Typically, however, devices lose little context upon entering this state. The specification for a bus or device class that supports D1 typically provides detailed requirements for preserving this context.ĭrivers must save and restore or reinitialize any context lost by the hardware. In general, device context is preserved by the hardware and need not be restored by the driver. Typically, the specification for a bus or device class that supports D1 describes this state in more detail. Frequently, D1 is a clock-gated state in which the device receives just enough power to preserve the device's hardware context. It has the following characteristics:Ĭonsumption is less than in the D0 state but greater than or equal to that in the D2 state. The following sections describe D1, D2, and D3:ĭevice power state D1 is the highest-powered device low-power state. Many classes of devices do not define these states. Starting with Windows 8, D3 is divided into two substates, D3hot and D3cold.ĭ1 and D2 are intermediate low-power states. Device power states D1, D2, and D3 are the device low-power states.
