How do i unlock 4338 docking station, laptop will not seat

SOURCE: removing laptop from docking station

If you have the ArmadaStation EM:

The issue of removing the notebook is compounded by the fact that the ArmadaStation EM uses a motorized dock/undock mechanism to remove the notebook. When the expansion base has no power, it is unable to eject the notebook with the motor

To manually remove the notebook, use manual eject lever to push notebook out of ArmadaStation EM. The manual eject level is a small white lever located inside the back cover of the base. To remove the notebook, push the white lever to the left. Slight pulling is required to remove the notebook completely out of the base.

Hope this helps!

You will have to take the docking station apart until you can see the locking mechanism. Once you can see the mechanism, you should be able to get a screwdriver ron it and release it. Make sure that it releases, don't force it, and most of all, be patient.

I have the same docking station and I am typing this on my T60 right now. I have noticed that sometimes it is very hard to dock my laptop and other times it just slides on instantly. This seems to be an issue with poor design. If you look a the dock connector under you laptop you will notice there is a strip of plastic in the middle of two rows of connectors. The docking station connector must be perfectly aligned to successfully connect. I would inspect it for any damages, but honestly I think it is just an issue of patients, precision and a little bit of luck. If you can not identify any damage I would just slowly try to line it up and keep trying until it clicks. Remember to never force it and once it lines up it will slide in with very little force.

The solution that resolved this problem On Bios version F.0E was:

• Power up the unit off the docking station and plug it into the docking station.
• Delete all copies of the COM1 port in the device manager.
• Perform a restart on the docking station.
• When you log back into windows go back into the device manager and redetect hardware.(You should now have 2 visable copies of the COM1 port. One will have a bang next to it.)
• Delete both copies of COM1 and scan for hardware changes. (This should give you 1 good copy of the COM1.)
• Power down the laptop, and take off the docking station.
• Power it back up straight from the docking station and you will notice no more hangs when booting off the docking station
