Fault Finding on Macbook Pro Not Turning On Repair
13″ Macbook Pro came to our Macbook Repair workshop in Adelaide. When connected to the bench power supply, it would not draw any current. Its original adapter will show an orange light but not engage to power on.
With a pressed power button, Macbook stays with a black screen, and no indication of life is present.
Macbook Pro Not Turning On Repair Process
The first step is to take apart and inspect for visible damage. As soon as we lifted the logic board from the case, we noticed the burn mark on the logic board. Additionally, the melted keyboard and backlight sheet also was unquestionable indicators of the high heat point.
There is one solution for such failure, and it is a Macbook Not Turning On Repair in Adelaide.
We went ahead and strip down the board, positioned it on our Repair Bench here at @ITSolve.Repairs and started checking for potential short circuits and damage in the burned area of the logic board.
We have identified the blown component as a capacitor. They are designed to filter the ripples in the voltage lines. We can guess the fault occurred either by a worn-out capacitor, which just needed a small pulse to knock it off. Or there was a power surge in the household which may send a more significant ripple than the worn-out cap could handle.
