Mouse curser not working

@imnoobda The basic things to test on a wireless mouse are the battery and examining the battery contacts. First remove the battery, then check the battery springs in the compartment for any rust or corrosion. If there is any corrosion, clean the contacts before replacing the battery with a new one. You can also try pairing the mouse via Bluetooth again.

Beyond that, there isn't much to repair on a mouse and it is often cheaper to replace the mouse altogether if those steps do not work.
