Known Failure Points

The most common failure types, sorted by when they typically appear.

Keyboard Key Failure

The MacBook Pro 14" M3 uses the Magic Keyboard with scissor-switch mechanism. The keyboard is integrated into the top case assembly — a single failed key triggers a top case replacement costing $400+ from Apple service. Debris ingress and liquid spills are the most common causes.

Debris visible under keycap
Backlight LED failed for a specific key

Fan Bearing Wear and Dust Accumulation

The MacBook Pro 14" M3 has two small dual-shaft fans for active cooling. Fan bearings wear over years of use, causing louder operation at moderate speeds — a normal bearing wears quietly even at high RPM, while a worn bearing is audible at medium RPM. Simultaneously, dust accumulates in intake vents along the bottom and through the hinge. Professional workloads accelerate both issues. Performance can drop 15-25% when fans can't maintain target CPU temperatures.

Warning signs:

Unusual grinding or clicking from fan area
CPU performance benchmarks lower than when new
Keyboard deck noticeably hotter during compilation or export

Battery Degradation

The MacBook Pro 14" M3 uses a 72.4 Wh battery rated for 1000 charge cycles to 80% capacity. Professional workloads — code compilation, video rendering, ML training — draw 30-40W sustained, generating heat that accelerates battery chemical aging. The M3 is more efficient than Intel predecessors but still more demanding than the fanless M3 Air. Apple replaces the battery using pull-tab adhesive, but in many service scenarios the entire top case is replaced.
