My computer won't go to sleep under Fedora 30

Yesterday I wiped two of my computers, a MacBook Air and and dual-graphics MacBook Pro, and I’ve been setting 'em up since then…one issue after another.

Neither of both will go to sleep when I close them, even in Windows they’ll go to sleep but not in Fedora. I’m new to Linux in general so I don’t know how to diagnose but I still tried journalctl -xe > randomfile to get the output after closing every app en closing the lid on one of them and I got:

Obviously it makes little sense to me. I’ve observed the computer runs crazy hot, I’m in a freezing room with a couple of tabs open in Firefox and the fans are at full blast, it was actually worse and casual scrolling through an Amazon.com page was stuttery but after installing the Nvidia drivers it went down just a little. At least it scrolls smoothly now.

Any ideas? Thanks !
