I got a Apple MBP 13" here with a failure on the Power Rail. It is not charging the battery and not working on PSU. It only works on Battery. The PSU light is green or off. When i remove the battery the MBP goes out immediately.
I found those two topics:

I measured pin 17-18 and 27-28 on the U7000, those are 3.3 Ohm and 20 Ohm, Just like in the the first link. So i replaced the U7000 with one of a spare board but with no success. So in the first topic someone replaced the Q7030, how to i measure that thing? The diagram looks like the picture added.
In the second topic they are replacing a resistor going bad, but mine ist still at 0 Ohm.
