W520 discreet graphics option in BIOS (no graphics card in device manager)

#1 Post by u666sa » Tue Sep 26, 2023 3:39 am

When I have optimus enabled in BIOS, everything works fine. I see two graphics cards in device manager. (windows 10)

When I go to BIOS and select discreet graphics. I do not have Quatro 2000M or any other graphic device in device manager, nor can I install display drivers from NVIDIA.

What's happening?
