In many cases the full capabilities of a system might not be required. This allows the system to be responsive to the user, yet energy can be conserved during the time period that a working state is not required. If a working state is not required, the system power state can be changed from the working state to a sleep state and, subsequently, quickly changed back to a working state as required. Reducing system power consumption results in lower energy costs and longer battery life. To effectively manage power, the PC software, hardware, and Windows must work together in a framework that enables every device to be power managed in a consistent manner.Ī PC configuration that takes full advantage of the Windows power management architecture, provides the following advantages to users:Įnergy savings and extended battery life. To meet these ever-increasing user requirements, Windows must be able to manage the power that is used by any device in the system, including add-in boards such as graphics cards, network adapters, modems, and sound cards. Users with computers hidden away under desks want to be able to turn them by pressing a button on the keyboard or monitor.Ĭustomers want to decrease the amount of power and total energy that a PC uses, whether the power comes from an electrical wall outlet or a battery.

Microsoft Windows supports a power management architecture that provides a comprehensive approach to system and device power management.
