Hello!

I upgraded my laptop over the weekend to Windows 10 1803. I noticed my display was set to max brightness. I am unable to use the F keys to lower the brightness. I am also unable to change the brightness in the display settings. My drivers are all updated. Any suggestions on how to fix this?

I have a Toshiba Satellite with the Intel (R) HD Graphics.

    Press Windows key + X

    Click Device Manager

    Expand Display adapters

    Right click the current display adapter

    Click Properties

    Click Driver tab

    Click Rollback driver if the option is available

    If not

    Right click the current display adapter

    Click Uninstall

    Check the box that says, "Delete the driver software for this device.”

    Exit Device Manager

    Restart

    Go to Start -> Settings -> Update & security, then Check for updates and install any available updates.

    Andre-

    Ok, I tried this. It installed the Microsoft Basic Display Adapter. I checked for updates and Windows Update claims my system is up-to-date.

    So now I have a basic display driver and I'm still unable to modulate the screen brightness. Any other ideas?
