Hello guys, the backup file belongs to a lenovo b50, the external Nvidia GPU was disabled from the BIOS settings and the laptop worked fine on the internal Intel GPU, but my customer enabled the external GPU from the BIOS and that made the laptop to be no display, now when I turn it on, it gives me 2 beeps with a black screen, I can not turn the MB into UMA, so can you guys edit the backup and disable the external Nvidia GPU?
By the way I checked the ram and other things, there is no obvious problem other than the GPU, I am considering the option of reflowing the GPU, but I don't prefer to resort to such option.
