Windows 10: Windows brightness stuck at 100%

I updated my laptop 3 days ago and now my brightness is stuck. I tried changing it from the battery settings but the option has vanished from everywhere. Then I tried uninstalling the display drives NVIDIA 940M and still nothing after following the procedure from this website. And I can't do anything now.

Brightness Stuck at Either 100% or 0% in Windows 10.

This issue
has been posted about before. I am having the same issue, but have noticed that my brightness is stuck at 100% or 0%. It seems to stay wherever it was set when it rebooted. I am about to see if it stays at 50%

I have tried:

• reinstalling (deleting the driver files) the video driver.
• Setting the brightness to 0 & rebooting

 

Screen Stuck at 100% Brightness

I recently bought a Lenovo ideapad 330 that came with Windows 10. Everything worked fine for the first two weeks until my screen is stuck at 100% brightness. I've looked around for a fix, and the one solution that everyone says should work (refreshing/updating
my driver) hasn't helped. So either I'm doing it wrong or the problem is elsewhere. It's killing my eyes and battery, so I would love for some help here

 

Brightness Control not working in Windows 10

Hi Ella,

To adjust the brightness, see the steps below:

• Go back to Power Options, and tick on the High performance.
• See if you can adjust the brightness.

If this not work, we highly suggest that you create an Administrator account, and re-do the steps above.

Let us know how it goes.
