GNOME Power Manager
is a daemon that is installed as part of the GNOME desktop environment. Much of the power-management functionality that GNOME Power Manager
provided in earlier versions of Red Hat Enterprise Linux has become part of the DeviceKit-power
tool in Red Hat Enterprise Linux 6, renamed to UPower
in Red Hat Enterprise Linux 7 (see Section 2.6, “UPower”
). However, GNOME Power Manager
remains a front end for that functionality. Through an applet in the system tray, GNOME Power Manager
notifies you of changes in your system's power status; for example, a change from battery to AC power. It also reports battery status, and warns you when battery power is low.
