Pattern to record: Power is present but the Mac remains black or repeatedly enters recovery behaviour.

Use the correct Mac power design

Use the exact Apple-silicon MacBook Air model to identify its charging ports and supported adapter. A black display alone does not prove the Mac is unpowered; check for other startup signs before pursuing the input circuit. Startup firmware is incomplete or corrupted and normal boot cannot begin.

Power and data precautions

Mac batteries and logic boards must be isolated with model-appropriate procedures. A restore can erase data, so the selected recovery action must be understood first.

Model-specific checks

1. Verify the correct charger, inspect all ports and separate display absence from true no-power behaviour.
2. Identify the Mac generation and follow its documented recovery procedure after confirming stable power; revive/restore procedures apply only to supported Apple-silicon or T2 models.

Repair and startup verification

If the checks support this cause, use the supported recovery action for that model, distinguishing a data-preserving revive from an erasing restore where those options exist. Verification should cover cold start, charging on each supported port, battery operation, sleep, wake and restart.
