I would typically target research the Mainboard for this one. Obtain the Motherboard part number, (I think it should be the standard intel i-core motherboard v000275070 ) find all references to that part. The pictures do show some models with the socket for upgrading as well as Toshiba did provide firmware that complements the Core i5-2450M. You best answer lies with Toshiba themselves. Contact support (Via chat) , give them the motherboard model number for your laptop , ask them about the chips and details if they support or ask them to send you details on the motherboard chipsets / bios. I am not having much luck on google for this one. Good luck friend!
