1. Replace USB port-restart the computer;
2. Replace the mouse to test whether the mouse is faulty 1. Replace the USB interface and restart the computer test. If the fault still exists, check whether the mouse light is on. If the USB connection test has been replaced and the mouse light does not light up, it can basically be judged that the mouse is faulty;
3. If you have another computer, the easiest way is to use the replacement method to test, and connect the mouse to other machines for testing. If it doesn't work, it's a mouse fault. Note: Under normal circumstances, if the mouse light connected to the USB interface does not light up, it can basically be considered as a mouse fault.
The mouse is the external input device of the computer and the indicator of the vertical and horizontal coordinate positioning of the computer display system, so it is named because it looks like a mouse (Hong Kong and Taiwan are mice). Its standard name should be "Mouse" and its English name is "mouse". The use of the mouse is to make the operation of the computer easier and faster, rather than the tedious instructions of the keyboard. The mouse was invented by Dr. douglas engelbart of the University of California, Berkeley in 1964. At that time, douglas engelbart worked in the Stanford Research Institute (SRI) sponsored by Stanford University. Douglas Engelbart has long been thinking about how to make the operation of the computer easier, and what means to replace the tedious instructions entered by the keyboard. When applying for a patent, his name was the X-Y position indicator of the display system.
