Video showing the issue

I've an Asus N56VZ laptop with Intel Graphics as my GPU on it. I'm using i915
driver and the brightness can be controlled via
/sys/class/backlight/intel_backlight/brightness file.

When I use keyboard hotkeys to lower the brightness further than a level it
goes back and forth as it becomes close to zero, sometimes it completely shuts
down the screen and pressing down again restores it to some level. I'm
attaching a video which I'm continuously pressing Brightness Down button.
