If the indicator light is off, it means that no signal is obtained and the Ps / 2 cable on the control box may be broken. If the light is on but still does not flash, the control box is broken, so we must replace the control box. If replacing the control box still does not work, the screen may be pressed too tightly, and the screws around it need to be loosened slightly. Because the touch screen is made of special materials, it itself is not easily damaged. If the serial port is broken or disabled, the driver cannot be installed because the serial port will be automatically searched for when the driver is installed. Even if it can be installed, the mouse will not move or cannot be positioned. It is best not to use a serial mouse to judge the quality of the serial port. The 9 serial ports may be used in different ways for them. If the screen is pressed, or the ground wire is not connected well, it will not be positioned. If some areas cannot be clicked or the response is slow, it may be affected by dust. Remove the case to remove dust.
