HI,
I think, you cannot control the power LED of BBB, it would give the PMIC status.
You can control the user LEDs.
Why do you want to control that power LED ?

If you see any blinks from power LED then refer to the following link.

To know how much power LED is really consuming, its a part of power management.
Thank you for your reply,
