MacBook Air 2018 Won't Charge - USB-C Port Repair Saved RM 2,100
Logic board level USB-C charging port replacement
The customer’s MacBook Air completely stopped charging after a charging cable incident. We performed precision micro-soldering to replace the damaged USB-C port on the logic board, restoring full charging capability for RM 680 - vs RM 2,780 for a new logic board.

The Transformation
Before & After Results
The customer, an MBA student in Kuala Lumpur, yanked his charging cable while rushing to class, damaging the USB-C charging port on his MacBook Air 2018. The laptop stopped charging completely - the battery was at 15% and dropping. He tried different cables and chargers but nothing worked. The port looked physically damaged with bent pins. Apple's diagnosis: logic board replacement required at RM 2,780 because the USB-C ports are soldered directly to the logic board. With exams coming up and his thesis on the laptop, the customer needed an urgent, affordable solution.
MacBook won't charge at all (stuck at 15% battery)
Physically damaged USB-C port with bent pins
Tried multiple cables and chargers - none work
Port loose and wobbly
Apple diagnosis: Logic board replacement RM 2,780
Exam deadline pressure with thesis on laptop
Our micro-soldering specialist performed a component-level repair. Under microscope inspection, we confirmed the USB-C charging port controller IC was damaged along with the physical port. Using a hot air rework station and precision soldering equipment, we carefully removed the damaged USB-C port from the logic board without affecting surrounding components. We then installed a new original USB-C port assembly and verified all data pins and power delivery connections. After testing charging at various wattages (30W, 45W, 61W), we confirmed full functionality and proper power negotiation.

Proper USB Power Delivery negotiation
Firm, secure port connection
All USB-C functions working (charging, data, video)
0-100% battery in 2 hours (normal)
Saved RM 2,100 vs logic board replacement
