I have a T400 (2764 CTO with a Radeon HD 3400), an Acer 23" monitor, and an Advanced Mini Dock (Part 250410U, Model 2504). I am trying to extend the display from the T400 to the Acer monitor through a VGA cable. When I plug the monitor directly into the laptop, the display extends. However, when I dock the T400 and connect the monitor to the Mini Dock, I can't get a signal to the monitor. Any thoughts? Thank you.

I played around it with it some more and I didn't have the laptop pushed far enough into the dock. It seems there are two points at which the laptop clicks while pressing it into the dock. I had already updated the BIOS and now the display extends in Intel GPU mode and with the Radeon. Thanks for your help.
