I recently purchased this laptop and noticed that it uses the Intel HM76 Express Chipset, which means it is upgradeable to a few Core i7 CPUs that comply with Socket G2 specifications. However, when I called Toshiba support to confirm this, a representative said the current CPU - an Intel Core i3 2370M - is embedded and therefore cannot be upgraded. I'm not sure if he was entirely sure what he was talking about. Does anyone know if this is true?
