops' BIOS allow you to disable it so you can use other power plans in Windows - others can't. If you try using Google to see if it's possible for your laptop, but there's nothing we can do - it's a hardware lock.
It's for power saving but also the safety of the hardware components; make sure you research this thoroughly before you continue.
Hopefully, that helps :)
