What's going on
A completely drained battery may need several minutes of charging before the Mac shows any sign of life. Apple silicon Macs have no SMC to reset; holding the power button for 10 seconds does an equivalent restart.
If the Mac starts but the screen is black, try increasing brightness, connecting an external display, or restarting into macOS Recovery.
Signs of the problem
- No response to the power button.
- Black screen but fans or keyboard lights are on.
- Charger light doesn't come on.
Common causes
- Drained battery or faulty charger/cable.
- Mac is on but display is off/dim.
- Firmware or SMC state (Intel).
- Liquid or hardware damage.
Fixes to try, in order

- Reset SMC (Intel Macs)With T2 chip: hold Control + Option (left) + Shift (right) for 7 seconds, then add Power for 7 more, release, wait, power on. Older models differ. See Apple's guide for yours.
