By the way, on the japanese lenovo website Bios Version 1.20 is available already for the T400. Maybe this will fix the issue. I will try it as soon as it is available on the international website or via system update.

Re: T400 Dock Problem

2008-12-19, 2:30 AM

Well, I've updated the BIOS and the new video driver (using system update 3).  Thought it would resolve the switchable graphics problem.  I changed the BIOS display setting back to factory (switchable not discrete and system detects the graphic card). 

 

After rebooting, it seems to only give me the Intel video option.  The ATI is not available even with the power setting set to max.  I changed the bios setting back to discrete and disabled the switching. 

 

Is there any suggestions on how to fix the problem.  Initially, I just wanted the system to recognize the DVI port so I can use my 24 inch monitor as my primary.  Now I've given up and I have both monitors open.

 

Thanks.

Re: T400 Dock Problem

I just updated my T400 to BIOS 2.07-1.01 but I still can't enable DVI as boot display when switchable graphics is enabled. Is this still not fixed or it a problem of my machine? And what does this mean:

"(Fix) Fixed an issue that could not select Digital Display(DVI) from Boot Display Device of Display of Config in BIOS Setup (Integrated graphics models only)"

There is nothing mentioned about switchable graphics but instead integrated? I thought intergrated one is not connected to DVI.

Can anyone help?

Another switchable graphics T400 user here, seeing no boot to DVI option in the bios when in switchable graphics mode. But i guess it wasn't promised in the description. How did you get it to work edgmiw?

Manpacker,

Truth be told, I updated the bios but have simply left my system in the discrete graphics only mode avoiding switchable.  This was the solution prior to the release and since I wouldn't use integrated graphics anyhow, I've just left it this way.  It works properly this way but you will have to reboot and enter the bios twice.  Once to choose discrete graphics only and then again to actually get it to recognize the DVI option once discrete only is enabled.  Good luck!

I have a similar issue and was hoping to get some clarification for my problem.  According to the release notes for BIOS version 2.07, it appears that the DVI issue is fixed but I'm not seeing it work.

 

  • (Fix) Fixed an issue that could not select Digital Display(DVI) from Boot Display Device of Display of Config in BIOS Setup (Integrated graphics models only).

Ok, my machine info follows:

 

  • 7417-CTO (Vista Basic)
  • BIOS version 2.16
  • Docking Station (one I got for my T61p, I don't know the model number, can find out)
  • Intel Graphics Media Accelerator 4500MHD - is my graphics unit

When I power up with the T400 docked, the video only shows on the LCD screen.  In the BIOS, I have it set to DVI (from the LCD/VGA/DVI selection) and Internal for the boot display (from Internal/PCI Express selections). 

 

From within Vista, when I try to output it to an external monitor, it complains that there is no detected external monitor.

 

Are there some docking stations that work for the T61p that won't work with the T400?

Does my graphics unit work with DVI output on a docking station?  (I've only see this mentioned in the context of a switchable GPU - Ati/Nvidia/integrated.)

 

Thanks a lot!
