[Bug 1431002] [NEW] Brightness Issue
Public bug reported:
I cannot figure out how to change the brightness for my Lenovo Y-510P
laptop. 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.
