When the mouse is not working, the issue may be caused by the battery, pairing, etc. Here are some troubleshooting tips that may help you locate and resolve the problem.

If the mouse stops working and shows no response when pressing the button:

• Replace the batteries and wipe the bottom of the mouse.
• Unplug, then plug the receiver into a different USB port.
• Hold down the right-click button and the scroll wheel button simultaneously for three seconds and then release.
• Try the mouse on other devices and mouse pads.

If the scroll wheel has issues:

• Tap on the mouse and use a hairdryer to remove any dust that could be covered on the surface.
• Replace the battery.
• Plug into a different USB port.

If the cursor has lagging issues such as response delay:

1. If you connect the mouse directly, try the following steps:

• Replace the batteries and wipe the bottom of the mouse.
• Unplug, then plug the receiver into a different USB port.
• Hold down the right-click button and the scroll wheel button simultaneously for three seconds and then release.
• Try the mouse with other devices and mouse pads, if possible.

2. If you connect the mouse via a hub, try the following steps:

• Plug your wireless devices on the host port of your computer or use a USB 2.0 extension cord to move the 2.4Ghz wireless mouse away from the USB 3.0 hub.

Explanation for this issue: The USB 3.0 hub has an interference issue with the wireless device such as wireless mouse or keyboards, which may result in a dropout. This is a general issue that affects all USB 3.0 devices.
