What is USB Selective Suspend on Windows 10 and How to Disable It:
Windows 10 has many Built-in features that reduce power consumption. There’s a system-wide battery saver, a power troubleshooter, USB selective suspension, and more. These features help Increase your Windows PC battery life.
In this explainer, we’ll walk you through the intricacies behind the “USB selective suspension”, what it does on your Windows computer, and how to disable the feature if it ever causes problems.
What is USB selective suspension?
Many external devices, accessories and peripherals take power from your PC when you plug in a USB port. If your computer runs on battery power, these external devices will drain your battery faster than normal. This is why Windows temporarily suspends inactive USB devices to save battery power.
Suppose, for example, a USB fingerprint reader is attached to your computer, and you have not used it for more than an hour. Windows can suspend the device and put it in a “low power state” where it consumes very little battery. Think of it as windows Hibernate or deactivate your USB device. If you have multiple devices connected to your PC, Windows will suspend only inactive USB devices and ports.
USB selectively hibernates inactive USB devices to conserve battery power. That is all in the feature. Refer to This official Microsoft document To learn more about the facility.
USB selective suspension issues
As mentioned above, it is clear that USB selective suspension has a huge advantage over the battery life of your PC. However, there are instances when some USB devices freeze or become unresponsive due to the setting – mainly when your PC is idle for too long.
USB selective suspension is enabled by default on all Windows devices. While we recommend that you leave USB selective suspension enabled on your battery-powered computer, if you are having USB-related problems, you should disable the feature. Say for example your USB drive stopped appearing in file explorer. or your Windows PC will not detect USB keyboard / mouse.
