Windows 10: Volume and Brightness buttons sometimes requires and sometimes doesn't require Function key.

In order to change the brightness or volume with the keyboard buttons, I have to hold down the Function Fn key. The issue is that it randomly changes to not requiring the Fn key, and I can just press the volume or brightness buttons to adjust it. Every now and then it switches back to requiring the Fn key, and then back to not requiring the Fn key. Could it be every time I have to restart to finish updates?

Changing brightness is no longer smooth with function keys on 1903

Hi, There's a the slider for brightness at the bottom of the Action Centre (build 1903).

If you'd be prepared to consider an alternative... how about smooth control of brightness using your scroll wheel?
Press a key, plus scroll, and adjust your brightness.

The key and the steps are your choice.

Oh, and it can adjust volume similarly.

Works nicely on my Lenovo Thinkpad, where the Fn key steps for brightness are a bit harsh.

My function keys don't work

Some F buttons require the user to press the function key in order to get the specific F key to work. Often F keys have a dual role one for F function the other for changing volume, brightness, etc.

 

brightness key working but not performing the required function

Hello,

I have an HP Ultrabook 820 G3. Its brightness keys are located at F5 and F6 but both are working but not performing their brightness increase/decrease functions. At the home page, the brightness keys scroll through the apps located at the taskbar but do
not increase or decrease brightness. Please tell me how to fix this. Thank you.
