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

Same. New Intel drivers didn't make a difference. Will continue to investigate.
In fact, I was using driver version 10.18.10.4252. The driver from Dell is 10.18.10.4242. Few minutes after installing the Dell driver, Windows automatically updated me back to 10.18.10.4252. If the driver from Dell would have worked, I would have been concerned. Is there a way to turn off automatic update?
______________________________________________________-
To access the option "Never install driver software from Windows Update", open the Control Panel by right-clicking the Start button and selecting Control Panel. Navigate to System and Security > System > Advanced system settings. Click the Hardware tab, click Device Installation Settings, and select the “No, let me choose what to do option. Select “Never install driver software from Windows Update.”
Also you can download and run the “Show or hide updates” troubleshooter for Windows 10 from Microsoft.

Unbelievable!!! I had same problem on my Dell 7548 after the last driver upgrade on Windows 10. I believe then I have the last and good drivers for my configuration.
My F11 & F12 brightness key was dead. But now after last check I see an update for AMD video card and my brightness key is working again.
Thanks mate!

Sorry for my English.

Thank you for your suggestion Abdullah, but if the solution was as simple as updating my graphics driver, I would have never have posted on these forums. The problem is, I have updated my graphics driver, from Dell's website and from MS update and the issue remains. Dell, may we please get an official response to this issue? It sounds like many people are having a similar problem.

One of the issues i found with my monitor brightness was as follows:
1. updated from windows 8.1 to 10
monitor brightness worked great
2. Ran windows updated downloaded nvidia and intel drivers
broke brightness controls
3. rolled back drivers
Brightness was working again
4. Checked monitor drivers as old windows 98 laptop had this issue as well.
found one of my remote control programs had replaced the generic Microsoft driver with its monitor driver.
Was either, teamviewer or vnc.
5. restored the generic Microsoft monitor plug and play driver brightness now works fine.

I solved this problem by doing this:
go to Settings>Update&Security Windows Update
type in the Search box :"update device drivers", click on Update device drivers
click on Monitors>Generic PnP Monitor and just click enable

Interesting DROPS76. I haven' t tried this one yet. I did a clean install of Windows 10 with UEFI enabled. Secure boot is disabled, but I think I disabled Legacy boot. I wonder why that would have an effect on screen brightness. It wouldn't bother me much if the Fn+F4/F5 shortcut stopped working, as long as I could control the brightness from the action center. I'll try this method later today and report back. Thanks again.

Drop76's suggestion worked for me, having tried everything else I could think of.
The only thing I couldn't do was enable legacy boot it said there was no boot device (tries PXE then fails with no boot device found).
However, just disabling UEFI in the BIOS, for some weird reason, fixed the problem. It literally all just worked as soon as it had finished booting up. My driver is 10.18.10.4252.
Like you, I really do wonder why this would affect the problem.

That worked drops76! Finally, I can control my brightness again. Thank you. When I did a clean install of Windows 10 a few months ago, I had disabled Legacy Boot for security reasons. Once I re-enabled legacy boot and rebooted, my brightness controls work correctly.

So the question is, why does enabling the Legacy Boot option in my BIOS have anything to do with allowing me to control brightness settings? By enabling Legacy boot options, doesn't that introduce a security risk by allowing someone to boot to a usb or cd live disk? Will Dell fix this soon so that we can disable legacy boot and still be able to control screen brightness?
And on an unrelated note, while looking around in my BIOS, I noticed that "Intel Rapid Start Technology" is grayed out. I may have missed a step while reimaging this laptop. Is it possible to enable that feature without reinstalling Windows? This laptop used to boot to the login screen in about 11 seconds. I just timed it and it takes 26 seconds. Does anyone have any instructions on the correct way to configure Intel Rapid Start? FWIW, I have a 750HDD and a 32GB mSATA SDD for caching. I have Intel Rapid Storage installed and configured but I guess Rapid Start is a seperate

I had the same issue with my alienware 17, I went into device manager, and had to enable the Generic PNP Monitor for the brightness settings to work. Hope that helps.
