Processors are usually soldered in for laptops and from what I've read about the S1 socket (which is the one your CPU is) they are embedded. You're unfortunately stuck with what you've got. If you want more performance I would try upgrading the RAM or perhaps getting an SSD. If you're trying to game on it, you're out of luck since GPUs are also embedded. But if you just want some everyday performance boosts an SSD and/or RAM upgrade should be a night and day difference.
