The I5-2430M is a notebook processor (either Socket G1, or soldered to the motherboard). If it's socketed, you'd need to find another notebook CPU to replace it. An I7-3770 is LGA1155, a desktop socket, completely incompatible.
There are mobile quad core third generation I7 CPUs like this one:

This isn't a recommendation. There are a number of things that could prevent the upgrade. One, your current CPU may be soldered to the motherboard, making it almost impossible to swap out. If it's socketed, your motherboard may not support a swap from a second generation I5 to a third generation chip. (I don't know enough about mobile sockets to guess whether that for the I5 and I7 are compatible.) Your current CPU is rated at 35W; the I7, 45. That's not a huge increase, but the laptop may not be able to handle it.
