Today we will share a case about repairing a MacBook Pro 13" 2018 (A1989) that won't turn on. In the first place, we used MacBook (BY-3200) Power Cable to observe the change of boot voltage and current. The voltage values related to the boot circuit on the motherboard were found to be normal after measuring. To determine whether the fault was caused by data problems, BY-T200 Data Assistant was used to read and write the data of T2 chip ROM. After rewriting the ROM data of T2 chip, the MacBook could turn on and enter the system. The not turning on fault has been cleared.
