So there is something you need to realize about Linux Mint. If you value privacy and security then you need to get off of it immediately. It is a shady distro that is not trustworthy.

Make notes and investigate all the connections it makes to discover why. Don't panic. If you need help finding a new distro let me know.
Second, which method of suspend are you using when you look in the system settings?
