Thank you for posting your query on Microsoft Community.
As per the issue description you are facing issue with the brightness on your computer. If all settings are fine then the issue could be if the display drivers get corrupted or need to be updated.
Laptop Screen Brightness Won't Adjust
The issue could also be related to the Display drivers and other updates. I want to inform you that updates will be released by Microsoft. So, I would suggest you to keep checking your Windows updates not only important one but optional too. If any available try to install them and see if it helps you to fix the issue.
My Laptop Brightness Won't Work Windows 10
First try to install all of the Windows updates available and if issue persists, try to update the Display drivers by following the steps provided in the article mentioned below.
If issue still persists, then install the drivers for Windows 8/8.1 from the manufacturer's website in compatibility mode and check if that works.

Stand near the center of the circle, then light up bothcandles again. Light them up fast.The entire area will start to be filled with the red organic matter. The two candles besideit will die.

Be fast about it because the candles will be blown outin a matter of moments if you don't do this.Exit the room and head straight to the next room right in front of you.To the left is another alter, and to the right is another weird circle.Touch the altar to let it prick you, then stand on the weird circle andthe two candles will die again.
After upgrading an older Lenovo laptop to Windows 10 recently, I ran into a very annoying problem. For whatever reason, the ability to adjust the brightness stopped working. Pressing the brightness keys on the keyboard would show that the brightness level was going up or down, but nothing actually changed on the screen! It was the weirdest thing I had ever seen.
The first thing I thought was maybe there was some hardware issue and Windows 10 was not recognizing the key press properly. I decided to try to change the brightness level in the OS itself. I opened Action Center and clicked on Expand and then tried to adjust the brightness there, but again nothing happened! Now I was really confused.
I also tried to go to Power Options and change the brightness there, but again it didn’t make any difference on the actual display. The second thought that popped into my head was that it was a driver issue. I went to the Lenovo website and downloaded the latest driver I could find for the machine. I was hoping that would fix the problem, but it didn’t!
At this point, I figured it could be that the latest driver doesn’t yet support Windows 8.1 properly and therefore I need to try out the standard or basic Windows graphics driver instead. In the end, this is what fixed the problem. Now I just have to wait till Lenovo releases an updated driver for my older Lenovo laptop. Here’s how to fix the issue temporarily.
First, open the Control Panel and click on Device Manager:
Next, expand Display Adapters and then right-click on the graphics card installed on your system and choose Properties. It could be something like Intel HD Graphics, etc. It’ll depend on what kind of graphics card you have installed, but there really should only be one or two listed max.
Now go ahead and click on the Driver tab and then click on the Update driver button.
Next you’ll have two options. You want to choose the Browse my computer for driver software option.
We’re almost done, so keep going! Now go ahead and click on the Let me pick from a list of device drivers on my computer button at the bottom.
Now you want to choose a different driver for the graphics card. You might have play around and pick a different ones and see which works for you, but the safest will always be Microsoft Basic Display Adapter.
Depending on your system, you may see several drivers listed in the box, even the same driver listed multiple times. You can try some of the other ones, but if nothing works, just use the basic driver. Unfortunately, you won’t be able to run the OS at the highest resolution or frame rate if you use the basic driver, but at least you can adjust the brightness.
In my case, I simply switched to the basic driver, adjusted the brightness to where I needed it and then switched back to the original manufacturer driver. The brightness level remained at the level I had set it, so that was good. Then just check every so often to see if there is a new driver and install that when it becomes available.
However, sometimes an older driver works better. I had the same issue on a Lenovo IdeaPad P400 and I had to install an older driver in order to make the screen brighter. Otherwise, the screen was always dim, even with the brightness turned all the way up.
If you’re still having trouble adjusting the brightness on your Windows 10 machine, post a comment here and let us know the details. Enjoy!
Hi guys,
I'm using a Samsung ATIV book 7, it's brand new, but I'm having problems with adjusting the screen brightness. Neither the key controls, nor tampering with any Control Panel settings make any difference. It set itself to a relatively low level and won't react to anything.
It has an Intel HD400 in it and a Radeon 8500M HD.
My battery is fine, so the screen birghtness isn't set/locked due to some super-low power state.
I have searched far and wide for a solution - apparently I'm not alone with this problem, people with all kinds of laptops have run into it. Barely any solutions though.
I found a suggestion here:
http://windowsforum.com/threads/cant-adjust-display-brightness.5924/
I'll copy the main post here for convenience:
Anyone still unable to solve the problem try the following:
Start > Control Panel > Hardware and Sound > Device Manager
Once the Device Manger box opens expand the 'Monitors' tab
Left Click and Uninstall the monitor listed
Then select the Scan for Hardware Changes Icon
Sounds bizarre, but the adjust display brightness should reappear.
Now, my question is, does this sound like a good idea? What happens when I uninstall the monitor - will I still be able to see anything? (Sorry if this is a dumb question). Would you recommend trying the suggested solution above?
I'm cautious, as I don't want to mess up my brand new laptop.. But I also don't want to return the whole thing right away if this brightness issue is something that can be solved with a few clicks.
Thanks!
