Abstract: PROBLEM TO BE SOLVED: To reduce power consumption when a computer with a mini PCI card or a device corresponding to the mini PCI card inserted thereinto is in an inactive state. SOLUTION: An I/O bridge 21 for outputting inactive information about whether or not a computer system is in an inactive state and a Vaux off at sleep resister 42d holding information about whether or not to feed auxiliary power VccAUX to a mini PCI device 60 when the computer system is inactive, are provided. When a signal from the I/O bridge 21 is L and a signal from the register 42d is L, the feeding of the auxiliary power VccAUX is stopped from a DC/DC converter 55.
