To reduce power consumption to a minimum, the hardware powers off all devices. System power state S4, the hibernate state, is the lowest-powered sleeping state and has the longest wake-up latency.

Only system memory is retained CPU context, cache contents, and chipset context are lost.

After the wake-up event, control starts from the processorвЂ™s reset vector.

Less consumption than in state S2, processor is off and some chips on the motherboard might also be off.

System power state S3 is a sleeping state with the following characteristics:

CPU context and system cache contents are lost.

Two seconds or more, greater than or equal to the latency for S1.

After wake-up, control starts from the processorвЂ™s reset vector.

Less consumption than in state S1 and greater than in S3, processor is off, bus clocks are stopped (some buses might lose power), software resumption.

State S2 has the following characteristics: System power state S2 is similar to S1 except that the CPU context and contents of the system cache are lost because the processor loses power.

All context retained and maintained by hardware.

Less consumption than in S0 and greater than in the other sleep states, processor clock is off and bus clocks are stopped, software resumption.

System power state S1 is a sleeping state with the following characteristics: Furthermore, some devices might be able to wake the system only from S1 and not from deeper sleep states. For example, on some machines certain chips on the motherboard might lose power at S3, while on others such chips retain power until S4. Details of the intermediate sleep states can vary depending on how the manufacturer has designed the machine. All ACPI-compliant computers shut off their processor clocks at S1 and lose system hardware context at S4 (unless a hibernate file is written before shutdown), as listed in the sections below.

With each successive sleep state, S1 to S4, more of the computer is shut down. In addition, on some computers, an external indicator tells the user that the system is merely sleeping. Some devices can wake the system from a sleeping state when certain events occur, such as an incoming call to a modem.

The operating system need not be rebooted to return the computer to a working state. Unlike a system in the shutdown state (S5), however, a sleeping system retains memory state, either in the hardware or on disk. A system in one of these states is not performing any computational tasks and appears to be off. States S1, S2, S3, and S4 are the sleeping states.

powercfg -a (can be used to see what sleep states a PC supports).

Sleep is normally sleep state S3, but the BIOS can sometimes be configured to use sleep state S1 instead (used when resume from S3 does not work properly).

The CPU is powered off in sleep states S2 or greater.

There are different sleep states (S1 to S4) and the CPU state is not the same in all of them. SuperUser contributor DavidPostill has the answer for us: Is a computerвЂ™s CPU active when an operating system is in sleep mode? The Answer Is it because the CPU was actively waiting for those events to occur while in low power mode? opening the lid, pressing a button, touching the mouse), it immediately turns itself on without having to press the power button.

When you perform any action with modern computers running Windows 7, 8.1, or 10 (i.e. Would the processor still be running or active in the background in some manner or capacity and utilizing power? To the best of my knowledge, there would be no programs or processes running. Suppose you have a Windows operating system installed on your computer and you toggle the system into sleep mode before putting it away.

SuperUser reader cpx wants to know if a computerвЂ™s CPU is active when an operating system is in sleep mode:
