Hi,

on Ubuntu 14.04 according to this thread:

* http://askubuntu.com/questions/125367/enabling-mic-mute-button-and-
light-on-lenovo-thinkpads

I cannot see
/sys/devices/platform/thinkpad_acpi/leds/tpacpi::micmute/brightness as a
link in /sys/devices/platform/thinkpad_acpi/leds:

 # ls /sys/devices/platform/thinkpad_acpi/leds/tpacpi\:\: [TAB]
 tpacpi::power/        tpacpi::standby/      tpacpi::thinklight/   tpacpi::thinkvantage/

Also acpi_listen does not give any value, when pressing the mic button.

Title:
  MicMute key on lenovo w510 thinkpad doesn't work

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Starting with linux-kernel 3.11.0-17 (linux-image-
  extra-3.11.0-17-generic), on a Lenovo ThinkPad W510 the LED within the
  MicMute key is working in the way that it is on by default (meaning
  mic is 'mute'/off). It turns off when activating the microphone via
  'settings'/Internal Microphone 'on' and lights up again when the mic
  is turned off, correctly.

  But the key itself (MicMute, KEY_MICMUTE) isn't showing any function; especially it is not turning the microphone on or off.
  The change apparently comes form the thinkpad_acpi kernel module. It seems, that the MicMute-key press/release isn't registered at all, as I couldn't successfully detect an acpi key 'event'.

  This is for notification, mainly, but thanks for any activity to
  repair that behaviour.
