Which are components of power circuit?
Hi, I hope you will be able to help me out in this difficult request ...
I am looking for a photo , a guide , a scheme anything that is specifically the power circuit of a MacBook Pro Unibody 13 ' ' Early 2011
The problem is that the Mac can not charging the battery ... after several readings and tests think is a defect caused by some faulty components on the logic board ....
If I could go back to the components that are part of the circuit power could more easily identify the faulty one ....
Thank you of attention , I look asia answers .
Is this a good question?

Disclaimer in advance so this doesn't get branded as noise: you are going to have to do some independent research to figure out what current sensing is, finding schematics, etc. I will help but not spoonfeed. I cannot dump six pages of information into every board post, it would make it impossible to have the time to make these, so feel free to do some self-learning & homework based on my questions which will lead you in the right direction.
1) Does it see the battery but refuse to charge it? Or do you just get an X?
2) Does it work off of the charger when the battery is not plugged in?
3) Have you tried a different battery already?
4) Have you checked R7050, R7051, R7052 & the traces between each of them and the ISL6259(U7000)?
5) Have you checked the trace between U7000's CHGR_BGATE pin and Q7055?
Come back with some answers so we can narrow down to your specific problem.

no because I do not know how to test these components and do not know their position on the motherboard, I would help a lot with a photo shows the components to be tested

Find a schematic and a boardview and you'll find all these points.
