MacBook Pro 13” Unibody A1278 820-2879 Not Booting No Boot Chime Repair


MacBook Pro A1278 Not Booting 

MacBook Pro A1278, turns on but does not boot as well as the fan is running too fast. After checking the logic board in the microscope, we found out that one capacitor was knocked off from the board. We then replaced the capacitor with another one. The job was then done.
