Your date of manufacturer is before the nVidia problems were fixed, but it's a date that has a low failure rate, and your problem doesn't seem to be consistent with a typical gpu failure, so this may be good news.
I can see that your computer is failing to go into hibernation, but you say that's only one part of the puzzle/problem, the main problem is the screen randomly shuts off, correct?
One thing you can do is try running the computer on a Linux liveCD boot disc. I'd recommend ubuntu (ubuntu.com). Get and burn the disc and start from it electing not to install, just to try it without making any changes to your computer. If you can run the computer sucessfully without this problem using Linux operating system, then it's safe to say you have a software problem and dispite your efforts to reinstall the effected programs, it's not fixed the problem. If the problem exists in linux too, then it would be hardware related.
I'm also eager to hear what other member may feel the problem is too.

Since you've determined this is a software problem, the easiest way to fix it might be to reformat and reinstall windows. If you do, the first thing I'd recommend doing is to run system update, this will install all lenovo drivers and updates, then confirm everything is working. If you let windows update install the drivers you might end up with something thats not 100% compatible. It's hard to say what went wrong here, but starting over would be easier then trying to sort out the cause.

I have t61 08/02 whats the failure on that time frame. relative of course....
Your date is February 2008, which is about when it's believed nVidia was re-engineering the GPU design. The best evidence suggests the updated chips followed shortly after your unit was built, but the old design wasn't eliminated until August 2008. On an 08/02 I'd say it's unlikely to have the improved chip, even if some were shipped in February they wouldn't have made it into a laptop that fast, but there really is no way to know because nVidia won't even admit the bug exists. I wouldn't be overly concerned about it though, millions of these units have been in service for over 4years and probably will be for years to come, the actual failure rates are small, but it's the costs and the difficulty obtaining reliable replacement boards that make the problem significant.

HEELP, PROBLEM IS BACK
After succesfully using sleep and hibernate for two days I now have the same problem again.
I put the computer in the dock and tried to hibernate and nothing happened (the screen turned black, speakers turned off, the wifi, battery, power lights were on).
What could have happened in two days that made the problem reveal itself again?

perhaps automatic updates?

no i had set auto update to never update again.
BUT however after formating the computer yet another time and installed every update out there from lenovo and microsoft I did get it to work. sleep mode worked every time until today. I had probably set the computer in sleep mode 5 times this day (the computer sleeps by it self after 15min on battery). Then all of a sudden the problem was back without no warning. I have not done anything except writing in a word document from the time it worked until the time it stoped working again.
Anyone smart out there who can figure this out. It seems like its hardware failure but it all works in ubuntu and sometimes in windows so should be software problem right?
