Comment 2 for bug 462267

Thank you for your bug report. However, the applet was removed deliberately because it uses deprecated technology (see the discussion here: https://lists.ubuntu.com/archives/ubuntu-desktop/2009-August/002183.html)

The applet uses the obsolete /proc/acpi interface (which is often incorrect and a source of bug reports when the battery status doesn't match what is expected) or HAL (which is also being deprecated as well, and the power functionality replaced with Devicekit-Power instead) for obtaining battery status info. Fedora haven't shipped this for some time either.

If there is functionality missing from g-p-m, it would be better to add it there rather than maintaining obsolete and buggy software which pulls in undesirable dependencies.
