Itautec W7730

Hey dear,

I managed to install on a Laptop Itautec w7730. OSX el capitan
Not working: Audio, HDMI, image is a bit buggy, battery meter. When I can operate the keyboard and touchpad USB does not work.
If I install any kext it kernel panics (Intel CPU power management kernel panic.) Detail, I'm choosing the option nullCpu in multibeast .. Someone of a help ??! I need to install some kext for cpu?

Note: I created an image to restore if you give some kext problem, but all I install...
