Preparation guide

  1. Inspect cable, port and power adapter for visible damage. If anything is damaged, stop using it. Try an undamaged charging-capable cable, not a data-only cable.

  2. Connect directly to the Mac and a working outlet. The original M1 Air specification lists a 30 W USB-C adapter; use a compatible recommended supply rather than assuming any USB source can charge under load.

  3. Review the battery menu and Battery settings. A high workload or an intentional battery health pause can cause Not Charging without identifying a defective battery.

  4. Save work, restart this Apple silicon Mac, and retest with lighter workload in a ventilated location. Do not perform Intel SMC key combinations on the M1.

Check the result

  • Save the observed charging behavior and workload. If it recurs, retain the comparison for Apple support.
  • Persistent unexplained charging trouble needs Apple support. Do not open the adapter or interpret this as permission to replace a battery.

Stop conditions

  • Stop using and charging a swollen or damaged battery. Do not open, compress, puncture, or attempt battery removal. Contact the manufacturer or a qualified service provider.
  • Disconnect a damaged accessory if it is safe to do so. Do not open a mains power adapter.
  • Save accessible data before restarting. Do not reset, erase, flash firmware, bypass a lock, or open the enclosure in this task.
