Check the result
- Save the reference code in your own private service notes. This website records only that a result was available.
- If diagnostics cannot run, or a code reports an issue, contact Apple with your observed result; do not guess the failed part.
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.
