What you're looking at is an usual set of symptoms for GPU detachment which is an extremely common problem on T4x units.
Three fixes: a) Replace the system board b) Re-flow the board yourself c) Replace the board with an Intel based board from R51.

I ran it instead on an external monitor which seemed to be great. However when I ran it today neither the LCD or external would show bios or OS screens. Just this mess. http://imageshack.us/photo/my-images/535/img0002wfw.jpg/ At first I could tell the screen had gotten to the windows user prompt since mouse and keyboard commands were working. However I'm not so sure anymore after multiple reboots. Is this old t40 repairable? On Wed, Aug 24, 2011 at 10:00 AM, <[email protected]> wrote: > Send Thinkpad mailing list submissions to > ? ? ?

Called to verify this, they said it would be. Ordered it, and it was: came in the usual "PC Options" box with Lenovo barcodes and Lenovo security seal tape.
