Hello Wallclock,

The article linked below details how to go about using your MacBook Pro in closed-clamshell mode (i.e. only utilizing your external display).

I think Wallclock means how to use solely the external monitor with the display on macbook turned off, while which the keyboard and trackpad are still active. Because I have the same question. It would be nice to save energy while using external monitor and to save money for external keyboard and mouse. thanks.
