What Is Modern Standby?
Modern Standby, also known as S0 Lower Power Idle, is the most recent power-saving mode available on laptops and tablets. This feature is designed to give you a mobile-like feel on Windows and it is introduced in 2020. When your display device turns off, the internal components may stay on, for example, the network connection stays active to perform backend operations.
Although this instant on/off feature provides you with a faster transition between the on and off state, it also has some flaws. If you always turn on this feature, the laptop battery will run out so fast in sleep mode that it will release a lot of heat and even cause a hardware failure.
Therefore, you had better disable Modern Standby so as to improve the battery life of your PC.
How to Find Your PC’s Current Sleep State?
Before disabling Modern Standby, you need to check if your device supports this feature. Proceed with the steps below to check your current sleep mode:
Step 1. Press Win + S to evoke the search bar.
Step 2. Type cmd to locate Command Prompt and right-click on it to choose Run as administrator.
Step 3. Type powercfg /a and hit Enter.
Step 4. If you see Standby (S0 Lower Power Idle) Network Connected/Disconnected, you have enabled Modern Standby. Then, you can check Standby (S3) status. If it reports This standby state is disabled when S0 low power idle is supported, it means you can switch Modern Standby into Legacy Standby (aka S3, a more power-saving mode).
If you see that the system’s firmware doesn’t support the S3 sleep state, you can go to BIOS to see if the S3 state can be enabled in your system. After enabling it in BIOS, you can disable S0 by editing the registry.
