i have a Thinkpad T42. I can boot in up and log in just fine. However, once I have logged in, anytime I bump the side of the laptop or put pressure on the area for your palms, the monitor shuts off and I cant recover it. The only way to continue is to force a shutdown. Note: The monitor doesnt always turn off. sometimes when I hit it or put pressure, it is fine, other times it shuts off.
