Hey there, Bevso.
You should have information on how to upgrade the laptop's HDD/SSD in the User Manual (although as it turns out it depends on the model and manufacturer, as some manuals don't include that info). If you can share the image and/or the model of the laptop it might be easier to find the information you need.
You could also look it up on the web, or get in touch with the laptop manufacturer's customer support for more info.
Hope that helps.
