t400 No Display AT ALL (either internal or external display)--MOBO Components

Hi folks!

After struggling with this problem 2 days ago: http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T400-doesn-t-boot-to-BIOS-MOBO-components/t...

 

Now I have a new problem: I have literally NO DISPLAY!

Either the internal LCD or an external LCD monitor provide NO output.

 

It seems like, judging from the HD lights, etc. that the system is booting normally. I'm able to boot into windows and, remembering key combinations, can shut down windows normally (Start key, U, U). So I think the system is booting up just fine. It's just that there is literally NO display.

 

I've even tried to wait until I"m in windows, then open up the display manager (I assume....FN+F7), then scroll down to other video output options to try and force it to use an external monitor....that doesn't seem to create video output, though I'm fairly confident I'm getting the Display Manager to try and switch...

 

Any thoughts? 

 

Thanks!

Hi ElSteve9,

This is clearly hardware problem, please contact local lenovo for hardware test.

I think this external monitor got resolution which you have to set in windows. You should try with a new display which can set resolution by it self or a display with good resolution for t400.
