5. Troubleshooting
If you encounter issues with your ROG Harpe II Ace mouse, refer to the following common solutions:
5.1 Mouse Not Responding
- Check Connectivity: Ensure the mouse is properly connected in your chosen mode (2.4 GHz dongle, Bluetooth paired, or USB cable). Try re-plugging the dongle or cable, or re-pairing Bluetooth.
- Battery Level: The battery might be depleted. Connect the mouse via USB cable to charge it.
