Freebook 360: can I get keyboard backlight turned on after turn the laptop on?

I really like backlighted keyboard of Freebook 360 but Im searching for a way to keep it turned on when I turn my laptop on. At the moment I have to turn the backlight by pressing key combination Ctrl+F5 every time I turn the laptop on, I can’t say it’s really convenient.
Maybe I missed something in BIOS settings? Tried to search across settings I have but there are so many features…
