Green LED under left speaker grille
Hello,
I noticed there is a tiny green LED that is visible under the left speaker grille on my MacBook Pro 17".
It is not visible from directly above, but is quite visible from normal typing position in an office.
The light shines from a single hole in the left speaker grille (the array of perforation holes from which the sound comes) next to the keyboard.
The hole is in row 4 from the front (front means the part of the Mac closest to me when typing) and column 15 from the right. I am average height and it comes into view and disappears if I move my head forward toward the Mac and back within a range of 10cm.
It is not the caps lock light, rather it is a very tiny bright green LED. It isn't ugly, though it does distract my eye.
Perhaps it is a RAM logic related light, or something related to the microphone, the ambient light sensor. What is it, and can it be turned on and off?
