Hi Farie977,
Welcome to Sony Community!
We don't recommend upgrade on any VAIO laptops because they're integrated with each other; we can't guarantee the outcome after the upgrade. In addition, replacing any parts might do more damage to the laptop.
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
