MacBook Logic Board Faults We Repair for Craighall Clients
Craighall is approximately 3 km from our Hyde Park workshop — one of our regular collection areas in Johannesburg North. All MacBook models from 2015 onwards are covered — Intel and Apple Silicon. Every fault is assessed at component level with a written quote before any repair proceeds.
No Power
MacBook shows no signs of life. We trace the power rail from the charging port through to the SoC power domain. The most common cause we see from Craighall clients is USB-C controller or power management IC damage from load shedding surges — South Africa's grid instability accounts for roughly 35% of the no-power boards that arrive at our Hyde Park workshop.
No Display / Black Screen
The machine boots — you can hear the startup chime or feel the trackpad click — but the screen stays black. In our experience this is usually a backlight fuse, display driver IC, or on older Intel models a GPU fault. We diagnose the exact failed component before quoting.
Liquid Damage
Coffee, water, or condensation causes progressive corrosion on the logic board. We have seen boards from Craighall where a small spill two weeks earlier quietly corroded a power rail. Ultrasonic cleaning followed by targeted component replacement at board level. Time-critical — the sooner the board reaches us, the better the outcome.
USB-C / Thunderbolt Failure
No charging, no data transfer, or no external display output on one or both USB-C ports. The CD3217 or similar controller IC is a discrete, replaceable component. We see this fault frequently after third-party charger use or load shedding events.
Overheating / Shutdown
Unexpected shutdowns under load traced to failed voltage regulators, shorted capacitors, or thermal sensor faults on the logic board. Not a fan or thermal paste issue — a board-level electrical fault that requires component-level diagnosis.
Fan Running at Full Speed
Continuous full-speed fan operation even at idle. This is an SMC or thermal sensor fault on the logic board — not dust buildup. The specific failed sensor or SMC component is identified and replaced. We repair this at component level rather than replacing the entire board.
