I have a Lenovo Carbon X1 that is a few years old (7th gen), and I am running Fedora 38.5 with GNOME 44.5. The issue is that the system does not sleep properly. If I close the lid, nothing suspends properly, so if it is not on a charger or shut down it will die within several hours in my bag. Are there any distros that handle power management and suspend status on this hardware better than Fedora?
Did you check if there is a bios setting related to suspend, and that it’s set properly?
