I follow your instruction. Everything was ok, checked with OpaToolv0.8 got result as "machine is permanently activated". However, after Windows update, it came back to "3 days to activate" although the laptop still have Slic 2.1. Any idea what was wrong and how to fix it?

Thanks, could you please tell me where to get the certificate. I used your mod BIOS for T400 found at page 972 of thread 7500 on mydigitalife (I can not post link yet) I found this thread No. 10370 having SLP key, they all seems to be valid. I heard that certificate and key must match, is that true? I think I did something to insert certificate but can not recall exactly. Too many things happening now.
