Hello guys,
I have a macbook pro A1989 13" from 2018 with some issues, the most annoying issues. Sometimes it turns on and it works fine for just a short time but the time can vary between 5 min and 20 min (suddenly turn off), and in another time the macbook does not want to turn on at all, so there are 2 cases, both of them are unfavorable.
I tried to reset the SMC and PRAM without any succeed, I tried also the install the last updates, but it would not happened because form each time I tried, the macbook was turn off during the updates installation.
So that means it is obvious there is a hardware issue. I started to measure some voltages on the logic board. I saw just 2 voltages on the board:
L7030: 5.05V
L7660: 3.34V
Do you have any idea in which module area should I investigate? Any advice will help me and it will be appreciate.
Thank you in advance.
