Model : Asus rog Zephyrus g16 GU603ZV 2023
Bios : 313
VBIOS: 95.07.21.00.17
I am experiencing issues with brightness control and switching between integrated and discrete graphics on my ASUS ROG Zephyrus G16. After switching from ECO mode (integrated graphics) to Standard mode (discrete NVIDIA GeForce RTX 4060), I lose the ability to adjust brightness.
A temporary workaround is to remove the NVIDIA GPU in Device Manager without uninstalling the driver, after which brightness control starts working again, or simply rebooting the system directly into Standard mode.
The issue persists after resetting the BIOS and reinstalling the system.
