If your MacBook Pro (15-inch, Late 2016), MacBook Pro (13-inch, Late 2016, Four Thunderbolt 3 Ports), or MacBook Pro (13-inch, Late 2016, Two Thunderbolt 3 Ports) is powered off, it turns on when you do these things:
- Open the lid of your Mac, even if it's not connected to power.
- Connect it to a power adapter while its lid is open.
- Connect it to a power adapter while its lid is closed and it's connected to an external display.
