I have a basic M1330 for over a year now originally configured with the lowest CPU available which is the dual core T5250 at 1.5 and 667. I want to buy and upgrade the CPU. Intel says the socket for teh 5250 is PPCGA478. When I run CPUID it says socket P(478). When I search for dual core mobile CPUs at Newegg, the socket options are P or 478. How do I know for sure which CPU to get?
