[Bug 1125452] Re: [Lenovo T530]: Volume Mute key LED is not responding correctly


Jeff Marcom, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (2.57). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

  Problem description:

  When attempting a hardware mute the volume mute action is applied
  correctly and the volume applet correctly displays that the audio
  output is muted. However, the mute key's LED backlight's
  responsiveness is flaky at best. Pressing the mute key repeatedly may
  or may not result in an mute key LED change. This can quickly get out
  of sync where it's possible for the mute key LED to be lit yet the
  volume is not actually muted.

  Again mute action does actually respond correctly via keypress:

  Software mute does not change status of LED.
