I ran into a similar problem (bug 120258) with incorrect discharge time shown. For that, it was resolved as follows: In gconf-editor, set apps->gnome-power-manager->use_profile_time to FALSE (unchecked).
It was reporting my discharge time as much less than real (55 min instead of 4+ hrs), and after the 55 min passed, I started getting notifications similarly to what you described. After applying this gconf change, the popups went away. Could you check and see if doing this resolves your bug as well? -- Wrong message information under the popup notification https://bugs.launchpad.net/bugs/66131 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
