The LED in question is located right next to the charge LED(marked Chgled) and is just called LED on the board and System LED on the expansion connector pin out sheet.

No LED that i can see. I suppose you mean the (unused) PINs at the very bottom.

Yes, the software programmable and charge LEDs are optional  and are not installed on the board. When my board arrives, I plan on wiring up the LEDs and the power and reset switches.
