I have a Dell Latitude E6510 laptop and a docking station. Without the Docking station everything works fine but if i connect an external monitor and close the laptop, Fedora will not shutdown probably. Instead of powering off the computer it just loggs off the current user, stays on the logon screen and switches to hibernate-mode. If i try to logon again, the network-connection is unavailable and i can't restart it. After i reboot the system (with laptop open) everything works fine again. Also i need to open the laptop to see the logon screen but this is not important because i just have one user on this machine.
