Abstract:
1. A computer-implemented method comprising: establishing a network state for the computer, wherein the network state will expire in a set amount of time; setting a maintenance timer to expire prior to the expiration of the network state; placing the computer in a sleep state without terminating the network state, wherein placing the computer in a sleep state includes powering down a fan controller, wherein the fan controller includes processing logic that determines, using information from temperature sensors, whether to turn a fan on or off; powering up select components of the computer from the sleep state at the expiration of the maintenance timer, wherein the select components include a network interface, the fan controller, and a processor core and wherein the select components do not include a display, human interface devices, and audio components; renewing the network state; and powering down the select components of the computer to return the computer to the sleep state, and wherein the fan controller receives power during the renewing of the network state and receives no power during the sleep state.
