It doesn't suffice to *use* the Intel as the primary (Nvidia doesn't support any useful VESA mode anyway), you have to disable the switchable graphics feature completely, otherwise the Nvidia GPU runs at full steam and will overheat the laptop, which after some time will shut down. If for some reason you boot Windows after you have done the above, the BIOS settings will reset, so keep that in mind. --=20 Aram H=C4=83v=C4=83rneanu
