Abstract
A BIOS controlled peripheral device port power device is described. The device includes a processor and at least one peripheral device port. The processor powers up a host controller in preparation for the processor to enter a sleep state. The processor also places the processor in the sleep state after the host controller is powered up. The processor also selectively powers the at least one peripheral device port by the host controller when the processor is in the sleep state according to at least one setting stored in the processor.
