What is USB Selective Suspend on Windows 10 and How to Disable It

Helps you to save battery power

Windows 10 has severalbuilt-in features that reduce power consumption. There’s a system-wide Battery Saver, a Power troubleshooter, USB selective suspend, and more. These features help to extend the battery life of your Windows PC.

In this explainer, we’ll walk you through the intricacies behind “USB selective suspend,” what it does on your Windows computer, and how to disable the feature if it ever poses a problem.

What is USB Selective Suspend?

Many external devices, accessories, and peripherals draw power from your PC when you plug them into a USB port. If your computer runs on battery power, these external devices will deplete your battery faster than usual. That’s why Windows temporarily suspends idle USB devices to conserve battery power.

Say, for example, there’s a USB fingerprint reader connected to your computer, and you haven’t used it for over an hour. Windows may suspend the device and put it in a “low power state” where it consumes very little battery power. Think of it as Windowshibernating or putting your USB device to sleep. If you have several devices connected to your PC, Windows will only suspend the idle USB devices and ports.

USB selectively hibernates passive USB devices to save battery power. That’s all there is to the feature. Refer tothis official Microsoft documentationto learn more about the feature.

Problems Associated With USB Selective Suspend

As described above, it’s clear that USB selective suspend has immense benefits on your PC’s battery life. However, there are instances when the setting causes some USB devices to freeze or become unresponsive—mainly when your PC stays idle for too long.

USB selective suspend is enabled by default on all Windows devices. While we recommend leaving USB selective suspend enabled on your battery-powered computer, you should disable the feature if you’re having USB-related troubles. Say, for instance, yourUSB drive stopped showing up in the File Explorer. Or, yourWindows PC won’t detect a USB keyboard/mouse.

How to Disable USB Selective Suspend on Windows 10

Disabling USB selective suspend is an effective troubleshooting solution that can resolve the mentioned USB-related issues. There are always several ways to get this done.

If you’re using a laptop or tablet, you’ll find two options in the USB selective suspend settings: “On Battery” and “Plugged In.” Ideally, you’d only want to enable the feature when your PC is on battery power—since USB selective suspend is designed to extend battery life.

More Troubleshooting Techniques

Are you still having problems using USB devices? Or, does your PC not disable USB selective suspend despite trying the methods mentioned above? Restart your computer and check if that changes anything. Windows may also fail to recognize a USB device that’s loosely plugged into your computer. Hence, ensure you fit the device tightly into the US port—or use another USB port.

If the issue persists, there could be a problem with your USB drivers. Open the Windows Device Manager and update your PC’s USB drivers. Conversely, rolling back the USB drivers to a previous version may also fix the problem.
