MacBook Pro 13'' Cant find battery, replacement doesnt work too
After not using the macbook for 6 months I opened it up and it didnt recognize the battery. I couldnt even put the symbol in the taskbar, it appears for a second but then dissapears. I tried to different replacement batteries but the system doesnt recognize them. All three batteries have been recognized by an other MBP. When I connect the the magsafe its light green and the statusbar at the side lights up BUT the third dot. I tried charging over hours but nothing happend only the third light is shining all the time. I tried the solution from this post -> 'https://de.ifixit.com/Antworten/Ansehen/...
Is there a way to see if the batterieport on the logicboard is working?
I tried SnowLeopard, El Capitan, HighSierra and even Catalina. Changed RAM to be sure that isnt the problem and tried another charger.
This is the screen off the menu
Is this a good question?
