Windows 10 has several built-in features that reduce power consumption† There’s a system-wide battery saver, power troubleshooter, USB selective suspend, and more. These features help to extend the battery life of your Windows PC†
In this tutorial, 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 becomes 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 is running on battery power, these external devices will drain your battery faster than usual. Therefore, Windows temporarily suspends inactive USB devices to conserve battery power.
For example, let’s say you have a USB fingerprint reader plugged into your computer and you haven’t used it in over an hour. Windows can suspend the device and put it in a “low power state” where it consumes very little battery power. Think of it as Windows hibernating or hibernating your USB device. If you have multiple devices connected to your PC, Windows will suspend only the inactive USB devices and ports.
USB selectively puts passive USB devices to sleep to conserve battery power. That’s all there is to the feature. Referring to this official Microsoft documentation for more information about the feature.
Problems related to USB Selective Suspend
As described above, it’s clear that selective USB suspend has huge benefits for your PC’s battery life. However, there are instances where the setting causes some USB devices to freeze or become unresponsive, especially when your PC remains inactive for too long.
Selective USB suspend is enabled by default on all Windows devices. While we recommend that you leave USB selective sleep enabled on your battery-powered computer, if you experience USB-related issues, you should disable the feature. For example, let’s say your USB drive no longer shows up in the file explorer. Or your Windows PC not detecting USB keyboard/mouse†
How to Disable USB Selective Suspend on Windows 10
Disabling selective USB suspend is an effective troubleshooting solution that can fix the mentioned USB related issues. There are always several ways to achieve this.
In the sections below, we’ll show you how to disable selective USB suspend using the Control Panel, Device Manager, or using the Command Prompt.
Disable USB Selective Suspend from Control Panel
One way to prevent your PC from temporarily suspending USB devices is to edit Windows power settings. Follow the steps below for direction.
1. Start the Windows Control Panel and set the “View on” option to Category†
2. Open the System and security menu and select Power management†
3. Select the Change subscription settings option next to your current power plan — Balanced or energy saver or High performance†
4. Select Change advanced power settings† That will open a new “Power Management” window.
5. Fold the . from USB settings section and double click Selective USB suspend setting†
If you are using a laptop or tablet, you will find two options in the USB selective sleep settings: “On battery” and “Connected”. Ideally, you would only want to enable the feature when your PC is running on battery power, as selective USB suspend is designed to conserve battery life. However, Windows gives you the freedom to disable selective USB suspend for both power options.
6. Double click on the Switched on option next to the power plan you want to customize (“On battery” or “Connected”) and select Handicapped†
7. Select Apply and then Okay to save the new USB selective suspend setting.
Please note that the USB selective sleep configuration is unique to your current/preferred power plan. If you switch plans (for example, from “Balanced” to “Power Saver”), you must repeat these steps and disable USB selective suspend for the new battery plan.
Quick Tip: You can change the USB selective suspend setting for a different power plan without going back to Control Panel. Click the drop-down button with the “Active” plan, select another power plan and expand the USB settings section and proceed to disable USB selective suspend.
From Device Manager

3. Go to the Power management and uncheck “Allow the computer to turn off this device to save power”.
4. Finally select Okay to save the setting. Repeat these steps for all relevant USB drivers on your computer.
