Hi abhay5104,
Thank you for considering Sony Community!
Before upgrading the memory (RAM) of your laptop, it is advisable to check the maximum capacity it can handle. We also suggest using parts from Sony Authorized dealer of Parts and Accessories to limit any possible issues. VPCEH35EN is an Asia-Pacific model. Unfortunately, we do not have the complete details of the specifications and compatibility of the parts and accessories.
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,
Vincent
