Particular embodiments described herein provide for an apparatus that includes a means for determining a power state for a device connected to a system, a means for determining that the device should change power states, and means for sending a signal to the device to put the device in a D3-cold state while the system is a GO/SO state. In an embodiment, the device is a peripheral component interconnect (PCI) device. Also, the particular example implementation can include means for sending a WAKE# signal from a controller to the device to cause the device to exit the D3-cold state, wherein the WAKE# signal was sent from a designated WAKE# signal pin on the controller. In some embodiments, the WAKE# signal is not sent to other devices in the system.
