I can confirm this with up-to-date Natty. You might not want to remove the battery when running a 2.6.37-rc6 based kernel, as this can cause a system crash/oops: https://lkml.org/lkml/2010/12/19/90
To reproduce, I simply boot without the battery attached and then attach it while running. ** Changed in: gnome-power-manager (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/675108 Title: gnome-power-manager adds battery to indicator twice when battery hot-unplugged and plugged back in -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
