HP Probook 6450b freezes when undocking station?

Hello, it has been reported that a user of a HP Probook 6450 always experiences that the laptop freezes when undocking from the dock station, and is forced to restart the computer.
I have done some investigation on the net that suggests that the problems might be that dockstations and laptop uses different drivers, but so far I have not found any suggestion in how to remedy this problem?

try updating the drivers for the laptop, and docking station

Is there any chance he is doing something dumb like leaving Outlook, IE, or having anything open from a network share when he undocks?

there might be some updated HP drivers for hot-undock and perhaps for power management/chipset or NIC drivers -- though that model is about 3 years old now, so HP won't be updating much for it, maybe NIC drivers & BIOS, always worth checking if any BIOS updates address such freezing issues.

how are they undocking, live while still on windows (hot-undock) or after hibernated/suspend to disk??

laptop may freeze if something is actively using the network when it gets undocked.

I assume the laptop is Win 7 Pro 64bit??
