US Patent 7145559 Display device power savings

An electronic or computing device includes an integrated graphical display and a power source, such as a battery, to provide power to operate the graphical display. A selectable shutdown control, such as an operating system shutdown control, is displayed on the graphical display, and when selected, initiates a process to shutdown the electronic or computing device. The device also includes a component, such as a graphical display controller or software application, to turn off the graphical display and conserve power when the selectable control is selected and before the process to shutdown the electronic or computing device is initiated.
