In Windows 10 and Windows 11, there are two power models for PCs:Â S3Â andÂ Modern StandbyÂ (S0 Low Power Idle). The S3 power model is an older standard and is not capable of the instant on that consumers expect from modern devices. Modern Standby is capable of leveraging all the capabilities of a modern chipset and can be integrated across the breadth of tablets and PCs today. The first iteration of Modern Standby was Connected Standby, which first shipped in Windows 8 and Windows 8.1. Modern Standby expands upon the Windows 8.x Connected Standby concept, allowing for flexibility in component selection and the ability for the OS to manage network connectivity in standby.
Windows 10 and Windows 11 Modern Standby (Modern Standby) expands the Windows 8.1 Connected Standby power model. Connected Standby, and consequently Modern Standby, enable an instant on / instant off user experience, similar to smartphone power models. Just like the phone, the S0 low power idle model enables the system to stay connected to the network while in a low power mode.
Although Modern Standby enables an instant on/off user experience like Connected Standby, Modern Standby is more inclusive than the Windows 8.1 Connected Standby power model. Modern Standby allows for market segments previously limited to the Traditional Sleep (S3) power model to take advantage of the low power idle model. Example systems include systems based on rotational media and hybrid media (for example, SSD + HDD or SSHD) and/or a NIC that doesnâ€™t support all of the prior requirements for Connected Standby.
On any Modern Standby system (whether connected or disconnected), the system remains in S0 while in standby, allowing the following scenarios to work:
On systems that are connected while in standby, wakes based on specific network patterns may also be set by the operating system to enable apps to receive the latest content such as incoming email, VoIP calls, or news articles.
This tutorial will show you how to check if the Modern Standby (S0 Low Power Idle) sleep state is supported by your Windows 10 or Windows 11 PC.
