 +===== Using side LEDs and WiFi LED =====
 +(This is for the 12.04 kernel)
 +The LEDs on the side can be triggered by echoing values between 0 and 7 to
 +  echo 7 > /sys/devices/platform/nvec.0/nvec-leds.0/leds/nvec-led/brightness
 +for different blinking-patterns (need to be root). Try
 +  echo 0 > brightness ; sleep 1 ; echo 7 > brightness ; sleep .2;echo 1 > brightness
 +to 'allways-on' the side LEDs
 +
 +You can also set different triggers for the WiFi LED. To see the available options do
 +  cat /sys/devices/platform/nvec.0/leds-gpio/leds/wifi-led/trigger
 +then to change the trigger (temporarily) do for example
 +  echo mmc0 > /sys/devices/platform/nvec.0/leds-gpio/leds/wifi-led/trigger
 +to get eMMC activity.
