OK so basically powertop just doesn't work on this laptop. It appears it doesn't realize it's running on battery. gnome-shell and upower knows it's running on battery, but powertop doesn't report the wattage being used by the battery, or a time remaining estimate. On another (older) laptop with identical kernel and Fedora 25 updates, powertop does have this information from the battery, and it's successfully writing out to saved_results.powertop file. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
