Dell Latitude 3410 Bios Undervolt

[thebbot]

So I've been poking around the internet for a while and I've successfully undervolted one of my dying laptops to improve performance drastically, so I'm hoping I can do something similar with the latitude 3410. Problem is, the bios locked voltage changes, and it wont let me downgrade past a certain point. My goal is to either be able to unlock the bios, or to find some way to balance power better between the cpu and integrated gpu, as when both are in high usage it caps out at around 20w used. If anyone has any advice on how to go about this I'd appreciate it. If anyone needs any more info I'll gladly hand it over.
