I have an Asus vivobook x510uf laptop. anyway, I replaced my laptop keyboard with a brand new blacklight keyboard. but it doesn't work. I tried all bios and atk driver updates. I double-checked if there is a loose connection on my motherboard blacklight keyboard power port. all keyboard keys are working fine. but the only blacklight on-off keys are not working, I don't know what the reason is, I'm tired of finding solutions to this. plz help me with this
