I go to brightness settings and it will not let me change the brightness at all and defaults to the brightest setting and drains my battery. I also have specific keys to change the brightness which also will not work. Any help would be greatly appreciated. I am not much of a computer programmer so I am not very savvy so any help would be greatly appreciated.
