When you see a light grey screen or the Apple logo splash screen, you’ll know the computer passed POST. The POST looks at things such as memory, CPU, and network interfaces. For starters, see if your computer passes POST (power-on self-test) when you start it up.

The first thing you need to do before repairing a Mac logic board is to do as much testing as possible to diagnose the issue. This is why it is so important to test your system and confirm logic board faults so that you know what to do next or if you’re worried contact a logic board repair specialist. But even if your logic board comes back to life after showing signs of problems, the bad news is that it is likely to crash again. Unfortunately, it isn’t always obvious when your logic board is faulty. Or even worse your machine may show no signs of life at all which could easily be a logic board failure too. When the logic board has problems, so will your screen backlight. This is because the logic board controls the LED screen of specific Mac computers.

If the screen is becoming so dim that you can’t read anything on it, it could be that your logic board is going bad. This is because USB ports are connected to the logic board on most models, so a problem with the logic board can automatically cause a problem with the USB ports.Īnother way to tell if your logic board is faulty is to look at your computer screen. If you find that the problem is with the system management controller, you may have an issue with your logic board.Īnother issue that suggests that you have a problem with your logic board is if your USB ports aren’t working correctly.

This is because there are complex and delicate parts in your computer that you’ll have to navigate around in order to fix it (hundreds of them!), keep in mind that the logic board is the main circuit centre of your computer. This means that if the logic board fails for some reason, the different parts of the computer won’t be able to communicate with one another, and in practical terms, this usually means some sort of hardware issue is on the way.Īnother difficulty you may encounter when you suspect that there’s a failure with the logic board is that this type of problem is usually difficult to diagnose and even more challenging to repair. The logic board maintains the normal function and is the main circuit board that allows components to interact with one another. For reasons unknown to most of us, Apple decided to call their motherboards “logic boards,” but the two are essentially the very same thing.
