MacBook Pro won't sleep with external monitor
Hello,
have a problem. I'm using external monitor with my MacBook Pro. If I close the lid, I see all windows on external monitor and Yosemite won't sleep. Can you help me please? My external monitor is Samsung 21.5" and I'm connecting it to MacBook Pro via DVI.
Thank you
MacBook Pro (13-inch Early 2011), OS X Yosemite (10.10.2), null
