Lenovo T420s Docking Station problem / Loose Connection

Hi Everybody,

I have a very strange problem with the Lenovo T420s series.
If they are in the Docking Station and I push (very little, very soft) on the left upper corner, the laptop is losing connection for a moment. The mouse and keyboard aren't working anymore.
This is also happening when somebody is typing a little strong and the Docking Station is on the table. I have this problem on Windows XP as well as Windows 7 laptops. It's happening on 5 different systems. But all T420s Systems. I have changed a couple of docking stations, and it's happening with brand new Docking stations as well. Is there a general Problem with this series and Docking Stations? I really never had any issues with lenovo and I'm a big fan, but this is pretty annoying...

Thanks for any suggestions and help in advance.

Cheers, Pascal

Just some guesses...Make sure the male and female contact ports are clean and make sure the laptop is secured all of the way in the docking station.

It sounds like a loose or bad connection.

I've seen the same thing happen with HP docking stations.  My users complained and said it was secure until I lifted the laptop off without having to disengage.  After that they made sure they were docked fully.
>>  it's happening with brand new Docking stations as well.   <<   i would contact the seller, and ask for warranty repair/replacement

I'll contact the vendor now. But I assume this will take some time so I'm closing the ticket for now. If I should however find out more I'll post it here anyway.

Thanks for your comments.
