I've got a IBM Thinkpad T60 (still branded IBM, but essentially a Lenovo) with a Core Duo CPU T2400, 1.83Ghz, Yonah, Socket 479 mPGA. Is it possible to upgrade this laptop to a Core 2 Duo? Given that there are other T60's that support Core 2 Duo, I'm guessing "yes". Only difference is the FSB: mine says it's runnign at 666Mhz and the T7300 that i'm keen on is FSB800. My motherboard is a i945PM. Memory is all DDR2, running at 333Mhz... so 667Mhz DDR.
