Maintenance

Battery Replacement

The HP M120 Wireless Mouse is powered by one AA battery, which can last up to 12 months depending on usage. When the mouse's performance degrades or it stops responding, it is likely time to replace the battery. Follow the steps in the "Installing the Battery" section to replace the AA battery.

Note: Dispose of used batteries responsibly according to local regulations.

Cleaning the Mouse

To maintain optimal performance and hygiene, clean your mouse periodically:

• Disconnect the mouse from your computer by removing the USB-A nano dongle.
• Use a soft, lint-free cloth lightly dampened with water or a mild cleaning solution (e.g., isopropyl alcohol) to wipe the exterior of the mouse.
• For the optical sensor on the underside, use a dry cotton swab or compressed air to gently remove any dust or debris. Avoid touching the sensor directly with your fingers.
• Ensure the mouse is completely dry before re-connecting it to your computer.

Troubleshooting

If you encounter issues with your HP M120 Wireless Mouse, try the following solutions:

• Mouse not responding:
  • Ensure the AA battery is correctly installed and has sufficient charge. Replace if necessary.
  • Verify that the USB-A nano dongle is securely plugged into a working USB-A port on your computer. Try a different USB port.
  • Move the mouse closer to the USB dongle to ensure it's within the 2.4 GHz wireless range.
  • Restart your computer.
• Erratic cursor movement:
  • Clean the optical sensor on the underside of the mouse.
  • Ensure you are using the mouse on a suitable surface. Avoid highly reflective or transparent surfaces. A mouse pad is recommended.
  • Adjust the DPI setting using the DPI switch button.
• Buttons not working:
  • Check for any physical obstructions around the buttons.
  • If only specific buttons are not working, it might indicate a hardware issue.
• Connection issues:
  • Remove and re-insert the USB-A nano dongle.
  • If possible, test the mouse with another computer to determine if the issue is with the mouse or the computer's USB port/drivers.
