Oh, I see, I'm not alone with that kind of problem. I own a T400s with maverick currently installed. The mute and micro buttons don't work in the right manner. I don't need the micro button so I've informed the makers of the thinkpad kernel module about the problem. They answered that without an T400s it is difficult to analyze this behavior. But for the mute button I think it worked some versions before. As far as I know in 9.10 it worked like in Windows 7. In 10.10 and also 10.04 the mute button toggles off the sound but not the system beeps. This is the really annoying thing and therefore the buttons LED doesn't switched on. Only if the LED is on the sound is really muted (also system beeps) and this is what I want. I have colleague who owns a T510 and I've seen that at least the mute LED does work on his laptop in opposite to some posters before. Both laptops (T400s and T510) are using the same keyboard layout. I can't see a reason why the behavior is so different.
