Hi
I am using Lenovo x230 model laptop
Configuration : I5-3320M, Hd4000 graphics

I am using unlocked MSR bits mod bios
Presently I am not using Any CPUpower management ssdt patches , in clover I select PluginType enable

I am using normally , I reed a article about Ivybridge Power management , in that ivybridge must patch using ssdtgen.sh to enable power states ,

but I am not using it !

Am I need to use ? ( cause I am already patched my bios )
