Jittering or random movements
- Dirty sensor lens
- Crack in the sensor lens
- Polling issue (firmware issue)
- Possible tracking height (mouse pad /surface tuning — software issue)
- Bad sensor placement (hardware issue) — may be able to solve with surface tuning (Gaming only)
- Connection issue
- Interference issue
- Surface tuning issue
- Break in Sensor circuit (PCB — hardware issue)
- Dead battery
- Bad wireless connection
- Make sure the battery is fully charged. Low or dead batteries can affect mouse movement.
- Turn off your mouse or unplug the mouse from the computer and try cleaning the mouse sensor on the bottom with compressed air or a Q-tip.
- Move the mouse closer to the USB receiver (if you have a wireless mouse). If your receiver is in the back of your computer, it may help to relocate the receiver to a front port. In some cases the receiver signal gets blocked by the computer case, causing a delay.
- Keep other electrical wireless devices away from the USB receiver to avoid interferences.
- Unpair/repair or disconnect/reconnect hardware (if you have a wireless mouse).
- If you have a Unifying receiver, identified by this logo, see Unpair a mouse or keyboard from the Unifying receiver.
- If your receiver is non-Unifying, it cannot be unpaired. However, if you have a replacement receiver, you can use the Connection Utility software to perform the pairing.
- Upgrade the firmware for your device if one is available.
- Windows only — check if there are any Windows updates running in the background that may cause the delay.
- Mac only — check if there are any background updates that may cause the delay.
- Try your device on a different computer.
