Sony Vaio Backlight

Hi,
I’m using Ubuntu in a Sony Vaio SVF15A17CLB, which has a backlighted keyboard, but it’s not turned on by the System by default, so, every time I want to turn it on I have to manually change the value in:
/sys/devices/platform/sony-laptop/kbd_backlight
from -1 to 1 with sudo vi

But that resets every time I restart the computer.

Is it a setting somewhere else handling that? Can I make it permanent?
