What Causes MacBook Pro Logic Board Failure?

Logic board failure can be caused by a variety of factors, including physical damage, aging, overheating, and liquid spills. If one component fails, the entire motherboard usually fails as well. Natural wear and tear can't be predicted, but it is still one of the potential causes of this type of failure. The cooling fan is essential for keeping your laptop or desktop Mac running smoothly.

If dust accumulates inside the computer, it can trap heat and make it difficult to disperse. This can lead to slower performance due to overheating. If the fan is making abnormal rattling sounds while running, it's a sign that it's failing and needs to be replaced. You can also check its status by running Apple Diagnostics.

The design of the MacBook can also contribute to logic board failure. The section of the plate with the ports and the section close to the fan slot are connected to the ground by means of the metal shield of the lower case. The screws in these areas complete the logic board's ground circuit. If a logic board is tested when it is not in the case with these screws installed, it can result in a short circuit in the logic board.

This can cause issues with the touchpad, keyboard, and other input devices. The only solution for Core Duo or Core 2 Duo logic board failure is to replace it. For Macbook Air and Macbook Pro users, an incredibly dim screen could also be an indication of a fault on the logic board. The LED screen of these laptops is controlled by the logic board, so a failure of this component could affect the brightness of the screen.
