Hey Kappy,


I have a bluetooth keyboard, mouse, and external monitor. When I am in clamshell mode and the AC charger is plugged into my laptop it works, but when the AC charger gets unplugged clamshell mode ends. Is this an energy saving setting? How can I use clamshell mode without the charger.


thanks,

Hi,


You need to have the laptop "plugged in." Per Apple (Use your Mac notebook computer in closed-display mode with an external display - Apple Support):


Requirements for closed-display mode

To use closed-display mode with your Mac notebook, you need:

  • An AC power adapter
  • An external keyboard and mouse or trackpad, either USB or wireless
  • A USB-C to USB adapter if you're using a USB mouse or keyboard with MacBook (2015 and later) or MacBook Pro (2016 and later)
  • An external display or projector
