Hi Kvanubhav,
Welcome to Sony Community!
I'm afraid, it's not a good idea to upgrade the processor of your laptop because when you replace it, you might need to replace everything like the hard drive, memory, etc because they are all meant to work with the currently-installed processor Plus, you might have issues with the drivers and software. To prevent any unforeseen issues, we recommend that you stay with your current processor or consult a professional technician or go Sony service center in your area.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
Regards,
Jen
