Abstract:
Method and apparatus for controlling power consumption of a plug-in card or circuit module (104). Power to a circuit module (104) is controlled by a user interface (116) and power manager (114) to automatically control the power state of the circuit module (104) by, among other things, powering the module up or down using a simulated hot unplug of the module (104). The apparatus further includes use of an I/O interconnect (126) to allow the system BIOS (122) to simulate the hot unplugging of the module (104).
