    Assuming you're talking about Windows, go into Power Options, Advanced Power Settings, Display, and make sure Adaptive Brightness is disabled.
     
    Stop hovering to collapse... Click to collapse... Hover to expand... Click to expand...

    this is a funny windows issue I tried another program to control brightness called Ibrightness tray, and it worked perfect.
