In this thread I'll show you how to disable the button backlight on your Xperia device.

Step-by-step:
1. Mount /system as read and write, i.e. RW
2. Go To /sys/class/leds/button-backlight and change max_current to "1".
3. Go To /system/etc/hw_config and scroll down a bit. Now change max_current to "1".
4. Reboot. Buttons Light will not light up anymore.

I made a script. Check it out! http://forum.xda-developers.com/show....php?t=2342987
