Finally I got my motherboard replaced at the repair center... But really have hesitation to try it again... X_X
odd, i have the 3.09 bios, the one for the t400 with firewire, the same one you listed you needed, and win 7 is still activated.
Really? I'll give it another shot tonight but as soon as I tried it yesterday and it deactivated as soon as I rebooted. Edit: Tried it again and it is 2.0 and deactivated.
