Check the first item - whether the computer has Bluetooth capability. The specific method is to right-click on the computer, select the Device Manager menu, and check whether there is a Bluetooth radio transmitter. If yes, it means that the computer has the function of Bluetooth, you can use a Bluetooth mouse. If there is no Bluetooth function, you need to configure a Bluetooth adapter for the computer, and then install third-party software, you can also use a Bluetooth mouse.

Check the fourth item - whether there is a block between the Bluetooth mouse and the signal receiver, if there is a metal object nearby will affect the reception of the signal, at the same time, WIFI signal and other wireless signals will also affect the signal transmission of the Bluetooth mouse. Note that the signal receiver is plugged into the USB port in front of the desktop, so that the mouse signal will be relatively unaffected.
