At the office i have a Dell latitude D600 laptop, and when i connect the laptop onto the docking station and then try to power the system on, all the lights on the laptop light up and then turn off within seconds. What i'm asking is, is this normal? Because it seems the only way to use the system with the dock station is to turn the system on before docking it. Any advice on this? I've also tried a different dock station, but it does the same thing.
