Does anyone have experience using the Lenovo Advanced Menu?

Hello,

I got my bios unlocked for my Lenovo X1 Carbon, in order to get an dw1820a in there. Additionally, I got the advanced menu. I did some poking around and saw there is multitudes of options to make use of.

I was wondering if anyone specifically had used the CPU power management tab to get extra battery out of their Hackintoshes
