Dell E6510, i7, windows 7 32bit: fresh install, previously running XP sp3.
I thought the issue had to do with the XP install, but I still have the same problem. After I dock my laptop, my only option is to just "rip it off" the dock using the "eject" button which does nothing but physically detach the connectors. Its really frustrating more than anything.
really hard to google this also, since dock/button/undock are used in so many different contexts.
