I’m not sure what the question here is. Are you wondering which level of suspension you want your laptop to go into when you close the lid?
You should understand ACPI sleep states when trying to setup whatever active states you want your machine to be in when you close the lid, because there is a chain of events that happen when you do so. Your machine may only support one, or a few states (s0-s3) that may not allow this. The first step is above, and the second is understanding what state your machine is being put into once you close that lid, so start there with Mint configuration and how it’s dealing with the lid closing.
