Dears Friends, first I have to say sorry for my bad english, I will do my best. I got Macbook A1342, no power on with and withouth Battery (I charged it with another MBP). If plug the magsafe connector the led will light really dimm, somethime green and somethime green and orange. If I plug the magsafe and battery at the same time than no led on magsafe. The Magsafe Board isn't, I tryed with anotherone and i got the same symptome. I suspect the problem can be a bad capacitor or transistor? I have schematic and board view for this model but how can I test the capacitor? Or may be the reasons of this problem is completly different? Thank you a lot in advance for your help! Great Regards!
