DELL XPS 15 Monitor does not dim or brighten on windows 8

Jump to solution

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

Installing a new update for windows that just came out, and downgraded the driver to the one on the dell website. Brightness settings now work.

Cheers,

Ian

Xtreem0,

 

Advanced power settings, turn off adaptive brightness, seemed to help for me.

Hmm Tried that out but still does not dim. I can only adjust the brightness when the laptop first boots (when UIEF boots)

Xtreem0,

 

Not on that system at the present time.

 

Hit the Windows key and the x keys at the same time, power options, advanced.

 

There may also be a setting in the battery life settings.

 

Press Fn and F2 or F2 and bring up the battery

 

Uncheck the Dell Extended Battery Life
