Thinkpads have very good advanced diagnostics. If you don't have manuals telling you how to access them, check out IBM's website (even a google site:ibm.com ) using your machine number (the four-digit IBM number not the sales dept's Z61M. You should be able to find the service manual for it which will tell you how to run the advanced diagnostics.

It is those diagnostics that IBM will run to determine a warranty claim. The manual tells them which FRUs to swap out until the diagnostics tell them that the machine is good.

Good luck.
