My Dell e6400 no longer can extend desktop. The external monitor detected and I can changed the resolution in display properties. But the external monitor reported on a power save mode. To confirm this, I unplugged the cable and the external monitor shown 'no signal detected' message.
Tried with many cables and monitors/projectors.
EDIT: Yes, i did enabled second display. I did this using Windows Mobility Center.

Did you enable extending desktop to the second display? – billc.cn – 2012-05-07T11:21:55.907
