MacBook Pro 2009 C7771 Capacitor

[Roman78]

Lately I'm experimenting whit some Macbook Pro's. Now i read the 2008 and 2009 have some issues whit the C7771 capacitor, like the 2010 has. So after fixing some 2010 i bought accidentally a 2009 told it was a 2010. Now it is a 820-2523-B. Now i locked up the C7771 but that is a very small one.

I found the schematics of the board, but those are for the 820-2523 (without the B).

This looks similar to the 2010.

But according to the openboardview it should be this one:

Is this the right one? It seems so small. Or was this fixed whit the B version, or is it another Capacitor?

This is a ceramic cap. Why are you replacing it? What do you mean by “experimenting”?

By the way, that is a bypass cap, used to filter voltage spikes on the line. As an electrical engineer, I see no reason to experiment with bypass caps. They are good or they are failed... no experimenting necessary.

On several Sites and Youtube videos they are telling about the C9560 on the 2010 boards and C7771 on the 2008 and 2009 Model. But this one is different. Also it is not a Tantal and not 330µf, only 22µF.

By experimenting i mean, that i buy defective MBP and try to fix those.
