Windows 10: Brightness control witn FN buttons on samsung galaxy book3

Hello! My laptop is samsung galaxy book3 NP754XFG btw in settings -> about system wrote that it is 750XFG, what's the difference and why? on windows 11. As I remember my problem began after win update to 24H2. So the problem itself is that when i press FN buttons to control screen brightness it works pretty strange. Brightness not but an icon of it "sun" is moving. I would pin screenshots with difference. Thanks for help!Real brightness is not changedanyway I availiable to control it in this menu.

Brightness control option using the keys "fn + f9" and "fn + f10 are not working on Windows 10.

Original Title: Windows 10 brightness issue

I have an HP ProBook 445 G2 Notebook PC that came with Windows 8.1 Enterprise. I recently did a clean installation of Windows 10 Home. My keyboard had a brightness control option using the keys "fn + f9" and "fn + f10". These brightness control hotkeys stopped
working after I installed Windows 10, although other hotkeys like the one for volume control still work. The brightness button in the action center cycles only through steps pf 25%, which is sometimes inconvenient. How can I fix this?

 

No brightness control for my Samsung Series 7 Ultra (NP740U3E)

Yes it was bought in Septemeber 2013, and yes it was Windows 8.I have replaced the hard disk and re-installed Windows 10 from scratch to put in a larger SSD.
Brightness control is on Fn/F2 and Fn/F3. It was working until maybe a week or two ago. In Windows10 Settings ==> Display ==> "Change the brightness for the built-in display" This can be changed either with the slider on the screen OR Fn/F2 and Fn/F3... which also move the slider!So the function keys still work but the signals are not getting through to the graphics card.Should I risk installing older drivers? (e.g. Windows 8?!)Either way, I just managed to download SWM_Setup.exe (which extracts into the directory: "SWUpdate_2.1.14.1") But when I tried to run it (as an Administrator) I got a nasty popup window called "User Account Control",that said "An Administrator has block you from running this app"





What to do next?

EDIT: Wait, maybe it is trying to install Samsung Update - something which I already have installed. I just tried uninstalling Samsung Update but it still won't let me install "SWM_setup.exe" it. I uninstalled Samsung Update but I think your zip file is a Window 8 version. There was a Window10 version of Samsung Update on the products web page so I tried re-installing that. This time it ran after a long pause it said "This model can be supported through a Windows Update"

However when I try to run Windows Update it says "Error Encountered" and suggests that I run one of Troubleshoot programs. I have run various of the Troubleshooters, but there doesn't seem to be one for the display adapter... :^(
