How to replace damaged section on a Laptop motherboard

[naveen052]

Hi I had an HCL Laptop lying around which is been dead for two year and out of curiosity i tried finding out what's wrong with the laptop because when it was damaged, it was because of changed polarity of the laptop charger and i saw a little smoke coming out of the fan vents. Its been dead since then i didn't even get it looked at.
So yesterday when i dissected the whole laptop turns out that there was this section near the I/O IC that's been damaged i don't know anything about electronics nor i have a footprint of the mother board so
I was hoping someone could tell me what this section is called and how to replace this lets say at home.

You're not going to be able to replace that by itself. You need to replace the whole motherboard.

There is no way that an individual can replace this damaged component. Even a professional company with the appropriate facilities to deal with surface-mounted components would probably just bin the circuit board. You need a new motherboard; in truth it would probably be cheaper to just buy a new laptop.
