Abstract
Waking a computer from a system state. A wake data structure enables a device to wake the computer from a sleeping state. The lowest system state is identified that allows selected devices to still wake the system based on the contents of the wake data structure for the device. A chosen device power state is selected for each of the devices within the computer system and each device is placed within their respective chosen device power state. Wake devices have a particular chosen device power state that supports that wake device's capability of waking the computer system. Other devices are typically turned off. Finally, the operating system turns off any of power resources within the computer system that are no longer used by any of the devices.
