This is a known issue with Lenovo Thinkpads. The workaround is to use a
shell script and a recompiled kernel module. You can find the steps
here:

light-on-lenovo-thinkpads

It would be nice if this could work out of the box, though.

Title:
  [Thinkpad T410s] Mute indicator gets out of sync

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The Thinkpad T410s has an indicator led on the mute button and one on
  the microphone mute button.

  If I only use the hardware mute key everything works fine, but when I
  use indicator-sound or pavucontrol the LED won't switch off and the
  indicator gets out of sync.

  Mute in /proc/acpi/ibm/volume follows the hardware key and also
  doesn't switch when I use pavucotrol or indicator-sound.
