If the Xiaomi wireless mouse can't be connected to the computer via Bluetooth, you can refer to the following methods to troubleshoot the issue:
1. Check whether the power switch on the bottom of the mouse has been turned to the open state;
2. Confirm whether the battery is sufficient or replace a new one. You can check it by toggling the power switch and checking the battery indicator on the mouse cover. If the battery indicator shows red, it means the battery is insufficient;
3. Make sure that your computer's Bluetooth is turned on. You can usually find this option in the system tray (Windows) or the menu bar (Mac);
4. Check if you put the mouse into Bluetooth pairing mode. There should be a blue indicator light on the mouse if it is in Bluetooth pairing mode;
5. When performing a second pairing on the same device, the old Bluetooth pairing information that has already been connected to the mouse must be deleted before the second pairing is performed;
6. Move the mouse closer to the computer and away from other wireless devices or sources of interference like Wi-Fi routers or cordless phones;
7. Try connecting the mouse to another computer to identify whether the problem lies with the mouse or the original computer;
8. Restart both your computer and the mouse, delete the old Bluetooth pairing information and then try reconnecting them.
