UPower (previously DeviceKit-power) is a piece of middleware (an abstraction layer) for power management on Linux systems. It enumerates power sources, maintains statistics and history data on them and notifies about status changes. It consists of a daemon (upowerd), an application programming interface and a set of command line tools. The daemon provides its functionality to applications over the system bus (an instance of D-Bus, service org.freedesktop.UPower). PolicyKit restricts access to the UPower functionality for initiating hibernate mode or shutting down the operating system (freedesk
UPower (previously DeviceKit-power) is a piece of middleware (an abstraction layer) for power management on Linux systems. It enumerates power sources, maintains statistics and history data on them and notifies about status changes. It consists of a daemon (upowerd), an application programming interface and a set of command line tools. The daemon provides its functionality to applications over the system bus (an instance of D-Bus, service org.freedesktop.UPower). PolicyKit restricts access to the UPower functionality for initiating hibernate mode or shutting down the operating system (freedesktop.upower.policy). The command-line client program upower can be used to query and monitor information about the power supply devices in the system. Graphical user interfaces to the functionality of UPower include the GNOME Power Manager and the Xfce Power Manager.
UPower is a product of the cross-desktop freedesktop.org project. As free software it is published with its source code under the terms of version 2 or later of the GNU General Public License (GPL).
