Trackpads vary in quality; some are good and others are definitely not. It’s not just about having a precision touchpad that can execute gestures. It is also about the hardware itself. Some of the laptops give preference to aesthetics of a trackpad and then end up giving users something that is impossible to use. For instance, some Lenovo laptops come with what can best be described as a shiny steel plate for a trackpad. While other laptops have something that is much better to use. However, for some users, a mouse is still better. If you’re attaching a mouse to your laptop, a wireless USB mouse is better. It will work flawlessly however it can misbehave at times. If your USB mouse has been lagging or becoming unresponsive at random this is because it is disconnecting when it shouldn’t. Here is how you can fix wireless USB mouse disconnecting and lagging in Windows 10.
If you don’t use your USB mouse for some time, Windows turns it off. To use it again, you need just a double click and Windows will enable it again. This is a basic power saving that can result in the wireless USB mouse disconnecting. There are three possible approaches to solve this issue.

USB Power Management
Windows can turn off a device that is not in use in other to save power. This is a helpful feature but at times, it can misbehave with some USB devices. It may be an issue with the device not built to work with the feature or an update may have set something off. A convenient solution is to disable power management for your USB ports.
Open Device Manager and expand the Universal Serial Bus Controllers. Double click on a USB device and in the properties window, go to the Power Management tab. Uncheck the ‘Allow the computer to turn off this device to save power’ option. After this, Your mouse should stop disconnecting every time. We should also mention that not all USB devices have a power management tab.
USB The Selective Suspending method
Your power plan can suspend a USB device to save power too. This is different from the aforementioned power management feature that you disabled in the past section. You have to set it on a per-plan basis. Right-click the battery icon in the system tray and select ‘Power Options’. Click on the current power plan and after that click ‘Advance power plan settings’. In the Advanced settings tab, simply look for ‘USB settings’. Expand this area and disable USB Selective suspend settings.
Uninstall And Reinstall Driver
If the above fails to fix the USB mouse disconnecting or lagging then what you have to do is to uninstall and reinstall the driver. Open Device Manager and locate your USB mouse device under Mice and other pointing devices. Double click on it to open its properties. In the Properties window, go to the Driver tab and click ‘Uninstall Device’. Windows will uninstall it. Just remove the dongle for your wireless USB mouse, and insert it again. Windows will automatically install the device and it should solve the issue.
Issues With The Port
There is a little possibility that this is a hardware issue. If nothing else works, then try changing the port you’ve connected the dongle to. Connect a different device to the port you had your wireless USB mouse connected with. Check if there’s an issue. You can also try connecting a USB pen drive and check whether you can transfer files or if Windows has trouble recognizing the device. If other devices are giving you a hard time, then it’s possible you have an issue with the port. This isn’t anything to worry about. It may be a very simple repair but ensure you have someone that is skilled to look at it.
