In the ever-evolving world of technology, power management plays a crucial role in enhancing user experiences and maximizing device efficiency. One notable power model that has gained significant attention is Modern Standby. Originally based on the Windows 8.1 Connected Standby power model, Modern Standby offers a seamless user experience with its instant-on/instant-off capabilities, akin to those found in smartphones. This blog post dives into the features and benefits of Modern Standby and highlights the two operational modes: Connected Standby and Disconnected Standby.
The Power of Modern Standby
Modern Standby, an advanced power management model, provides users with an unparalleled experience of instant responsiveness and efficient power consumption. Unlike its predecessor, the Windows 8.1 Connected Standby power model, Modern Standby expands the scope of low-power idle functionality to market segments that were previously limited to the Traditional Sleep (S3) power model. By allowing the system to remain connected to the network while in a low-power mode, known as the S0 low power idle model, Modern Standby ensures real-time delivery of emails, messaging, and cloud-synced data.
Connected Standby: Always Connected for Continuous Updates
Connected Standby, the default mode of Modern Standby, offers users uninterrupted connectivity and real-time updates. With Connected Standby, the device maintains network connectivity and keeps Wi-Fi enabled, ensuring the seamless delivery of emails, messages, and other cloud-synced data. This mode allows users to experience an instant-on functionality, similar to that of a smartphone, where the device quickly resumes from a low-power state, ready for immediate interaction.
Disconnected Standby: Optimizing Battery Life
Modern Standby also introduces Disconnected Standby, an optional mode specifically designed to maximize battery life. In Disconnected Standby mode, the device continues to provide the instant-on experience, but with power-saving optimizations. By disabling Wi-Fi, Bluetooth, and other network connectivity features, Disconnected Standby conserves battery power without compromising the device's responsiveness when needed. This mode is particularly useful when users are on the move or in situations where power outlets are not readily available.
Switching Between Standby Options
To switch between Connected Standby and Disconnected Standby modes, specific commands can be executed in Windows. The following commands need to be run:
Disconnected Standby enabled:
Battery mode:
powercfg /setdcvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0
Mains mode:
powercfg /setacvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0
Connected Standby (Default) enabled:
Battery mode:
powercfg /setdcvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 1
Mains mode:
powercfg /setacvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 1
Verifying the Configuration
To confirm the applied standby mode, you can run the following command:
powercfg /a
Important Consideration
One important factor to note is that if you have set the mains mode to Connected Standby and the battery mode to Disconnected Standby, shutting down the device while it is connected to mains power will not switch it to Disconnected Standby mode. To ensure the correct standby profile is activated, it is necessary to switch to battery mode before powering off the device, simply put unplug if form the mains before you turn it off.
