Hi Guys,
I recently upgraded my computer to windows 8 on the new XPS 15 laptop and I have been experiencing an issue where I cannot adjust the screen brightness. I am currently running the computer in UEIF mode with secure boot enabled which seems to be a part of the problem. I can adjust brightness when the dell logo appears but once the circles appear under the dell logo the brightness cannot be adjusted. Nothing else on the system appears to be working incorrectly.
Any thoughts?
Cheers,
Ian
