The Lenovo Z560 Ideapad has a row of 4 led buttons in the top right corner of the keyboard. The button on the left end of this group is the speaker mute/unmute button. Usually, this light is either on or off to indicate the sound being muted or unmuted. This is how it works while the laptop is plugged in to an electrical outlet.
However, when running on battery, the light remains off when the sound is muted, but it constantly blinks when the sound is unmuted. The blinking is somewhat distracting. Is there any way I can make the led behave the same way when running on battery as it does when plugged in? Any system file I can edit? All I want is for the light to always remain in either a constant on or constant off state. Blinking on and off gets distracting.
