T430 with Sandy Bridge

[ohitsanazn]

I have seen a couple of T430s on eBay with i5-2520M processors. These would be Sandy Bridge chips; is it possible to put an Ivy Bridge processor in place or does the entire motherboard need to be replaced?

You can put in an Ivy bridge processor without issue.

EDIT: If you are refering to a T430, then yes. If you are referring to a T430s, then no. The 's' models have their cpus soldered, so you would have to get a new motherboard with the cpu you want.
