My macbook pro will not sleep with a VGA monitor connected, via a MiniDisplayport to VGA adapter. When I close the lid, all of the windows shift over to the second screen, and the light on the macbook continues to stay solid (rather than pulsing like it usually does when the monitor is not plugged in).

I can unplug it, but it is a nuisance and I'm wondering if there's a way to fix it.

I'm afraid that's the appropriate behaviour, and it's called Closed Clamshell or Closed Display mode.

Using the Option+Command+Eject shortcut will put the computer to sleep.

On the other hand, unplugging the Power Adapter from the MacBook and then closing the lid, will do the trick, too.

  • That's too bad. I've found a command online to disable this, now that I know the name, trying to do it now: sudo nvram boot-args="iog0x0" – Blue_Dragon360 Dec 29 '14 at 22:00

    Didn't work :/ Thanks for the info though! It seems silly that you can't disable it. – Blue_Dragon360 Dec 29 '14 at 22:09

The macbook will not go to sleep if an external monitor is connected. What you can do is put your mac in sleep with the following combination:

Cmd - option/alt - eject (on newer macs) Cmd - option/alt - power button (on older macs)
