T410 - No video from external docking station video ports until Windows boots

[RLatND]

One of my T410 PC's has a problem where when it's in the 4338 dock, no video will be displayed on an external video ports until Windows has booted.  This means that you can't see the ThinkPad BIOS screen, etc. unless you open the lid.

I tried changing the video settins in the BIOS to set the DVI Display as the default startup display, but for some reason it doesn't even give me that as a choice.  It only gives the choices for built-in display, build in VGA output, and built-in Display Port.  On our other T410 computers it gives the choice for DVI when it's in the dockin station.

Any ideas?

Hello mate,

Is the BIOS version the same as the others ?

Inthe BIOS "Digital on Thinkpad" is DisplayPort on your computer. "Digial 1 on dock" and "Digital 2 on dock" are DisplayPort or DVI on dock.

The BIOS is not giving me the option to choose Digital 1 on dock or Digital 2 on dock...those choices simply aren't there to chosse from...they are completely missing.  It only gives me three options, Built-in, Analog, and Digital on Thinkpad.

Yes, the BIOS version is the same as the others.

That's strange...

I have exactly the same problem with my T410. Is there any solution for this? I also have no option for display port 1 or 2 in my bios.

I also have the same problem.  I have a T410 running bios version 1.38.  Has anyone found a solution? Thanks
