I got an A1398 2.8GhZ, 16GB, mid 2014, OSX 10.15.7 with bad Akku
After replacing it came back because it shows by clicking on battery symbol "service needed..."
I replaced the accu checked, no service symbol and sent back
Now i got again with the same problem (1 day later)
I dont had password from client and tryed my SSD, no service needed, tryed with an external empty drive new installed catalina, -> no batterie service needed
I tryed to install "over" the client installation, same problem
tryed update with big sur on the client installation, same problem
ofcourse SMC and PRAM Reset already tryed
did anybody had this problem before? need help please
