 ===== Lid and jack insertion events =====
 You can use a lightweight https://github.com/gandro/input-event-daemon, it should listen on ''/dev/input/event4'' for ''LID:0'' and ''LID:1'' events.
+===== 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.
 ===== Video playback =====
