Hello Dell,
I'm unable to adjust my own brightness levels on my 2015 XPS 13 using the hardware keys F11 & F12. Using MS 8.1
I have taken these steps to try and resolve the issue:
- New Bios
- Re-Install GFX drivers
- New Keyboard from Dell
I just had one of your hardware contractors replace the keyboard, and try to troubleshoot the issue. However, we are still in the same boat.
Is there anything in the latest Windows updates that might have turned the function off?
Short of "refreshing my system" is there anything else that I can try?
