MacBook Air A1466 startet nicht wegen winziger Korrosion

Today we have a 13-inch MacBook Air (model number A1466) in the workshop. According to the customer, the device won't turn on. Only about 0.046 A is flowing through the connected charging cable, which is clearly insufficient for a functioning MacBook Air. We investigated the cause and found a fluctuating voltage between 0.1 and 0.4 V on the 5V line. On the back of the logic board, we finally located the source of the problem at the chip that generates this voltage.
