Modern Standby is a Windows 10 and 11 power management feature that allows devices to enter a low-power state similar to “Sleep” mode while still performing certain connectivity and background tasks such as receiving notifications, downloading updates, and syncing data. It is also known as “InstantGo” or “Connected Standby” on some devices. The PC remains in a low-power state in Modern Standby mode, allowing it to quickly wake up and perform tasks without having to fully boot up. This mode is especially useful for devices that are constantly connected to the internet, such as tablets and laptops, because it allows them to receive notifications and other updates while conserving battery life. In this post, we will describe how to disable modern standby on Windows 10 and 11.
Modern Standby mode is supported on certain hardware and requires specific hardware components such as a low-power system-on-a-chip (SoC), a network controller that supports Wake on LAN (WoL), and a solid-state drive (SSD) for storage. Often times, Modern Standby often leads to automatic BitLocker Drive Encryption as stated by Dell. Here is a guide discussing this topic “Modern Standby: Why is my PC automatically encrypted?“.
