Usualy after not using the computer for some time, I want to turn it off. But than a (ACPI/driver?) bug shows up:

On the Dell E6500 (Vista 64 SP1) with Dockingstation E-Port Plus I can not turn of the computer using the power button of the docking station if the screen blanker  (black screen only) has turned off the monitor.  I need to waken up the monitor again everytime I want to switch off (suspend to ram) the computer.
