NiPeGun Posted December 9, 2013 Share Posted December 9, 2013 My BIOS is locked and doesn't have the option to enable/disable de HD4000. I extracted the DSDT and there is no reference to the IGPU inside. Maybe it's just not codded into BIOS leaving just as dead hardware. . So, can be added by DSDT modifications independently from the BIOS??
