If the charging mouse cannot be charged, first make sure that the charging cable is properly connected and the plug is normal. Try replacing the charging cable and plug, or use a different charger for charging.
If the problem persists, it may be that the battery inside the mouse is damaged or the charging port is faulty. In this case, contact the mouse manufacturer or after-sales service center to repair or replace the battery. In addition, you can also consider buying a new rechargeable mouse instead.
