Product: HP Powerbook 4440s
Operating System: Microsoft Windows 7 (32-bit)

 My HP Powerbook 4440s goes black when I plug into a projector.  The projector says no signal.  I tried a differnet computer and it connected right away to the projector.  I have uninstalled and reinstalled (from intel website) the graphics card driver and rebooted and it was still going black.  I have set the settings in the control panel and used windows + p to select duplicate.  Everytime I plug the VGA in the screen goes black and when I unplug it my control panel and windows +p settings are back to computer only.
