Sorry for late reply and thanks a lot for your help.
Which RAM and SDD I need to buy to upgrade ?
I figured out that this [https://www.wdc.com/products/solid-state-drives/wd-blue-ssd.html#WDS500G1B0A|ssd] is compatible with my laptop , Please correct me if I am wrong ?
RAM I am not sure, if you don't mind can you please let me know the amazon.com US url for compatible RAM.
