Hi Guys,

i have attached pictures and schematics in-regards to the issue im having

Schematics

looking at things i should just be able to remove C5820 the damaged component and the Macbook will power on again

as its just there to provide extra power stability?

but there has to be a reason why its there

thanks for your input.

A part like this one should work out as a replacement:

Case T = 3528 tantalum code size with a height of 1.1mm. Low ESR rating to allow for higher current support.

The same power rail has a few caps marked with an 'X' so they will not be stuffed on the logic board. Confirm this detail. If the PCB pads are available, you can also consider to populate those with more of the same caps. Not sure if there are height restrictions due to any metal shields or casing issues so you will have to check before purchasing. A digital micrometer is a great tool to measure the dimensions of the original component before proceeding. The schematic lists as case 'B12' which appears to relate to tantalum code size 'B' with a height of 1.2mm.

I recommend u to change the capacitor from donor board as it is a critical component .
