I'm not sure if this is the right area for this, but I'll take a shot at it.
I have an Acer Extensa 4620z laptop that I'm using as my replacement workstation. I figure it made mroe sense to have a lightweight laptop I just "dock" versus having two systems.
Everything works ok except the monitor output. When I hook up an external monitor, I get a picture just fine but I can't blank the laptop screen. If I close the laptop lid, the system will work ok but after a little while the screen will start to "blink". Almost like its trying to put itself to sleep or something.
