What is causing random mouse disconnects on Windows 10?

We investigated this particular issue by looking at various user reports and the repair strategies that are commonly being used to fix this particular problem. As it turns out, there are multiple potential culprits that are known to cause this issue:

  • Mouse hardware defect – It’s possible that you’re experiencing this issue due to a hardware defect. In this case, you should make the necessary verifications to ensure that you’re not dealing with a faulty mouse. You can do this by connecting the mouse to a different device and seeing if the random disconnects are still occurring.
  • Automatic USB Suspend is enabled for the HID device – Another potential culprit is a USB specific issue called USB suspend. If the HID device is configured to make use of Automatic USB suspend, you might experience mouse disconnects during idle periods. In this case, you should be able to resolve the issue by disabling automatic USB suspend mode via Device Manager.
  • USB Suspend is enabled for the power plan – Even if you ensured that the USB port is not permitted to use Selective suspend, your current power plan might override that setting and turn the feature back on. If this scenario is applicable, you can resolve the issue by modifying your power plan to stop using USB selective.
  • An EMI is causing the random mouse disconnects – As several users have reported, this particular issue can also occur due to constant electromagnetic interference. Based on user reports, this is commonly occurring on portable computers (laptop, ultrabooks, etc) by portable fans and coolers that are connected through USB. In this case, you should be able to resolve the issue by disconnecting the device responsible for the EMI.
  • Outdated or corrupted driver version – The random disconnects are reported in conjunction with an incomplete, outdated or incorrect mouse driver. In most case, the issue is created by Windows Update (WU) because it installs the wrong driver. If this scenario is applicable, you should be able to resolve the issue by uninstalling your current driver and installing the latest version from your manufacturer’s website.
  • Windows 10 glitch – Around June 2018, Microsoft introduced an update that is known to cause random disconnects with USB connected peripherals. Since then, MS corrected the issue by a hotfix available on all Windows 10 versions. So if this scenario is applicable, you should be able to resolve the issue by installing every pending update.
  • Power draw issue – Your PSU (Power Supply Unit) can also be responsible for these random mouse disconnects. If your USB-connected devices are drawing more power than your PSU is capable of supplying, you might encounter this issue. In this case, you should be able to solve the problem by upgrading to a better PSU or by getting a USB hub with an external power adapter.

If you’re currently trying to resolve this mouse problem on your Windows 10 computer, this article will provide you with some troubleshooting steps that should help you in resolving the issue. Down below, you’ll find a collection of methods that other users in a similar situation have successfully used to fix the random mouse disconnects.

Each of the potential fixes featured below is confirmed to be effective by at least one affected user. If you want to remain as efficient as possible, we advise you to follow the methods in the order that they are presented since they are ordered by efficiency and severity.

Let’s begin!

Method 1: Verifying if your mouse is working correctly with other devices

Before you try any of the other potential fixes present below, it’s important to make the necessary verifications to ensure that you’re not actually dealing with a faulty mouse. It’s possible that you’re USB cable/dongle is not working properly and is somehow causing the disconnections.

To cross this potential culprit from your list, simply connect the mouse to a different device and see if the issue is still occurring. If you don’t have a different computer, connect it to a smart TV or even to your Android device if you have an OTG cable.

If the disconnects are still happening, it’s clear that the issue is not isolated on Windows 10 and is not related to the mouse drivers. In this case, the only acceptable solution is to send your mouse in for repair (if you still have a valid warranty) or consider getting a new peripheral.

  3. Next, right-click on HID-compliant mouse and choose Properties from the context menu.
    Note: If you have multiple HID-compliant mouse listings, it’s because you have connected multiple peripherals of this type to your computer. In this case, repeat the instructions below with every HID-compliant mouse listing.
  4.  Inside the Properties screen of the HID-compliant mouse, select the Driver tab from the menu bar at the top and click on Uninstall Device.
  5. When prompted by the Uninstall Devices window, click on Uninstall once again to confirm the action.
  6. Once the uninstallation is complete, open your browser and search online for “*Mouse Model* + *Manufacturer* + driver. From the search results, look for the official download page. My mouse is made by Logitech, so I downloaded the latest driver version from support.logitech.com
    Note: Keep in mind that “mouse model” and “manufacturer” are simply placeholders. Replace them with the actual model and manufacturer of your mouse.
  7. After the installation executable is downloaded, open it and follow the on-screen prompts to complete the installation.
  8. When the installation is complete, restart your computer and see if your mouse is functioning normally (without random disconnects) once the next startup sequence is complete.

If the same random disconnects are still persisting even after you’ve ensured that the latest driver version is installed correctly, move down to the next method below.

Method 6: Installing any pending Windows update

As it turns out, this particular issue can also be caused by a Windows 10 glitch introduced with an update released in June 2018. Microsoft has been quiet about this problem, but there has been a surge of tickets after the update was pushed with users getting random disconnects – this glitch only seems to affect USB-connected mouse devices.

Fortunately, Microsoft patched this quietly after a couple of weeks. So if you think the issue might be caused by a glitch and you’re not up to date with the Windows updates, then installing any pending update should allow you to resolve the issue very easily.

Several affected users have reported that the random mouse disconnects stopped after they installed all Windows 10 pending updates. Here’s a quick guide on how to do this:

  1. Press Windows key + R to open up a Run dialog box. Then, type “ms-settings:windowsupdate” inside the text box and press Enter to open up the Windows Update tab of the Settings app.

  4. Start using your mouse normally and see if the issue is still occurring. If you’re still encountering random disconnects, move down to the next method below.

If the issue is still occurring even after you’ve updated your Windows 10 system to the latest build, move down to the next method below.

Method 7: Resolving the Power draw issue

As it turns out, this particular issue can also occur due to a power draw problem. If your power supply unit (PSU) is not sufficient to sustain all your USB connected devices, you might experience random mouse disconnects because your system is unable to the required power.

This is specifically reported to occur with configurations that have external hard drives connected through USB. If this scenario is applicable to your current situation, try to remove the external hard drive and see if you still get random disconnects.

If the disconnects stop and you plan on fixing the issue without losing any functionality whatsoever, you have two ways forward:

  • Get a higher PSU (power supply Unit) that is able to provide more power to your USB connected devices. Of course, this is only applicable with desktop configurations
  • Get a USB hub with an external power supply. This should be the fix if you’re encountering the issue on a laptop or ultrabook. USB hubs with included power adapters will take the load of your PSU, stopping the random disconnects.
