no. laptop is not upgradable. you can only upgrade the memory and HDD. unless you wanna mod it (modding the laptop is upgrading the CPU and Video card although you do it at your own risk because it might damage the motherboard.)

mainstream laptop like that normally only allow you to upgrade the RAM & HDD. nothing more.

Looking through some specs for that laptop and I have not found any way that it can be upgraded apart from extra RAM. You can use an External GPU but the laptop must have a ExpressCard slot, unfortunatly yours does not. In most cases the CPU is soldered into place and again looking online it doessnt look like your CPU can be upgraded either.
