Windows 10: Brightness buttons stopped working Win10

Hello. I have an HP Laptop (HP EliteBook 840 G5) running win10 enterprise. My Fn f3-f4 of the brightness control stopped working after an update.

when my computer was new i had this issue, and after a lot of error and trial it appeared i needed an Intel driver of chipset management.

since the last update it's not working again.

I tried to:

1. uninstall and re-install the chipset driver that solved it last time.

2. roll back the screen adaptor driver

3. to look for update of the adaptor's drivers


all of the above didn't solve this problem. is there another solution I haven't tried yet?

:)
