Windows 10: I can't increase or decrease brigthness

Hello everyone!.

I've read a lot issues about this problem. In my case all Fn keys works but the keys related with increase/decrease brightness doesn't works. Also I tried change the brightness by ows options but the problem continues.

Here my pc details:

Samsung NC110
Intel Atom CPU N455 @1.66GHz (2 CPUs), ~1.7GHz
2048 RAM
Intel Graphic Media Accelerator 3150 - 256MB

The graphic driver installed in my pc is this:
Intel(R) Graphic Media Accelerator 3150 (Microsoft Corporation - WDDM 1.0)

Bye!.

:)

 

While I increase or decrease brightness, actually the glow level is not changing. How to solve this issue?

Okay, it seems like DISM Tool bounced back with an error 0x800f081f. This means that there is something corrupted on the System Files.

Hi Pritam,

Whenever you change a setting on your computer and it doesn't make any difference the way you have it set, it is possibly being caused by the driver of that specific Hardware (sounds, display, network connection, peripheral devices etc.). To further isolate
the possible cause of this issue, we need to ask you the following questions below:

• When did this issue started to happen? Is this a new computer and was it not working since the beginning?
  
• Have you done any updates or upgrades on your computer before this issue happened?
• Have you tried booting to Safe Mode and check if it is still the same?
• What troubleshooting steps have you done so far?

We are looking forward for your response.

 

Try to find the hotkey software specific for your system.

I had a laptop here were a few keys worked, but I couldn't lower or raise the sound with my keyboard. I installed the hotkey software specific for my system, a version that was around when Vista was introduced, and it fixed my problem.

 

Thanks for the answer!

I have installed the last version of Easy Display Manager. This software (offered by Samsung) allows the keyboard functions but the last version is for ows 7 and doesn't change the brightness. All another Fn keys works.

 

I just noticed that you also mentioned that you tried to change it with Windows options. Then I think it's a issue with the driver of you graphics card. You probably will need to wait for a fix from the manufacturer.

 

Yes, I think the same thing than you.

Thank Rudy!.

 

There is another thread floating about this, in my case i am running a win7-8 driver for a Radeon 6370M. That is the only way I got brightness to work.
Try an earlier driver, or whatever driver you had working before.
