My MacBook Pro 2012 mid 13” will not boot up. It keeps trying, the fan runs for a sec and the indicator light turns on, but almost immediately it shuts back down. I believe I’ve found a missing ferrite bead but cannot find the part number to replace it. Does anyone have a schematic to find this part?
Es esta una buena pregunta?

Kaleb Williams looks like this board is a 820-3115 and the missing component is actually NOT a ferrite bead. It is reference designator R1982 which is a 10K ohm 5% 1/20W resistor in a 0201 package.

Cheers for that mate, also would you know what condition the computer would be in without that resistor. Just hoping this is the reason my Mac won’t boot
Kaleb Williams it could be related to your MBP not turning on. Of course, you do want to replace the resistor. It is part of the PCH DMI/FDI/PM/Graphics circuitry, in particular the GPIO29 rail which comes of U1800 system power management and connects SLP_LAN to ground
