Deeper Sleep is functionally identical to the Deep Sleep State but at a 66 percent lower voltage.Įxtends battery life by entering a low-power state during the briefest pauses in user activity, such as between key strokes. It reduces processor voltage below the minimum operating voltage while preserving the processor state. It reduces power when idle and quickly restores the CPU to an active state as soon as the user resumes use of the system.

Deeper Sleep minimizes the power consumption of the CPU when it senses an extended period of inactivity by the user. Deeper Sleep is a dynamic power management mode that delivers longer battery life. Works along with Intel® QuickStart technology on Intel® Mobile Processors. By reducing power to components that are not being used, a good power management system can double or triple the lifetime of a battery. Power management is especially important for portable devices that rely on battery power. How power is efficiently directed to different components of a system. The ACPI on the System Manageability Bus enables low-power sleep mode and conserves energy when a system is idle.

DC4 - Deeper C4 Sleep: Further reduced VCCĪCPI (Advanced Configuration and Power Interface)*.

Some processors have variations of the C3 state (Deep Sleep, Deeper Sleep) that differ by how long it takes to wake the processor. The processor does not need to keep its cache coherent, but maintains other states.

C3 - Deep Sleep: Clock generator is off.

The processor maintains all software-visible state, but can take longer to wake up.

C2 - Stop Clock: Core and bus clocks are off.

Some processors also support an enhanced C1 state (C1E) for lower power consumption. The processor is not executing instructions, but can return to an executing state almost instantaneously. The CPU stays in deep C4 state longer, resulting in lower power consumption while idle. Deeper sleep comes from improvements in CPU and chipset interaction to redirect snoop cycles. C3 deep sleep and C4 deeper sleep are ACPI power management states. Power management is about improving battery life by putting the CPU to sleep when not in use. Deep sleep (C3) and deeper sleep (C4) are terms used to describe the power management of mobile platforms.
