Dell G15 5515 Screen Brightness Issue

I have a new Dell G15 5515, AMD Ryzen 7 5800H, and Nvidia GeForce RTX 3060 on Windows 11 Pro 23H2.

I am unable to change my laptop display brightness – it is permanently stuck at 100%. The Windows toggles / sliders move, but the brightness doesn't change (even on Battery Saver).

I am on the latest Dell BIOS ver. 1.16.0 and Nvidia driver ver. 555.85. I have already followed most of the troubleshooting guidelines online of changing the power plan settings etc., and even reinstalled Windows, but the problem persists.

There are several other forums with people having the same issue since last year. Disabling Hybrid Graphics in Bios allows the brightness to be changed, but this is a temporary workaround (that increases battery consumption), not a permanent fix. A solution should not come at the cost of an important feature. Downgrading to an old driver and waiving future updates is also not a viable permanent solution.

@DELL-Cares Could you please help to escalate this to the relevant department that would be able to work on a permanent fix?
