Abstract: Techniques for managing lower power states for data links are described. An apparatus may comprise a memory unit to store a device connection manager for a controller of a bi-directional serial link connected to a device. The apparatus may comprise a processor operative to execute the device connection manager, the device connection manager operative to read a register of the controller storing information indicating an interface of the controller for the bi-directional serial link is operating in a lower power management state, send a control directive on a periodic basis for the interface to transition to a temporary active state, and receive an interrupt from the interface indicating the device is disconnected from the bi-directional serial link during a temporary active state. Other embodiments are described and claimed.
