Just to let you know, we only provide support in English language and currently, we are using a translation tool.
In this case, in order to gather the information you are looking for, the best thing to do will be to get in contact with Acer directly, they will be able to provide the details needed for you to know what can be upgraded in your laptop and the steps to follow for you to be able to do that:
