Components missing in an area of ​​the board

Hello. I need help!

I made a post about a component that would be missing from my board after it undergoes oxidation.

A collaborator helped me by indicating the missing component, but when looking at the photo sent by him I realized that more components may be missing.

Again I ask for the help of the community!

The best way to figure things out is by snagging the boardview drawings and schematics. They can be found on the Internet! Do a Google search for the board number 802-2530 sometimes it takes a bit of searching Like this

To help to locate if the files are out in the wild I reference this board Logic.WiKi

Between the two you should be able to ID any component on the board!

The board is scorched by an overcurrent fire. The reason doesn't matter anymore - maybe a loose part having shorted the circuit. It should have been smellable.

You must replace the board. Look for a replacement board (eBay, iFixit etc.) and the procedure description in iFixit or elsewhere. I do this scores of times with a different MacBook, thus prolonging its life for eternities.

Good Luck!
