My Minibook X n150 backlit keyboard is purple not white

How can I turn it to white? when I first turned on the backlit keyboard.. It was already purple not white.. please help

I uploaded a video for reference, I think it is noticeable here in the video that the backlit keyboard is purple and not white. Personally, it is very much noticeable that it is purple and not white,

I dont like the purple color very much…

I searched why this happens, It says there might be defective LEDs or wiring fault on my minibook x n150… huhuhuhu :sob: :sob: :sob:
another is firmware/BIOS glitch.

I hope its only a firmware/BIOS glitch..

can someone help me?
