Sunninghill sits between Sandton and Fourways — both areas we collect from daily. All MacBook models from 2015 onwards are covered — Intel and Apple Silicon. Faults assessed at component level. Written quote before any repair proceeds.
No Power
MacBook shows no signs of life. Power rail diagnosis and component-level repair. Most common cause: USB-C controller or power management IC damaged by load shedding surge.
No Display / Black Screen
Machine boots but screen stays black or shows artefacts. Backlight fuse, display driver IC, or GPU fault identified and repaired.
Liquid Damage
Coffee, water, or condensation causes corrosion. Ultrasonic cleaning followed by targeted component replacement at board level.
USB-C / Thunderbolt Failure
No charging, no data, or no external display on USB-C ports. Controller IC or port board replaced at component level.
Overheating / Shutdown
Unexpected shutdowns traced to failed voltage regulators, thermal sensor faults, or blocked power rails on the logic board.
Fan Running at Full Speed
SMC fault or failed thermal sensor causes fans to run continuously. Board-level diagnosis and SMC component repair.
