Gigabyte GA-H61MA-D2V Help

Hi, I recently started to build a system and notice a small burn mark on the board.
I still manage to install os and boot the system but wondering if anyone can sched some light on the burnt bit of the board.
What does it control if any? and what is affected?

Look at big red circle and arrow

I think it's ok, sometimes, there is some stain left on the motherboard, it's from the manufacture process. totally normal
