Preventing Laptop Screen to Shutdown?

[Dom]

Im currently using my Laptop + External Monitor configuration, with Hackintosh when i closed the lid, everything was normal, screen powered off, but the Screen setup remained the same, but in XP/7, when i close the Lid, it removes the Laptop LCD from the configuration, leaving only my External monitor and upon opening, everything moves back to the Laptop, cloning my Laptop with my External display.

So if i close my Laptop, the Screen Config gets messed up..., anyone knows of any solution to this? tried looking around, failed.

Any help is greatly appreciated!
