Question about IBM ThinkPad T40 2373 Notebook
This is a known issue with the T40 series. I have the same problem. It's a result of a manufacturing defect introduced through a new soldering process Lenovo used on this series. Basically, they baked the motherboard in an oven instead of soldering the components on one by one. This resulted in many of the graphics chips not fully connecting. After normal use, a corner can pop up, causing the screen to go blank if you move, lift or jostle the laptop.
As far as I know, Lenovo doesn't offer any fixes for this. If you wish to risk it, you could try soldering the loose corner yourself. Some people found a wedge works well. I stuff carboard between my keyboard and the chip to keep it down. Other people hve been known to use post-it notes.
