Hello,

My laptop has light sensor and I installed windows11 pro(10.0.22000), I select the option "Automatically adjust brightness when light changes" on the system/display panel.

I found that the brightness bar can not slide to less than 55%, that was the minmum brigthness is 55% when the ambient light was every dim, but windows10 has no this issue on my laptop.

Is that windows11 bug? Can anyone help me?

thanks a lot!

    Hi there,

    Their is no details on the bug report for this behavior. Windows 11 known issues and notifications

    A driver update is the first thing you should do regardless of what device you’re using. Many Windows users reported that doing this fixed their issues with the brightness not adjusting. Go to Control Panel > System and Security > Power Options and check that your power options aren't affecting the brightness on your screen.

    Update drivers manually in Windows https://support.microsoft.com/en-us/windows/update-drivers-manually-in-windows-ec62f46c-ff14-c91d-eead-d7126dc1f7b6

    You can also try the SFC & DISM scan . Use the System File Checker tool to repair missing or corrupted system files https://support.microsoft.com/en-us/topic/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system-files-79aa86cb-ca52-166a-92a3-966e85d4094e
