Just to add to this on observations. If you apply discreet gfx through control centre and reboot. and then decide to go into bios. The bios screen is broken, it only shows up on the left hand side using about a quarter of the screen making it unuseable and unreadable. you have to force shutdown the laptop, restart to windows, apply hybrid setting for gpu then go back to bios in order to use it. i can provide a photo if it helps? thanks
