How To Turn On Macbook Pro With External Keyboard Backlight
Many people are using the closed-clamshell or closed-display mode to take advantage of the bigger screens at home. However, it’s a little inconvenient if you connect to external monitors most of the time because you have no way to turn on the MacBook when the lid is closed.
When I used my MacBook Pro with a Dell monitor, I often have to open the lid, press the Power key, close the lid and then put the MacBook to the Twelve South BookArc mod stand again.
In case you are using the same setup, probably you have to do the tedious process every day as well. I tried to find a solution but it seems like powering on a MacBook without opening the lid is impossible. When you shut down the Mac, all connections are terminated, so there is no way to use an external device to start up the MacBook.
Update: The MacBook now turns on automatically once it is plugged in, so it makes things much easier. I connect my MacBook Pro to my BenQ monitor via the USB-C port with power delivery, the MacBook will power on when I turn on the monitor.
