i have hp notebook 15 ac 119 tx
because of various errors after windows update i put my system on recovery after the recovery again the problems have started coming. recent problem is of brightness. i cannot adjust my brightness at all. F-keys from keyboard have no effect and even it can not be adjusted through control pannel.
i checked in device manager regarding the dispaly drivers update. it says i am using the latest versions of display drivers.

I'd try reinstalling the amd/intel switchable graphics software package on the link below as it mentions a fix related to the f2/f3 keys.
When this has completed, restart the notebook.
