The Ubuntu 3.11.0-12-generic kernel shows the following leds on the T410

LED path physical location works?
/sys/class/leds/mmc0::/ unknown unknown
/sys/class/leds/phy0-led/ wifi led below screen partly, can be only be turned on permanently
/sys/class/leds/tpacpi::power/ under powerbutton yes, can be turned on and off
/sys/class/leds/tpacpi::thinklight/ white led above screen yes, can be turned on and off
/sys/class/leds/tpacpi::thinkvantage/ unknown unknown
/sys/class/leds/tpacpi::standby/ on the lid next to the battery led yes, can be turned on and off

Example to turn a led on:

echo 1 > /sys/class/leds/tpacpi\:\:thinklight/brightness

and off:

echo 0 > /sys/class/leds/tpacpi\:\:thinklight/brightness

Furthermore, with this kernel, the LED on the mute sound button works, but the led on the mute microphone button does not.
