2019 16-inch MacBook Pro no power case study explains how data was recovered from an unresponsive MacBook Pro after a logic board power fault. The laptop would not turn on or respond to charging, and the issue was traced to a short circuit affecting the NAND power line.

Case Study Summary

  • Device: 2019 16-inch MacBook Pro (A2141)
  • Problem: No power and no response
  • Fault found: Short circuit on the NAND power line, with corrosion under a component
  • Recovery result: Over 800,000 files recovered, including 50,000 photos and videos and 25,000 documents

2019 16-inch MacBook Pro no power case study technical overview

This MacBook Pro arrived completely unresponsive. In the video, the engineer used a multimeter to confirm abnormal readings and then narrowed the fault to a short circuit on the NAND power line. Because the NAND chips store the data, a power supply failure at this point can stop the entire system.

Corrosion was found under an original component on the logic board. The recovery required component-level work to restore stable power to the NAND area so the data could be accessed safely.

Logic board repair steps used to access the data

Based on the video, the engineer completed the following repair work as part of the recovery process:

  • Identified the short circuit on the NAND power line using a multimeter
  • Found corrosion under an affected component
  • Replaced the NAND power IC
  • Removed a damaged capacitor
  • Reballed the power chip to rebuild the connections

Data recovery results

After the repair work restored stable power conditions, the data was recovered successfully. The video states that over 800,000 files were saved, including:

  • 50,000 photos and videos
  • 25,000 documents
  • Applications and other user data stored on the onboard SSD

Imagine this. You could be working on your laptop. Then suddenly it turns off dead. Will not turn on even after trying to charge it and it’s suddenly unresponsive. Hi, it’s Mike here at Payam Data Recovery and I just watched one of their data recovery engineers figure out what went wrong with this unresponsive 2019 16in MacBook Pro. This MacBook came in with absolutely no power and I watched as the technician made his diagnosis with a multimeter. After some thorough detective work using specialized tools, he pinpointed the problem. A short circuit on the NAND power line. The NAND chips are where all the data is stored. So when their power supply fails, the entire system unfortunately goes down. He found corrosion under the original component. This meant that he had to not only replace the NAND power IC, but also remove a damaged capacitor and completely reball the power chip, essentially rebuilding hundreds of microscopic connections. If this MacBook went to another repairer or data recovery company, it would have been deemed impossible to recover and the owner would have been told all their data has been lost forever. Instead, at Payam Data Recovery, over 800,000 files were saved, including 50,000 photos and videos, 25,000 documents, and all the applications and every other file that was ever saved to the onboard SSD. This case study shows that if you have a damaged MacBook and you have been told that the data is gone and you need the logic board replaced, reach out to a company like Payam Data Recovery and there is always hope that your files can be saved.
