Brightness not working windows 10

Windows 10 brightness slider not working [Completely Fixed]

Brightness issues on your computer are usually associated with display drivers, and other power settings, which you may or may not be aware of.

If Windows won’t let you adjust brightness on your PC or laptop, these are the first two areas to check for besides trying the usual common fixes such as restarting your computer or updating Windows.

While updating Windows will work to install the latest drivers that could be pending on the updates tray, there are other solutions you can try that are listed below.

Keep in mind that every model of your laptop, as well as operating systems, are different, even as you check on the settings for each fix.

You can apply the below solutions for any type of laptop, such as Asus VivoBook, HP, or Dell when the brightness is not working.

What can I do if the laptop brightness won’t change?

1. Update the display adapter drivers

Install the appropriate drivers missing from your laptop that can cause the brightness adjustment problem. If this does not work, we recommend trying a 3rd party driver updater.

The tool will show exactly what drivers need updating. You’ll have both the option to update several drivers at once, if needed, or choose the Update button next to each driver.

It is designed to do the whole driver downloading and installing job instead of you. This is the best way to avoid permanent damage to your PC by getting the right driver versions.

2. Enable adaptive brightness

A feature of the Windows operating system, adaptive brightness uses an ambient light sensor to automatically adjust a display’s brightness to the surroundings.

3. Enable the PnP Monitor driver

PnP stands for plug-and-play hardware devices, that work without having to install a driver. You consider it the generic driver for the display that will automatically get installed by Windows.

4. Update the registry

If you’re still unable to adjust brightness on your laptop, try updating the registry. Back up the registry before you modify it, then restore it if a problem occurs.

This solution contains steps that are part of modifying the registry. Please note that serious problems may occur if you do this incorrectly. Ensure you follow these steps correctly, and carefully.

If this issue persists, you should also ask for a specialist’s help. If your screen is faulty, updating your drivers won’t solve the problem.

If the display is affected by hardware issues, then most likely, you’ll need to get a new display.

If you’re still having trouble adjusting brightness on your Windows 10 computer, post a comment in the section below and let us know the details.

Brightness Control not working in Windows 10

I had my laptop, which is an HP Envy 15 ae116tx model, fixed in a service center because of screen discoloration (it’s a touchscreen btw). They replaced the display panel. I got it back after a month and I noticed that the screen brightness control is not working anymore. The brightness control in the taskbar is greyed out and cannot be adjusted, the function keys in the keyboard are not adjusting the brightness as well, and there’s no adjustment slider in the power options.

I’ve searched online and tried any possible solution there is, but unfortunately, none of them worked for me. I’m very frustrated now and I don’t know what to do. The following are the solutions I tried:

DEVICE MANAGER SOLUTIONS

1.) Updated the display driver as suggested, it did not work.

2.) Disabled and enabled the display driver, it did not work.

3.) Uninstalled the display driver and reinstalled it, rebooted my laptop, still it didn’t work.

4.) Disabled and enabled the Generic PnP Monitor, it didn’t work (it was enabled in the first place btw).

5.) Uninstalled and reinstalled the Generic PnP Monitor driver, still didn’t work. I also clicked «show hidden devices» and uninstalled all the drivers under Monitor, including the hidden ones, reinstalled them and still didn’t work.

6.) I rolled back to the old versions of my display drivers, still didn’t work.

7.) I switched to Microsoft Basic Display Adapter, brightness still cannot be adjusted.

1.) I updated my Windows, installed the anniversary update. I installed and updated all suggested updates in the Windows Update tab, but it didn’t fix the brightness control problem.

2.) I did the regedit solution, there’s no KMD_EnableBrightnessInterface2, so I made one up and restarted my laptop, still didn’t work.

3.) I can’t remember where I found this solution, but I did something about changing a value for a key/sub-key in regedit.

I did more solutions as I can remember, but none of them really worked. I considered refreshing my operating system in hopes of making the screen brightness adjustment work, but I want to know if there are more other options. Since I had the display panel replaced for my laptop, I don’t know if it has something to do with that.

Also, I can only adjust the brightness manually with the Intel HD Graphics Control Panel but of course, I don’t want to resort to that since I still don’t get the default screen brightness control. If nothing really works, I might have to contact the service center again to ask for a solution.

I hope someone can help me. I’m really exhausted looking for other options.

This is a little ridiculous. I’m trying to change my brightness, which used to be a press of Fn + F2 and now I have to go into settings restart my computer run as compatibility which doesn’t even show up for me. My eyes are hurting and I just want windows 8 back. Oh wait, that also used to be at the touch of a few buttons and it would take me back. Now I have to apparently have a recovery drive on a flash drive. Why do you make everything so hard for us? Why cant it be as easy as before? What is the purpose, even, of changing it to be more difficult. I’d like to say I’m quite adept with computers, but if you ask people to do these basic tasks when even I can’t I’m surprised you aren’t flooded with complaints.
