What Is a Logic Board?
Modern computers rely on a sophisticated series of connections and processes to achieve the outstanding degree of functionality that is considered the industry standard. Typically, consumers divide desktop and laptop computers into two distinct species – Apple and PC machines.
What are the symptoms of a bad motherboard/logic board on a MacBook Pro laptop or iMac?
- The lights in the front turn on, but the computer does not boot or nothing appears on the screen.
- System beeps and does not boot to OS.
- The screen shows gibberish or distorted video images.
- Your MacBook laptop freezes intermittently and you have to turn the system on & off to bring it back on.
- Mac system shows the black screen of death (kernel panic), and you can’t go any further.
- Power issues such as:
- System does not turn on at all.
- Battery does not charge even after you changed the charger/AC adapter.
- Your MacBook sporadically turns off or shuts down by itself.
- Non-functioning ports or components on the motherboard such as bad USB, audio, video, DC power jack, wireless, etc
What are the causes of such problems?
- The built-in GeForce or Radeon video card on the motherboard is going bad or it’s already defective.
- Due to too much heat created inside the MacBook, some chips on the motherboard have been damaged. This can happen due to a bad fan or too much dust inside the fan is not letting it spin at optimal speed. This can cause overheating on the logic board and internal components.
- Any type of water or liquid spill on the unit or even a damp environment.
- General wear and tear after years of use and abuse!
- Bad power DC jack port. The MagSafe AC adapter port has gone bad or has broken pins.
