Power management method and device for display devices

Abstract

The positions of a mouse pointer and of an active window, as well as the operating state of a keyboard/mouse, is used to determine the power state of each display in a multiple-display system. A system in accordance with the preferred embodiment includes only one of each of two resources (an active window and a mouse pointer). The positions of the resources on a plurality of screens are determined, and when they have not been displayed on a specific monitor for a specific period of time, that monitor is moved to a low power consumption mode (a low power operating state). Since, when a user of a system using multiple monitors is creating a document with a word processor, only one monitor is normally required, other monitors may be put in a low-power state, even though full use is being made of the keyboard/mouse.

Dependencies are inferred from the claim text.
