Hello everyone, I have a little problem.

the brightness keys aren't working for some strange reason.

I've tried installing the hotkeys driver for my case it's the sp140913, but the brightness keys still don't work.

the volume keys are working fine however, and I'm sure the f5 and f6 keys responsible for the brightness are working just fine. Everything else is installed, I made sure all the drivers are up to date but to no avail.

I suspect that this driver sp140913 didn't install correctly. I've searched the internet on how to reinstall it, but I didn't find anything. I think it has to do with something called "fusion" but I don't know much about it.

I hope someone has the solution to my problem.

Thanks in advance
