If you are experiencing erratic movement when you use your mouse, it may be due to the following:

Jittering or random movements 
Likely cause: 

• Dirty sensor lens
• Crack in the sensor lens

Jumping
Likely causes: 

• Polling issue (firmware issue)
• Possible tracking height (mouse pad /surface tuning — software issue)

Drifting (in one direction, over lots of mouse movement)
Likely cause: 

• Bad sensor placement (hardware issue) — may be able to solve with surface tuning (Gaming only)

Lagging (delayed cursor after mouse movement or missing cursor movement)
 Likely causes:

• Connection issue
• Interference issue

No movement 
Likely causes:

• Surface tuning issue
• Break in Sensor circuit (PCB — hardware issue) 
• Dead battery 
• Bad wireless connection

Possible solutions

1. Make sure the battery is fully charged. Low or dead batteries can affect mouse movement.
2. 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.
3. 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. 
4. Keep other electrical wireless devices away from the USB receiver to avoid interferences.
5. 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.
6. Upgrade the firmware for your device if one is available.
7. Windows only — check if there are any Windows updates running in the background that may cause the delay.
8. Mac only — check if there are any background updates that may cause the delay.
9. Try your device on a different computer.
