Saw exactly the same think on another t41 i was trying to fix. If it was moved at all screen went off.
Turned out it was corrosion on the motherboard that was causing the problem.
Has it been liquid damaged or got damp in the past?

Cold boot the machine, press F1 to access the bios. There is a setting for "screen blanking" which you need to turn off.
If that isn't the problem, you have a short in the keyboard I'd say.

I assume you have verified the battery and AC adapter with another machine or a voltmeter.
If none of the above get it going, you most likely have motherboard issues, possibly a blown fuse.
Or possibly a keyboard Power On switch problem.

If prior to this it works intermittently with the AC adapter, it means the connection from the adapter power unit to the motherboard was lost and this is a typical problem with the Thinkpad. It needs a re-soldering job and not something that one can do without a proper repair manual on how to open the laptop. Try googling your problem and find out if someone has the same experience and managed to resolder by him/herself.
