Windows 10: can't change brightness with fn key

Hi,i have an old dell latitude e6420 and i recently installed windows 10 on it and updated it, and i cannot change the brightness using fn+arrow keys, yeah i can usee the notification panel to adjust brighness its working but the fn+arrow keys is a better way for me, it works in the BIOS and it also starts working when i restart the windows once and other wise the fn key works everywhere, but not with brightness keys the only way to get it working is to restart the pc or enter BIOS.

Brightness and Fn keys

Greetings,

On a previous computer, if I wanted to decrease brightness, I would press the F7 key. If I wanted to search, I would press Fn+F3. On my present computer, I have to use Fn+F7 to decrease brightness, and F3 alone searches. How do I reverse the Fn key requirement
to not needing it for changing brightness, sound, etc?

 

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.
