| MacBook Pro 16" 2021 Logic Board Replacement |
|
|
Introduction |
| Use this guide to replace the logic board in your MacBook Pro 16" 2021. | | | ***Note that Touch ID will not function after replacing the logic board.*** The MacBook Pro’s original Touch ID sensor is uniquely paired to the logic board at the factory—and without Apple’s proprietary calibration process, even a genuine replacement Touch ID sensor from another MacBook Pro won’t work. | | | ***For your safety, discharge the battery below 25% before disassembling your MacBook.*** This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, [[What to do with a swollen battery|take appropriate precautions|new_window=true]]. |

Conclusion |
| ***To reassemble your device, follow these instructions in reverse order.*** | | | Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it. | | | Repair didn’t go as planned?
