How to solve the broken mouse?
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
①Whether the USB interface is faulty. We can find an easy-to-use mouse and test whether it is a problem with the USB interface.
②Whether 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.
③Whether 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
①Whether the drive 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 an 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.
With the emergence of wireless multi-mode mice in recent years, the problem of wireless mouse failure has also become a thorny issue that everyone faces. Compared with wired transmission, wireless mice are divided into 2.4GHz wireless transmission mice and Bluetooth wireless transmission mice.
(1) 2.4GHz mouse
The 2.4GHz wireless mouse is not the same as the wired mouse. The main reason is that the wireless mouse needs additional power supply. If it fails, you can first check the mouse’s switch and battery to make sure it is powered and turned on. The subsequent fault judgment can refer to the wired mouse on the previous page.

(2) Bluetooth wireless mouse
① Switch and power supply. Check the switch and battery of the Bluetooth mouse to make sure it is charged and turned on.
②Check if the computer has and has the Bluetooth function turned on. Check whether there is a Bluetooth on logo in the taskbar at the bottom right of the computer desktop. If the Bluetooth function is disabled, you can change it to manual via Control Panel→Administrative Tools→Services→Bluetooth support service service agreement and start the service.
③Reinstall the driver.
