If your MacBook will not turn on, shuts down randomly or shows a black screen, the fault may be on the logic board. Many logic-board faults can be repaired at component level, but viability depends on the fault, model, board condition, extent of damage and available repair pathway.
From our repair lab in Grey Lynn, Auckland, 73inc uses board-level diagnosis and microsoldering where appropriate to identify and repair failed components. Initial logic-board diagnosis is normally completed the same day or next working day, and repair options are confirmed after assessment.
If your MacBook will not turn on, shuts down randomly or has a black screen, the fault may be on the logic board. Many logic-board faults can be repaired at component level, but whether repair is viable depends on the fault, exact model, board condition, extent of damage and available repair pathway. Our Grey Lynn repair lab uses board-level diagnosis and microsoldering where appropriate to identify and repair failed components.
We assess and diagnose the MacBook first, explain the findings and available repair options, then confirm the quote before approved repair work goes ahead. An assessment fee applies. If the approved quoted repair is completed successfully, the assessment fee is deducted from the repair total. If an approved repair is attempted but cannot be completed successfully, no additional repair charge applies beyond the assessment fee.
Turnaround: Initial logic-board diagnosis is normally completed the same day or next working day. Once a repair is approved, general logic-board repairs are normally completed within 1–2 working days. Complex logic-board or liquid-damage repairs may take 2–5 working days depending on the fault, complexity and parts. These are normal operating timeframes, not guarantees. Repairs include a 90-day return-to-base warranty on applicable parts and labour. Standard warranty terms apply.
Device: MacBook Air M1 (2020).
Customer symptoms: The MacBook arrived with no power and no charging.
Diagnosis: Board-level testing identified a faulty USB-C controller preventing successful USB-C Power Delivery negotiation. In this test, the input remained at approximately 5V.
Repair process: Replacing the first faulty controller restored negotiation to 20V, but charging still did not work and current draw remained at approximately 0.03A. Further troubleshooting identified a fault in the second USB-C controller. That controller was also replaced.
Verified outcome: With both faulty controllers replaced, normal Power Delivery negotiation, charging and power functionality were restored. The post-repair worksheet records passing checks for the logic board, keyboard, battery, trackpad, camera, Wi-Fi and Bluetooth, sound, ports and screen.
This repair illustrates why restoring the expected charging voltage does not, by itself, establish that the entire charging system is working. The voltage and current readings describe this individual test, not universal requirements for every MacBook. The repair outcome is specific to this device and does not guarantee the same result for another fault.
If you are weighing up whether it is worth fixing an older MacBook versus buying new or refurbished, read our full breakdown: Logic Board Repair vs Buying a New Mac in NZ. The right pathway depends on the exact MacBook model and configuration, its age and overall condition, the fault and board condition, repair viability, the repair quote, current device value, data importance, expected remaining useful life and how you use the MacBook. After diagnosis, the appropriate outcome may be component-level repair, a replacement board or another replacement pathway, separate data recovery, replacing the device, or deciding that no repair is economical.
If replacement makes more sense, explore our refurbished MacBook range. Explore related services on the Apple Repairs hub.
The logic board is Apple's term for the motherboard - the central component connecting the CPU, memory, storage and every other part of the machine. On Apple Silicon MacBooks, the CPU, GPU, RAM and storage controller are combined into a single chip.
Initial logic-board diagnosis is normally completed the same day or next working day. Once a repair is approved, general logic-board repairs are normally completed within 1–2 working days. Complex logic-board or liquid-damage repairs may take 2–5 working days depending on the fault, complexity and parts. These are normal operating timeframes, not guarantees.
Logic-board repair at component level can cost a fraction of replacing the complete logic board. The exact repair cost depends on the fault, model, board condition and work required, and we confirm the repair options and quote after diagnosis.
Many liquid-related logic-board faults can be repaired at component level, but viability depends on the affected components, corrosion, board condition, extent of damage and available repair pathway.
Common causes include liquid spills, power surges, physical damage, faulty charging accessories and general wear over time.
Repair pathways vary depending on the MacBook model, fault, coverage and provider. Depending on the circumstances, options may include an Apple-authorised repair pathway or independent component-level repair where that approach is viable. We explain the available options after diagnosis so you can decide which pathway is appropriate for the device.
We assess Intel and Apple silicon MacBook Air and MacBook Pro models. The repair pathway available depends on the exact model and architecture, the fault, board condition, parts and the work required.
Device repair and data recovery are separate outcomes. If preserving the data is the priority, or the board cannot be economically repaired, we can discuss whether a separate data-recovery pathway is appropriate. Recovery depends on the fault, storage architecture and device condition and cannot be guaranteed.
