HP 15t Cannot turn off autobrightness

[Cgreen223]

My screen keeps auto adjusting the brightness while I am photo editing, but the brightness percentage is staying the same.  I have tried going under the power management advanced settings, but there is no option to enable or disable the auto adjust.  There is also no graphic icon under the control panel.  Help!
