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.
