For those who haven not figured out how to play with the LED subsystem yet....

cd /sys/class/leds/
Then for example cd input0\:\:scrolllock or any other device
cat trigger
Look at all the possible triggers , choose one ... for example....
echo disk-activity > trigger

and watch your scrolllock LED magically flash at at disk activity

by the way... if anyone have some RGB LED status light or perhaps a "traffic light" type status light that works out of the box with this interface I would appreciate to hear about it - looking for something simple I can use as a status light for some of my servers.
