In Windows 10, there are two power models for PCs: S3 and Modern Standby (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 more flexibility in component selection.
Windows 10 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 up-to-date whenever a suitable network is available.
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 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.
Modern Standby systems can be connected or disconnected to Wi-Fi or a wireless local area network (WLAN) while in standby. This behavior is dictated by the hardware and/or by configuration.
Connected Modern Standby will allow you to stay connected to Wi-Fi while in standby to still receive and get notifications about email, VoIP calls, and such, but it will use more battery.
Disconnected Modern Standby will allow longer battery life, but you will no longer have the advantages of staying connected to Wi-Fi while in standby.
This tutorial will show you how to check if Modern Standby is set to be connected or disconnected to Wi-Fi while in standby in Windows 10.
