Habe den Akku (Fixit) getauscht, alles bestens, genau nach Fixit Anleitung. Gerät angeschaltet, Akku geladen, alles bestens, dann wieder ausgeschaltet - nichts geht mehr. Alle möglichen Tasten Kombinationen versucht, mit, oder ohne Ladegerät. Der Laptop startet nicht mehr. Hilfe !
Please find attached a photo of the Bord
Pls find attached a close up
Ist dies eine gute Frage?

Hallo @pinovonkienlin
hast Du das Macbook mal aufgemacht und geschaut, ob der Akkustecker noch sauber in der Buchse sitzt? Vielleicht ist er nur rausgerutscht.
War diese Antwort hilfreich?
OK, danke für den Tipp, prüfe ich nochmals. Optisch sah er zunächst gut aus. Ich werde ihn einfach nochmal aus- und einstecken.
Habe gerade alle Stecker neu geprüft und neu verbunden. Es hilft leider nicht, der Laptop startet nicht.
@pinovonkienlin what happens when you disconnect the battery? Does it start without it? Any change in the computers behavior
Translation
Was passiert, wenn du die Batterie abklemmst? Started er ohne sie an? Ändert sich das Verhalten des Computers?
I did disconnect the battery and the Computer does not start. So seems to have nothing to do with the battery. Anything else I can do to check, or reactivate the computer?
From the Fixit Guide - I did: sudo nvram AutoBoot=%00, before I removed the battery and I did: sudo nvram AutoBoot=%03, after I positioned the new battery. This might have caused something?

@pinovonkienlin First, check the fuse F7000 for continuity. Then check it for power. For that, be careful with your probe ends (don't want to shorten anything out) since your system must be plugged in. Black on ground and red on one, then the other, contact. Let us know what you get.
If you are unsure about which component I marked, post a close-up of that area with your Question.
@pinovonkienlin the fuse looks good, but looks can be deceiving ;-). Time to measure it for continuity.

btw. I've ordered an Ammeter, needed one anyway :-)

@pinovonkienlin awesome! That will show us if your logicboard is even drawing anything. Of course you need to try all your ports. I am sure you have tried to charge on multiple ports already.

@oldturkey03 , I've checked the fuse, which looks ok, normal through put. Yes, Ive checked charging with all ports, no change.

@pinovonkienlin I guess we are still waiting on the Ammeter. I suspect this to be a controller IC issue and if your meter will show voltages in the 5V range and low amps, we would need to check PP3V3_G3H and see if you have power on there. Any chance you can get a larger image of your board posted? That way I could outline the components to be checked...
