Hi hasrat,
Welcome to Sony Community!
We don't recommend modifying this laptop. When you upgrade some parts there is no guarantee that it will work. It may or may not work.
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
