Dell Precision M4600 bios unlock for hidden functions

Hello there,

Im Jerry and just new here. A friend of my told me that maybe someone
here can help me with an unlocked bios for Dell Precision M4600.

I want to have the hidden function from the bios, like the settings of the minium fan speed etc.

I would appriciate it if someone can unlock this for me.
Can someone help me? Thanks a lot.

Jerry
