Alienware Light middle Dim

my "Alienware" Wording lighting is dim on my m17x r4 not bright like on my m18x, i've had 3 screen replacements and it is still glowing dim what do i need to ask for to fix this issue is the cables faulty or is it motherboard not supplying enough current so faulty mobo any help is appreciated : <

 

You havent got the dim lighting zones enables have you? and i would sya my alienware logo is on par brightness with the keyboard and my trackpad is the brightest by far. Maybe loose connection? Is it still a linear brightness across the sign? might be better to take a photo i guess.

 

i can't be bothered taking the laptop apart atm since it has warranty and scheduled for a motherboard replacement soon this week hopefully or next week monday depending on when the parts arrive. The blue on my alienware wording seems like a navy blue dark glow not a bright glow like on my m18x here are examples http://i594.photobucket.com/albums/tt27/mooshiebu/IMG_0049.jpg and this is how it should look Google Image Result for http://www.3cbang.com/upimg/2012/6/111929_1843432737.jpg

and yes dim lighting zones is unchecked in the alien fx

Update got mobo replaced today ,still the same issue how can I resolve this

 

Have you seen any other m17x? It is probably different.
