I use extended warranty 3yr cc. Got it directly from an IBM/Lenovo reseller last year. It is to be activated 15 days post the completion of your official factory warranty as per the IBM service center. It can be done post the completion of your system's warranty as well. The guys at IBM just updated my product's serial number with that of the warranty pack online and it reflects on their system. Contact your IBM service center for details. IBM still handles after sales support for thinkpads atleast the X,W,T,L,SL series. I don't know about the edge series. Anyways thinkpads are one of the world's best built, most reliable systems and don't need extended warranty.
