Problem solved in 14.04.1 when reverted to original kernel: $ uname -a Linux jjc-xps 3.13.0-44-generic #73-Ubuntu SMP Tue Dec 16 00:22:43 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Problem happens when using updated kernel also in the repositories: Linux jjc-xps 3.16.0-29-generic #39-Ubuntu SMP Tue Dec 16 20:54:13 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux So problem may be kernel-related or upower/gnome-power-manager not understanding new kernels. Previous report was generated with 3.16.0-29-generic #39. People with 14.10 may try to boot with a 3.13 kernel and report here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1391555 Title: Bluetooth mouse battery reported as "Extra" battery To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/1391555/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
