I have recently bought a Dell XPS 15z and I have found that the ambient light is not functioning properly, I mean when I am pressing the fn f6 then I am able to control the ambient light properly but then I have found that when I am using the laptop in the in a room with "full light" or sunlight then the keyboard light will turn on, I donít think that it is normal?? And it does not light up when I am in a fully lit room. The other thing that I wanted to share is that when I am setting the fn f6 key to medium then it stays like that the next time as well, I donít know why the it is not remembering the last setting. Is there anyone who can help me out with the same?? Any help regarding the same will be appreciated.
