Closing laptop lid and external display

[jhr_philips]

I'm using a laptop with an external monitor and would like to be able to shut the laptop lid and still project the image on the external monitor.

Specifically, I'd like to be able to do the following, without having to manual change the settings everytime I connect/disconnect the external monitor or open/close the laptop lid:

    When the laptop is NOT connected to the external monitor:

     * View the image on the laptop screen

    When the laptop IS connected to the external monitor:

     * View the image on the laptop screen AND external monitor, when the laptop lid is OPEN.

     * After closing the laptop lid, have the image disappear from the laptop screen, but remain on the external monitor.

     * After opening the laptop lid, have the image re-appear on the laptop screen (and remain on the external monitor).

Here are my system details:

 * Laptop: HP elitebook

 * OS: Win7

 * External Monitor: HP EliteDisplay
