GNOME Power Manager is a session daemon for the GNOME desktop environment that makes it easy to manage your laptop or desktop system. Power management is an essential job on portable computers, and becoming more important on today's high-powered desktops. It uses many complex parts of the system - each of which is slightly different, and may contain quirks to work around. The power management policy could be influenced and tweaked by a huge number of options, and each new laptop model brings more possibilities and options. This should all work in the background without even being noticed by the user. GNOME Power Manager is written in C, and has additional dependencies of UPower 0.9.1, DBus 0.61, and libnotify 0.4.2.
