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.
Seems a dual channel 30v transistor:

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.

Now I could go with soldering the contacts from the cable to the connector on the mobo, but doesn't sound like a good permanent solution. -

Man, that's beyond my brain
I'm no good with hardware for now. I'd like to get into hardmods in future though -

@Maximumbeans, Maybe start practice soldering. Get a cheap-ass soldering iron and follow some good YouTube tutorials.+1

Least my experience has gotten better than over a decade ago. My iron would constantly bump into components and break them.

Sounds good. I actually did soldering but like 16 years ago for school so uuuuh probably rusty haha

@Maximumbeans, Same here. I did soldering at school from a teacher who I honestly liked since he had plenty of good electronics experience.+1
