Re: apple macbook a1398 15" retina (820-00426-A)
Use 820-00163 boardview, 820-00426 boardview is not available. Only the Q7180 area is different I think.
Also the schematics you attached is for 820-3332, completely different board. Again, use 820-00163 schematics, the 820-00426 schematics is available but only the first page is different from 820-00163 so it is useless (although, again, Q7180 is not the same on both boards).Comment

by fishaHallo everyone, my A1398 do not charging the battery and the battery also do not bin recognized. I did all the reset work, SMC reset and all the other reset options but nothing helped. on the SMC at pin 2 (DCIN) there are 20,4V coming in. at pin 16 (BGATE) which goes to the Q7155 Gate there are only 11,43V. at the pin 1,2 and 3 on the Q7155 (Source) there are 12,23V. Cap C7126 is not shorted. As I understand, the gate voltege have to by higher then the source voltege for the gate to clous so the battery can be charging, am I right? can someone help me with this? I guess that manny models are working...
