Problem with docking station.

Hi All, I bought a lot of docking station to our T61 and T60 Lenovo.

After that we can only turn off the notebook (4s put the I/O).
The problem occurs on the station type 2504 07/07, 07/06, 07/01
But on the station with 2504 07/04 is ok. I can unplag the power suplay and nothing happend.
Do you know what it is?

Re: Problem with docking station.

I would undock BEFORE removing the power supply. The docking station needs external power to work properly. It's not going to run just off the battery of the notebook.

This sounds like normal operation to me.

Re: Problem with docking station.

I haven't tried to unplug the dock power while running. But in the past versions (like A31 types) it would just revert to laptop mode and the pc would continue to run. Yes it didn't power anything in the dock, but the system kept going. I'd expect that type of behavior in the current versions too. Basicly you have an internal UPS for the system. Granted I run an external UPS for the whole docked setup, just in case.

Re: Problem with docking station.

Unfortunately I have not got UPS (why should I have – I have the battery ;-))
In my company the power is switched from time to time.
So, I need to find any other solution. The support of Lenovo is expensive. I think I ask some partners to help.

Re: Problem with docking station.

Hi ppawlo ,

There is new BIOS update that fix this problem. I has same issue at my job but this fixed problem.

Version 2.10-1.08

[Important updates]

[New functions or enhancements]
- Microcode updates of the processors.
- Added the new BIOS Setup option to avoid system hang even if the AC
adapter is removed from the ThinkPad Advanced Mini Dock while the
computer is attached to it.

*How to enable:
Set the Legacy Devices on Mini-Dock option to 'Disabled' of Docking
Station of Config in BIOS Setup menu.
A serial and a parallel port on the Mini-Dock will be disabled with
this setup.
