Mouse failure is a common phenomenon, I believe many friends have encountered it. It's not easy to use when you are in a hurry, and it is always annoying. So why does the mouse fail? How to troubleshoot the cause after the mouse malfunctions? Let's talk about it in detail below.
There are many reasons for the failure of the mouse, such as broken mouse, poor mouse contact, system freeze, drive conflict, etc. The first two are hardware failures, and the latter two are software failures. If it is a software failure, we can restore it by setting some options in the computer system; if it is a hardware failure, it can only be replaced or sent for repair.
(1) Hardware failure
1. Whether the USB interface is faulty. We can find an easy-to-use mouse and test whether it is a problem with the USB interface.
2. Whether the mouse is damaged. Check if the optical engine of the mouse is glowing. If the engine does not emit light (except the non-visible light engine), you can plug the mouse into another computer to see if it can be recognized.
3. Whether the mouse is in poor contact. Plug and unplug the mouse repeatedly to see if the computer can recognize it. Or replace the USB interface.
If it is not a hardware failure, it is most likely a software failure. Among software failures, "drive abnormalities" accounted for the largest proportion.
(2) Software failure
Whether the driver is abnormal.. We can open "My Computer→Right Click→Manage→Device Manager→Mouse and Other Pointing Devices" one by one, and see if there is an exclamation mark in the subdirectory of "Mouse and Other Pointing Devices". An exclamation mark means that there is a problem with the driver. In the case that the mouse is not recognized, we can use the Win+R keys and enter devmgmt.msc to open the "Device Manager".
Right-click on the directory with the exclamation mark → uninstall the device. Then unplug the mouse and plug it in again, the computer will recognize the mouse again and install the corresponding driver automatically.
