I couldn’t really find the graphics card drivers on Lenovo’s site, and I use nvidia not AMD.
I Installed some drivers that were from nvidia, but they were for display, so I dunno if it was the graphics card.
I also can’t find those settings in BIOS (After clicking F2 which is the setup config). I have changed graphic card setting from switchable to UMD, but I think it’s the really default one (or the Intel’s). I dunno what I really did.. I just can’t use nvidia card now for sure. I have found that I would need to modify my BIOS (In pretty complex way..) to make the change graphic setting from “dynamic” to “fixed” option available. I’m not sure if it’s even worth it.
