Windows 7 - HP 6450b - Issues With Advanced Docking Station

I work for a school system and we're looking at going to Windows 7 x64 Professional soon for administrators (not teachers or students). In our testing, we have three users in our office that are using HP ProBook 6450b laptops with HP Advanced Docking Station as their only workstation. This will be the same setup that a lot of users will have as well once we deploy it further. These three users all have issues when placing their laptops on the docking station. Two of the three usually have their laptops sleep when leaving home and get prompted to repair Windows once it's placed on the docking station and turn it on. The other I can't get a straight answer out of but claim that they turned it off every time they're done.

When the two users get the repair menu, one lets it repair and her laptop's fine. The other cancels the repair (all data is not on the laptop and we can re-image it if anything happens) and his laptop's fine once it's in Windows.

Both users that have the issues are now running SP1, which made no difference with or without. One of the users had the HP drivers for the Advanced Docking Station installed, which seems to just add USB drivers. One user we've swapped out the docking station for a new one. We've even tried BIOS updates. No matter what we've tried, the errors still occur.

I've tried to find specific information on the issue with that model, but haven't been able to. When I've searched for "docking issues" with Windows 7, I keep finding suggestions to modify the registry to add the "undock" button to the Start\Shut Down menu but I believe it is specific to Vista and does not work for my test unit.

Any suggestions? Is this a known issue with some docking stations and Windows 7? We just want to get this straightened out before going out to more users. Thanks.

Earlier I posted asking about anyone knowing of issues with an HP 6450b laptop and docking station. No one replied. So, now I'm asking if anyone has had any similar issues with any laptop/docking station configurations.

Well...I really thought I was the only one to have issues with my HP Docking Station since I upgraded to Windows 7. did you find a solution?
my problem is only with the USB ports. the rest works fine.
I read in some forums about drivers to solve the problem. what I wonder is where they actually found them.
