There is no polling involved, ACPI battery updates come in and g-p-m status is updated.
Are you talking about the battery icon only having a limited number of positions? Can you do a screenshot showing what appears to be wrong for you? For example if hovering over g-p-m says '75%' but typing 'acpi' at the command line says '53%'. -- gnome-power-manager does not update often enough, only updates every 25% of battery charge https://launchpad.net/bugs/66025 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
