Public bug reported: something in the kernel probably broke powertop power estimate since 12.04, it's showing probably exactly 1/10th (rounded) of the actual estimate, compared to gnome-power-statistics:
Power usage (ACPI estimate): 0.7W (55.6 hours) (long term: 8.8W,/3.8h) g-p-s shows 6.7W at the same time ** Affects: powertop-1.13 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1295040 Title: power estimate shows one tenth of the actual usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/powertop-1.13/+bug/1295040/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
