How to replace backplate made of glass?

The backplate of glass is shattered, but i dont see any screws. I assume its all glue under with glass ontop sealed. Will it be easy to repair this or is this a harder job than typical cellphone’s with superglue today? Currently having this laptop in for repair at our it-department. Unsure on how to go on, google didnt exactly help with the issue and no results where found to replacing the back-plate.
