Abstract
An instant-on PC is described which can be revived from a sleep state in a matter of seconds. This is carried out by keeping certain power-managed devices in a quickly-revivable state, e.g., the memory and certain elements on the motherboard chipset. Certain PCI devices are also enabled in a quick wake-up state so that they can wake up on a specified stimulus. The power consumption of each of these devices is obtained and it is determined if that power consumption exceeds the power capability of the auxiliary power supply. If not, the more aggressive sleep state is enabled. If so, however, the system takes action to either enter a less aggressive sleep state or to selectively de-enable certain ones of the devices that are in the keep-awake state. Preferably the choice of which to do is made by the user.
