MacBook Pro M1 won’t power on

Possible causes

These are the areas that should be investigated in this case:

The cause is confirmed by measurement and actual behaviour, not by similarity with another Mac.

How diagnosis is carried out in the workshop

Charger negotiation and initial current draw are measured. Then the voltage sequence is checked and whether another Mac detects the device in DFU mode. A reactivation preserves data; a restore can erase it.

We also check for secondary damage. A faulty input can affect the charging circuit; liquid can reach multiple connectors; and a power drop can leave file-system damage.

Data depends on the original logic board

On Apple Silicon, storage is integrated and encrypted. Replacing the logic board does not automatically transfer documents, photos or projects. When no backup exists, the strategy must prioritise the original board and avoid actions that erase content.

Before restoring firmware, reinstalling or accepting a replacement, consult the Mac data recovery.
