I am considering upgrading my laptop CPU from an i5-2410M to an i7-2640M as I have seen one relatively cheap on eBay.

I don't believe this should be a problem as both require the same chipset, HM65 both require the same socket, PPGA988 (the current CPU is not soldered to the board) and both have a max TDP of 35W.

However I was then looking at third generation chips, specifically the i7-3520M, which also requires chipset HM65 but requires a slightly different socket named FCPGA988. Can anyone tell me the difference between PPGA988 and FCPGA988, if any? Would this mean that my laptop could not support the i7-3520M?

My current CPU:

The CPU I am confident I CAN upgrade to:
http://ark.intel.com/products/53464/Intel-Core-i7-2640M-Processor-4M-Cache-up-to-3_50-GHz

The CPU I`m not sure I can upgrade to:
http://ark.intel.com/products/64893/Intel-Core-i7-3520M-Processor-4M-Cache-up-to-3_60-GHz

Many Thanks, Alli.

A good point, I`ll have to look into that. However, my original question of the difference between socket PPGA988 and FCPGA988 still stands, I have emailed Intel and have had no response so far!
