Repair Process
Step-by-Step Timeline
Emergency Diagnosis
Customer brought iPad at 3% battery. Immediately connected to power bank via test cable to keep device alive during diagnosis. Inspected port under microscope - found heavy corrosion on pins 4-7.
Device Disassembly
iPad Air 4 uses adhesive-only construction with no screws. Applied heat to soften adhesive and carefully lifted display using suction cups and guitar picks. Protected Touch ID cable during opening.
Battery Disconnection
Located and disconnected battery connector to ensure safety during logic board work. This prevents shorts when handling charging port flex cable near power circuitry.
Logic Board Removal
Removed motherboard screws and carefully lifted logic board. Disconnected all flex cables including display, cameras, and antenna. Placed board in anti-static mat for port replacement work.
Charging Port Flex Cable Replacement
Removed 4 tri-point screws securing old Lightning connector assembly. Cleaned corrosion from logic board contact points using isopropyl alcohol and soft brush. Installed new original connector flex cable.
Reassembly & First Power Test
Reconnected battery and logic board. Before sealing display, tested charging with multiple cables - 5V, 12V, and 20V USB-C PD all working. Confirmed 30W fast charge negotiation successful.
Display Resealing
Applied new pre-cut adhesive strips around iPad perimeter. Aligned display carefully to ensure proper fit and uniform gaps. Used clamps to press assembly together for strong bond.
Final Testing & Battery Charge
Left iPad charging from 3% to 80% while testing all functions. Verified charging speed (0-50% in 45 minutes = proper 30W). Checked data integrity - all student notes intact.

"My iPad Air is my whole university life - notes, textbooks, everything. When it wouldn't charge and hit 3%, I panicked. Apple said they'd replace the whole unit for RM 1,699 and I'd lose my data. Siti fixed just the port for RM 299 in 90 minutes and kept all my files. Absolute lifesaver!"
