I have a Dell Latitude D830 laptop with a port replicator/docking station. Today when the user docked and logged in the monitor was flickering and the keyboard num lock/scroll lock was flashing. I disconnected the keyboard, shut down the laptop, and unplugged the power cord from the port replicator. I re-plugged the power to the port replicator, plugged in a new (out of the box) keyboard and rebooted the laptop in the port replicator. When it booted to the desktop, nothing connected to the docking station, except the external monitor worked. I had no LAN connection, keyboard or printer. I tried a different port replicator and got the same result. I powered off the laptop, undocked, and connected all cables directly to the back of the laptop and everything worked. If I go to My Computer, Properties, Advanced, User Profiles and I delete the docked (or any listed profile) will that delete the user profile in Windows XP? Or is that just the hardware profile? This user has many customized settings on this machine and I do not want to delete their Windows XP profile; for example they use Outlook and they have many custom views setup, if I delete the docked profile will it affect her Outlook settings? Also this laptop is connected to a domain so when they login they are using their domain username and password.
