PGA988 Compatibility

[Blaze200038]

I recently came into possession of a Samsung Np300E5C-AOCUS.  The previous owner broke the power jack, got a new one, and put it under their bed until I offered to take it off their hands.
Initially, I was going to just scrap it for its hard drive, DIMM's and copper, when I became acquainted with the PGA988 socket lurking inside.  Now, I've never been a fan of laptops (I hate batteries, I really do) but the idea of making this into a machine that I can bring with me on the go do so some hardcore web browsing is actually pretty appealing.

 

So, how good is PGA988 compatibility across the board?  The stock processor is a Pentium B950, and I'd like to replace it with something a bit beefier- say an i5 2540M or i7 2640M.  Both have the same TDP, and both are Sandy Bridge (like the B950) so what are the odds that they'll be compatible?  Without being able to power on the system (waiting for replacement power jack to arrive before I can do the repair) is there anything I can do to verify compatibility?
