Initial Inspection
When dealing with Liquid Damage Repair MacBooks, the first step is a thorough cosmetic inspection of the motherboard. While there may not always be visible deformation, corrosion and residue left by liquid exposure can cause various malfunctions. In a recent repair case, we noticed clear signs of liquid damage around the non-flash chip and power supply circuits.
To begin diagnostics, we carefully installed the motherboard, connected the display assembly, and attempted to power on the device. However, the MacBook entered recovery mode immediately, indicating a deeper hardware issue. To further investigate, we connected the laptop to a Mac system and attempted a restoration. The system returned an error 14, pointing towards potential damage in the power circuits or the storage controller chip.
Diagnosing Power Supply and Circuit Damage
To get a clearer picture, we removed the motherboard for closer examination. Using a multimeter, we conducted diode mode testing across the three primary power supply rails. The readings suggested no direct short circuits, but voltage instability was present in the 1.8V power rail, where we measured an abnormal 2.6V instead of the expected 1.8V. This indicated a malfunction in the main power supply circuit.
Removing Metal Shields and Addressing Corrosion
For a more detailed inspection, we had to remove the protective metal shields covering the MacBook’s motherboard. The shields were carefully detached using a hot air gun after applying high-temperature tape to nearby connectors to prevent heat damage. Once exposed, we found extensive corrosion around various ICs and traces damaged by liquid exposure.
To fix the issue, we systematically removed the affected integrated circuits (ICs) using a hot air gun, then cleaned the bonding pads with a soldering iron and flux. After this step, we powered the motherboard again and found that the electricity leakage was still present—suggesting additional damage hidden under the remaining shields.
Final Repairs and Restoration
After removing the last metal shields, we discovered more corroded ICs. Each component was carefully desoldered, cleaned, and replaced. This time, after reconnecting the battery connector to a DC power supply, the current reading normalized, confirming that the leakage issue had been resolved.
With the power circuit stabilized, we proceeded to reassemble the MacBook. The motherboard and display assembly were reinstalled, and the battery was reconnected. Upon pressing the power button, the MacBook booted into recovery mode once again, but this time, a complete restoration through macOS successfully revived the device.
Final Testing and Customer Satisfaction
To ensure everything functioned properly, we conducted a comprehensive hardware and software test. The MacBook keyboard, trackpad, display, and power circuits all performed optimally. The laptop was successfully repaired and restored to full functionality.
