Whether gaming or work, a mouse that keeps disconnecting from the computer and then reconnecting is really annoying. It may be repetitive, or it may happen randomly. Then you might ask: Why does my mouse keep disconnecting? In fact, there are usually many reasons for the mouse to keep disconnecting from the computer, but the most common are worn USB ports, outdated drivers, system failures, USB hangs, magnetic field interference, etc. In this article, I will list 8 ways to fix the mouse keeps disconnecting from Windows 10 to help you solve the problem.

1. Restart the PC

The first method worth trying is to restart your PC. If it’s a problem with the system running or something, a reboot will fix it. Restarting closes all running programs, including programs that have errors, and returns them to their original state. If you are lucky enough, the problem is solved.

2. Check the USB ports and cables

To rule out hardware problems when checking USB ports and cables. First check the USB cables and plugs to make sure they are not physically damaged, then try the following methods.

Remove foreign bodies
Unplug the mouse’s USB cable and check for other foreign objects inside the cable and USB port. Remove any foreign objects that can cause difficult or intermittent signal transmission between the mouse and PC.

switch connection
Connect the USB cable to another USB port. If the previous USB port is worn out, it will also affect the transmission of the signal. The new USB port may solve it. Secondly, you can connect the USB interface of the mouse to other normal computers. If the connection keeps disconnecting, it is very likely that the mouse has been damaged and needs to be replaced with a new one.

3. Disable USB Selective Suspend

Some keyboards and mice remain disconnected because the USB selective suspend feature is enabled. In Windows 10, there is a USB Selective Suspend feature, which saves power by putting a device using a USB interface into hibernation after a period of inactivity. However, this feature also usually causes the mouse to require a brief wake-up time when it is restarted, and on other computers, may cause the mouse to disconnect and reconnect. To turn off USB selective suspend, follow these steps:

  1. Press the Win key, enter “Control Panel”, and click the Control Panel application that appears
  2. Open Power Options in Control Panel
  3. Click “Change plan settings”.
  4. Click “Change advanced power settings”.
  5. Find USB Settings and double click it, select USB Selective Suspend Settings
  6. Change Enable to Disable, click the “Apply” button, and then click the “OK” button to save the changes.

4. Turn off the USB Root Hub power saving option

Similar to USB Selective Suspend, the USB Root Hub power saving option is also designed to conserve computer power by closing unused USB ports while running. However, in some cases, enabling this function will cause devices such as mouse and keyboard using USB cables to continuously connect and disconnect. Disabling it may solve this problem. Follow the steps below to turn off the USB Root Hub power saving option:

  1. Press the Win key, enter “device manager”, and click the device manager application that appears
  2. Double click on Universal Serial Bus Controller
  3. Double-click USB Root Hub, click Power Management
  4. Uncheck Allow the computer to turn off this device to save power and click OK

5. Solve the problem of high power consumption

If your computer’s USB devices are using so much power that the power supply unit (PSU) cannot support all the USB devices running at the same time, it may also cause the USB mouse to repeatedly disconnect and reconnect. This usually occurs when using a USB device that requires a lot of power, such as an external solid-state drive. At this point, you can safely eject your external hard drive and unplug it to see if the disconnect remains.

6. Eliminate external environmental interference

The anti-interference ability of Bluetooth and 2.4Ghz wireless connection is not as strong as that of wired connection mode, so it is more likely to be disconnected by external interference. When there is a strong magnetic field and electronic radiation interference in the use environment, it will greatly affect the transmission quality of the wireless signal. In this environment, it is easy to cause unstable connection between the transmitting device and the receiving device. situation, causing intermittent failure to stop.

Try turning off or moving away from other household appliances, or changing the environment, it may help. Usually, the signal instability caused by external environmental interference is rare.

7. Update the mouse driver

It can also happen that the mouse keeps disconnecting when the mouse driver is buggy or out of date. Connect the mouse to another computer to test, if the mouse works fine on the other computer, then the problem should be with your computer. You can also connect a mouse that works on other computers to your computer. If the mouse does not work on your computer, it can also indicate that the problem comes from your computer. You can try updating or reinstalling the mouse driver.
