Is that really a good idea? When I mute the speaker using software, the
state of the LED doesn't change. After that, if I use the button, the
LED shows the opposite of the actual mute state.
(X220 here, but I'm assuming the same design.)
If you are good, you will be assigned all the work. If you are real
