Brightness control , sleep and battery icon not working on macOS HS installed on hp pavilion15 ab237ne laptop

Hi, recently, i was able to install macOS high sierra on my laptop. almost everything works except these :

sleep issues : when macOS goes to sleep , i cannot wake it up no matter what i do. it just turns on the screen when i press a key. no picture.

brightness control: it doesnt work. 100% at all times

battery icon: this may not be that important but the system does not see the battery at all, it thinks it has 0 % charge

info about this laptop:

cpu : intel core i7 6500u

gpu : intel hd 520 + nvidia geforce 940m (i disabled nvidia with this flag : -wegnoegpu because nv_disable=1 didnt do it)

chipset : intel series 100

ram : 8 gb sk hynix ddr3

config.plist that i used : rehabman's intel hd 520 series config plist

what can i do to solve those issues? im a novice and i dont have programming background so please explain in detail. if more info is required, say so.
