      Summary: Find useful information related to a dead or unbootable MacBook due to a logic board failure. If this error has made your Mac unbootable, try professional Mac data recovery software to safely access & retrieve your files.

      Mac systems are quite reliable. Unlike their contemporaries, Macs offer stability and reliability in terms of both hardware and software. But even with a sophisticated platform, Macs are prone to failure – at times, severely – resulting in errors like a dead Macbook or lost data.

      The most common issue behind a dead MacBook is the logic board failure. Logic board is the other name for a Mac’s motherboard. A failing logic board could result from malfunctioning USB port, problematic internal components, etc.

      As the logic board is a critical component, any issue with it could hamper the usability of the device or, worse, result in a dead MacBook.

      Reasons Behind Logic Board Failure

      A logic board inside a Mac is an electronic component susceptible to various issues, including rendering a MacBook unbootable or dead. Some of the reasons behind logic board failure are –

      • Physical damages
      • Liquid spill
      • Electric surge
      • Overheating
      • Malfunctioning components
      • Electrical surges

      Various Signs of Logic Board Failure in a MacBook

      As the logic board and various other components like memory, storage, etc., are now soldered onto the board, repairing a faulty MacBook logic board has become nearly impossible for an average user.

      Therefore, you should always look out for signs of imminent logic board failure on your MacBook, like:

      Sign 1: Unexpected System Crashes

      The logic board is the brain of your MacBook that controls various functions and components. Malfunctioning parts or circuitry could result in unexpected system crashes, unsuccessful POST, a MacBook stuck on the Apple logo screen, a frozen Mac, etc. These are some issues you could face due to a failing MacBook logic board. Prolonged usage could also lead to a dead MacBook.

      Sign 2: Battery Draining Fast or Not Charging

      Significantly decreased power holding capacity or heightened power usage could also indicate a possible logic board failure. Sometimes, no matter how long you charge your MacBook, the battery gets used up pretty fast, resulting in abrupt shutdowns. In this case, you should reduce the number of tasks running on your Mac and check the battery health from the System Settings.

      Similarly, there might be an issue with either USB-C ports (soldered to the logic board) required for charging your MacBook. Any issue with the logic board or ICs near the charging port could also lead to MacBook charging issues.

      Sign 3: Negligible Audio Output

      If you cannot hear sound on your MacBook even after playing at full volume, it is a clear case of audio component failure on the logic board. This issue can also lead to the failure of the 3.5mm audio jack or a bluetooth driver.

      Sign 4: Graphics and Display Problems

      Many MacBooks launched before the M1 Macs could show fans spinning upon boot with nothing displayed on the screen or a very dim light on the screen. This could be due to a possible display failure or an issue with the port connecting the display to the logic board.

      Again, this problem could cause your MacBook to not recognize or connect with external displays connected via Thunderbolt ports.

      How to Recover Files from a Dead MacBook?

      If case you have a MacBook that won’t turn ON, you can use Stellar Data Recovery Professional for Mac to safely recover your files.

      This advanced tool easily finds recoverable data and recovers it in a few clicks. If your MacBook turns on but doesn’t go past the apple logo, use the software to recover data without even creating a recovery media. You only need an active internet connection to use this software.

      You can follow this guide to recover data from an unbootable MacBook/iMac/Mac mini.

      Notes –          

      • However, in case of severe logic board damage, you should take your MacBook to an authorized Apple store for diagnosis. They will help you recover your data in no time.
      • If you have an unbootable or dead MacBook that predates the M1 silicon MacBook era, the storage drive inside (SSD/HDD) is likely removable. Unplug it and plug it into a working Mac to recover data.

      Tips to Maintain a Data Backup

      While file recovery is an absolute solution in many data loss scenarios, maintaining regular data backups can help you prevent unexpected data loss. Below are a few ways you can use to maintain regular data backups –

      • Use iCloud to take off-site file backups
      • Use Time Machine Backup drive to save file snapshots/timestamps
      • Use an external drive to maintain a regular backup of your data and files
      • Maintain backups at multiple locations/devices

      Wrapping It Up

      A MacBook with a failing logic board indicates imminent failure and subsequent data loss. In this guide, we looked at various signs that can help you figure out a malfunction with the logic board. If you see any signs indicating a failing logic board, use a professional Mac Data recovery software to safely recover your files.
