Disabling Button Backlight for Battery Saving and Light Life

How?
1. Mount /system as Read and Write
2. Go To /sys/class/leds/button-backlight and change brightness and max_current to "1".
3. Go To /system/etc/hw_config and scroll down a bit. Now Change max_current to "1", too.
4. Reboot. Buttons Light will not light up anymore.

About the Attached File - just extract Disable/enable.zip to sys and than change hw_config.
For Disabling Just change hw_config ---> max_current to 455.
