Can't adjust brightness after installing Windows 10
Hello. I Have a Dell XPS 15 L521X. Recently updated to Windows 10 and I can no longer adjust my brightness up or down.
Right now the display is pretty dim. I would guess about 30% - 40% brightness. In Widows 10 I found about 5 different places to adjust your brightness and I made sure all of them were set to 100%. I have my power plan set to high performance and I went into the advanced settings and turned off adaptive brightness and made sure both display brightness & dimmed display brightness are both set to 100% on battery and plugged in. Rebooted and still dim.
My question is, on Dell laptops, should Windows have full access to control brightness? Or does Dell override Windows with their custom software for display settings? When I bought this laptop in 2012, the software, at the time, was called Dell QuickSet. Is that the application responsible for controlling screen brightness? And is it required?
Thank you,
Mike

I had the same problem and I solved it too by activating legacy rom.
This reminds me on a similar problem in the past. I tried to install Windows 7 in UEFI mode and as long the legacy rom was disabled it freezed on boot. So I installed disabled it and after some month (after windows installed some updates) I was able to disable legacy rom again.
I think the problem is the Intel GPU driver as if you uninstall it the default microsoft gpu driver is able to control the brightness.

Confirmed WarrenMC81 and Mike10370's responses did the trick on a Dell XPS 15 L521X.
I previously got it working by disabling secure boot and preventing Windows 10 Pro from updating the drivers.
To apply this fix, I enabled secure boot again, used the Intel Driver Utility from www.intel.com/.../detect to apply the latest Intel drivers (rather than Dell ones). Then made the registry change as described and the brightness control buttons are working correctly.
Many thanks for your research on this one, very much appreciated!
Cheers,
Andy

So, this registry hack no longer seams to work in the newer versions of Windows 10. Anyone find another workaround?

Mike - did you review my post just above this? It's still working for me, and there's no registry hack involved.

Same problem here. My unit is Dell 3162.
@doctorkb, on my unit, the generic pnp monitor has enabled by default. The registry hack also doesn't work. Do you know any other option to solve?

Same was here. After last update problem was back again.
What I did was go to intel site for latest drivers for HD4000, install, then apply FeatureTestControl registry to both in my case subtrees (I had 0000 and 0001).
After reboot it works well again.

That might fix the brightness issue, but what features are you loosing by changing the Intel HD 4000 driver to the Basic Microsoft Driver? I know that the Dell XPS 15 L521X also has an nVidia 640GT for any graphic intensive tasks, but 90% of the time I use my laptop for work or web and the Intel HD 4000 includes improved power savings , not to mention an improved multi format codec engine, improved 4K video decoding, quicksync for fast transcoding, and alllows for three external displays. Would any of that work with the Microsoft Basic Display Adapter?
I tried the registry hack again last week, and it alllwed me to adjust brightness after a reboot, but I can no longer shut down my laptop from the start button. I have to hit control alt delete and then *** down. I wish Dell would chime in.

Hi doctorkb, I did see your comment about using the Generic PnP Monitor driver.Thank you. I tried the registry hack again last week and it worked, sort of. now I can't turn my laptop off from the start menu. See my other post for more info.

I think you misread.
It's NOT about changing the DISPLAY ADAPTER driver, it's about changing the MONITOR driver. You should still get full use of your display adapter's functionality.
I don't have any issues shutting down - any chance you bumped something else while you were editing the registry? What happens when you try to use start menu -- the functionality should be the same as on the lock screen...

I have the same issue on my Dell Inspiron 13 7000 series. I did:
Control Panel > Device Manager > Display Adapters > Intel HD Graphics 5500 > Driver > Update Driver > Search Automatically.
It fixed.
18:35 on 25-Dec-2016: Sorry bro, I did as above; it fixed but when I try pressing the brightness button then It come back problem again: can not adjust the brightness. Hic hic
19:00 on 25 Dec 2016: I even try downloading and installing the latest Intel Graphic Driver (issued on July 2016), but just after a while, the screen comes back very dim.
I accidentally discover this: Setting --> Display --> uncheck the box "Adjust my screen brightness automatically".
Sorry, but stupid Windows!!!!
