T420 Socket Type

[wswartzendruber]

What type of CPU socket does the T420 have?

[blackomegax]

Research tells me it should be socket G2

[jaspen-meyer]

Can someone confirm the socket type?

Is it a G2 or BGA-1023?

[axur-delmeria]

The T420 contains a socketed Sandy Bridge Mobile i5/i7 processor, G2 socket A number of fellow Thinkpadders have upgraded the processor in their T420--at times to a quad-core i7 Mobile---so we know this to be true.

BGA 1023 is for soldered Sandy Bridge mobile CPUs, and is used on the X220, as well as the T420s, which is the slim variant of the T420.
