Powercfg /a – this function allows the user to verify the system’s support capability
for low power. If this command identifies “Standby (S0 Low Power Idle) as a
supported power configuration, your system supports Modern Standby.
Powercfg /sleepstudy – this function provides the user with a detailed power
consumption report during sleep of all applications, drivers, and devices. This report
provides the user with indications of potentially impacting components which are
blocking the system from entering Resiliency Mode.
CONNECTED VS. DISCONNECTED STANDBY CONFIGURATION
As stated above, a common system modification to improve power consumption
during Modern Standby is to disable Connected Standby. Due to the increased
network requirements, Connected Standby will consume more power and is an initial
default method for debug and modification to allow for improvements.
UPDATE DRIVERS, APPLICATIONS, AND FIRMWARE
As detailed above, the ability for all drivers, applications, and firmware to be Modern
Standby aware is critical to the overall power optimization of a system. As such,
ensure your system has the latest verified configuration of drivers, applications and
firmware for your system. Updated drivers for your system can be found at

Summary
Modern Standby is the next evolution of the operating systems sleep state and is
meant to bridge the user experience from legacy PC devices and current mobile
devices. Modern PCs and future PCs should all exhibit similar behaviors when pushing
the power button or going idle due to inactivity.
Modern Standby will help to reduce fragmentation in the personal electronic
ecosystem, by providing the best in class battery life, responsiveness, and
capabilities while in a low-power, non-idle state.
