This problem can have a variety of causes, you can try the following methods to troubleshoot:
1, if you use a wireless mouse, check whether the wireless transceiver and notebook contact is good, you can try to replace the USB interface test. If replacing the USB port does not work, it is recommended to replace the wireless mouse battery to avoid insufficient power. Sometimes low power mouse light will light, but the mouse will not respond.
2, take the mouse to another computer to test whether it is easy to use.
3, some brands of optical mouse may be affected by the color of the reflective surface. Some Logitech mice, for example, do not respond to a dark mousepad. So try a different contact surface (mouse pad) test.
4, USB mouse is a plug and play device, but it does not rule out that there are some older systems or due to the system's own driving reasons, resulting in normal identification of USB devices. In this case, if the mouse comes with the corresponding driver file, you can try to update the installation driver test.
5, for the USB mouse that does not provide a driver, in order to completely eliminate the problem of system driver identification, you can use the laptop touchpad to operate, go to the device manager interface of the system, view the device list, find the universal serial bus controller, and update the driver test with the device in the following list by means of the right menu \"update driver\". Alternatively, select Uninstall and rescan for hardware changes after uninstallation, so that the system automatically reloads the USB driver.
