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. >From tlp-stat (tlp 0.6): --------------------------------------------- +++ System Info System = LENOVO ThinkPad W510 4391E46 BIOS = 6NET84WW (1.45 ) Release = Ubuntu 14.04.1 LTS Kernel = 3.13.0-39-generic x86_64 /proc/cmdline = BOOT_IMAGE=/vmlinuz-3.13.0-39-generic root=/dev/mapper/madagaskar--vg-root ro quiet splash Greets Axel -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1288726 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.
