The MacBook Air 13" Early 2015 (A1466) logic board contains key power-related chips such as the U7100 charging IC, ISL6259, U2890, U1900 PMIC, and several MOSFETs.
Common symptoms include the device not charging, no power, charger light not responding, or abnormal heat near the charging port or logic board.
Technicians diagnose faults using current meters and schematic analysis, then carefully desolder and replace faulty ICs with compatible OEM-grade components.
Repairs are performed on anti-static workbenches using hot air rework stations, followed by comprehensive testing of voltage rails, thermal behavior, and charging stability.
Repair typically takes 1–2 business days and includes a 1–3 month technical warranty limited to the repaired issue (not covering unrelated future board failures).
