If it is the black chip in the very middle it clearly has a serial number that is illegible because of the poor picture quality. Take the number and google it and you will have your answer.
The function on the motherboard maybe are part of main power regulation or battery charging system, didn't check the datasheet of this motherboard, but a chip of 30v on a laptop only can be for these things.
Check any short on this line before replace it and the stability of the power supply, something should cause it burn like that.
