MacBook Air logic board error, no boot & no charge?

Hello,

I have a first gen Macbook Air, it is not able to boot, and not able to charge.

The problem is not the charger, i have tried it charging with my MBP ac adapter and it didnt work also, not even the green light shined.

After removing the lower case, i saw that one component of the logic board is burned out.

I have added two pictures to show that part.

(not original ones, i have no cam)

This is written on the component 0806AJ

Logic board, Red marked component that is destroyed

Closer view of the destroeyd component

I am a student and cant effort a new logic board.

Can this problem be solved with just replacing the component that is destroyed?

And what is that component?

Thanks and greetings from austria

Niki
