    I have a hp 15 ac-083tx laptop running on windows 8.1. few days ago my brightness controller stopped responding, even on changing the power options the brightness doesn't change. Once i had updated few of my drivers including the graphics and other like bios synaptics etc. The brightness control started responding. But after few days again its not responding. I have updated all my drivers but its no use.
    Please help
