What is board level computer repair?
The logic board of any computer is the circuit board, which handles interactions between different components, including graphics cards, CPU, cooling fans, storage drives, RAM, etc. On a Mac, it is called the logic board, and it ensures that all functions are working optimally.
Given the important role of the logic board, it is understood that your Mac will not work if anything happens to the board. That is when you will need professional board level repairs from a seasoned technician.
Signs you need board level computer repairs for your Mac
Like any other Mac component, the logic board is also prone to wear and tear after prolonged use. However, dust and dirt, liquid damage, overheating, and electrical surges can affect the circuit board. Regardless of the cause, the issue needs instant attention to keep it from escalating.
The following are the common signs of a faulty or damaged logic board:
- System crashes
A MacBook with a faulty logic board will fail or crash. The device may boot but will unexpectedly crash or freeze frequently without warning. The device may crash on login, after waking from sleep, in Safe Mode, or when unplugged. The system may also keep shutting down or restarting abruptly.
- Battery not charging
A damaged logic board affects the charging ports. So, your laptop’s battery will not charge even if it is connected to an electric outlet.
- USB ports not working
All USB ports on your Mac are connected to the logic board. So, any issue with your logic board may be evident through problematic USB ports. As a result, your Mac will not recognise any device plugged into the ports.
- Mac will not turn on
If your Mac does not turn on after pressing the power button or Touch ID button, and you do not hear the startup chime or a spinning fan, and you see no visuals on the monitor, these are the signs of a defective logic board.
- Graphics and display problems
Distorted graphics, grey scales, or coloured lines are common signs of graphics and display problems. The logic board is most likely to be the culprit because the screen and graphics are directly attached to the logic board in MacBooks.
- System diagnostics test failure
To perform hardware diagnostics tests to identify problems with your logic board, you need to perform tests on different parts, like RAM, GPU, and CPU. You can do this by using the built-in Apple Diagnostics in macOS using these steps:
- Shut down your Mac.
- Long press the power button.
- Release the power button when you see the Options screen.
Press Cmd + D.
- Audio not working
Audio devices are also soldered with the logic board that enables songs on your Mac. If the audio drive stops producing sound, it can be due to a faulty logic board.
Besides those mentioned above, there could be other signs indicating a problem with your logic board. These may include the battery draining too fast, an overheating device, and many more.
MacBook computer repair for logic board
As we mentioned above, the logic board is the most critical component in any Mac. So, you should be extremely careful when handing over your device for board level repairs.
However, there are some situations where board level repair might not be a great idea. These situations typically include:
- Irreparable damage
- Outdated hardware
- Extremely high costs for board level repairs
If you are clueless, you can reach out to expert Mac technicians who are reputable and experienced in working with logic boards. At 73inc, we have repaired many logic boards at highly competitive costs. We will diagnose your MacBook for the underlying cause of the problem and suggest whether it is within or out of the scope of the repair.
There are some board level problems that cannot be resolved, and for such issues, we suggest a replacement. For example, in case of CPU failure, we suggest replacing the logic board. This is because it is very challenging to replace a CPU chip. On top of that, it is expensive, and the success rate is also quite low. At 73inc, we quote customers for both options, including repair as well as replacement.
