Windows 10: Windows 10: Brightness Options Missing?

Hi all,

I was wondering if someone would be able to help me out with an issue I am facing with the brightness options in Windows 10 Pro. I've owned this laptop for around 5 months now, and I've always been able to change the brightness on it as and when i please using either the function keys, or settings in battery menu or control panel display settings. All of a sudden after updating my PC to the Fall Creators Update (1709) when it was first released, I am no longer able to do this, along with options missing from the Windows Mobility Center. The option for brightness control is no longer in the Action Center, and I cannot enable/disable Night Light. Any search that I do within Windows for "Brightness" only brings up options for the visually impaired and so on. Furthermore, "Display" has disappeared from the control panel, but this could be due to the migration to the settings menu.

I wouldn't be too bothered about the screen brightness if it didn't have such an effect on my battery!

I've attached some screenshots to help explain.

Thanks.

Unable to change screen brightness using both my keyboard options or settings/display/Brightness and Color Settings.

I have a Dell Inspiron 5577 with a i7 processor and windows 10 home edition 1709. Recently I believe due to a upgrade in windows am not able to manually readjust my screen brightness settings with both my keyboard options or Settings/Display/Brightness
and Color options. What must I do to enable my ability to manually adjust my screen brightness settings with both my keyboard options or Settings/Display/Brightness and Color options?

 

Unable to asjust brightness windows 10

no matter what I do I am unable to adjust the brightness in my settings as the "adjust brightness" bar as shown in http://windows.microsoft.com/en-gb/windows-10/change-screen-brightness. I have tried to fix this by:

• rolled back drives
• updated drivers
• disabled drivers
• reinstalled drivers
• updated windows 10
• restarted computer
• completely turned computer off and on
• enabled adaptive brightness in power options
• disabled adaptive brightness in power options

None of the actions above has changed anything. How do I see the "adjust brightness" bar?

 

You can try using this, it is in the control panel

 

Unfortunately it won't work!

 

Maybe you should run sfc /scannow from an elevated cmd prompt. Maybe that will help.

 

If you have not installed latest version of your laptop graphic card driver then download the latest graphic card drive from either your laptop manufacturer website or from graphic card manufacturer website.

Have you check the Control Panel --> Power Options applet at the bottom of Power Options applet there should be slider for setting screen brightness.

 

What laptop do you have? You might be missing a power management driver. 1709 is incompatible with most.

 

I can't currently run sfc as it needs to reboot to complete a repair first apparently. I can't currently reboot the laptop until at least later tonight unfortunately.

The latest version of graphics drivers are installed (Intel HD Graphics 520) and the laptop is a Dell Inspiron 13 5368. All drivers are installed from Dell's website, along with a scan run with Driver Booster which returns that all drivers are up to date.

I've worked with Windows for years and I'm completely stumped.

 

You can try previous version of the graphic card driver maybe latest version is buggy.

 

I've installed an older version of the graphics driver with no difference made, problem is with not being able to reboot I can't see if these changes are making a difference. Having said that, the problem has been there for the last few months during daily shut down/reboots.

 

You will need to reboot to see issue resolved, reboot when you can and please tell us the result.

 

I will be doing later on. I'll let you know if there is any change.

I've also installed Dell QuickSet which was not previously installed, which has given me some power management options including "extended battery life" which I have now turned off to see if it gives me more options. I'm wondering if the tool disables particular options in order to try and get the best performance/battery life balance?

Not sure, I'll let you know when I find out more.

 

I don't think that utility cause the problem you can always restore default setting to see issue resolves.

If you haven't then please Open the Control Panel for Intel Graphics and try to change the screen brightness from Intel Graphics Control Panel.

 

I can modify the brightness there, but that is more the brightness of what is on the screen, not the screen itself.. if I change the brightness there everything becomes very dark or overexposed.
