Question Toshiba satellite c855-113 upgrade

[Eligijus]

I want to upgrade my pretty old toshiba laptop. Currently I have added SSD and 4 GB RAM. The CPU has a socket so i was wondering if i could replace my intel pentium B960 with a better CPU.
Let me know if it is possible. x)

This is a list of CPUs for that socket. http://www.cpu-upgrade.com/CPUs/Intel/Core_i7_Mobile/i7-640M_(PGA988).html

What will work with the specific laptop is a bit of a guess unless you can find online someone that did it, or read the BIOS version notes to see about CPU supports. At least all the CPUs are the same wattage so that is a good sign, but CPU support can still be iffy due to the fact laptops are not very standardized.
