In Fedora 11
DeviceKit-power assumed the power management functions that were part of
HAL and some of the functions that were part of
GNOME Power Manager in previous releases of Fedora (refer also to
Section 2.7, “GNOME Power Manager”. In Fedora 13,
DeviceKit-power was renamed to
UPower.
UPower provides a daemon, an API, and a set of command-line tools. Each power source on the system is represented as a device, whether it is a physical device or not. For example, a laptop battery and an AC power source are both represented as devices.
