Can you explain how you are trying to do that. The screen switch mostly depend on the video driver. If that is not proper then it will not work. If you are using Windows 7, then just right click on Desktop and click on Screen Resolution. See whether the secondary monitor you had attached is detected or not. If not then try to run a fresh video driver update. This will resolve the problem. The laptop has NVIDIAGeForce 9300M GS graphic card. Try to check the settings through Nvidia Control Panel also. It lies in the system tray.
