I am sorry but there is very little you can upgrade on a laptop. You can add memory or a larger hard-drive but the main components,the processor and graphics card you cannot upgrade except for some high spec and expensive gaming laptops. Your laptop is very basic so you might struggle.
You can try this Can you run it. but it does not list Elder Scrolls online yet but it does list Elder Scrolls etc. This will at least give you an idea of your laptops capabilities.
