Example to turn a led on:<br />
<pre>echo 1 > /sys/class/leds/tpacpi\:\:thinklight/brightness</pre><br />
and off:<br />
<pre>echo 0 > /sys/class/leds/tpacpi\:\:thinklight/brightness</pre><br />
<br />
Furthermore, with this kernel, the LED on the mute sound button works, but the led on the mute microphone button does not.<br />
