How to Fix a Mouse Cursor That Keeps Jumping
The pointer jumps or moves unevenly during normal use.
Before you begin
Start with reversible settings checks. Keep your device supported and powered safely. Do not force connectors, open sealed batteries or try high-voltage repair steps.
How to troubleshoot the problem
- 01
Use a suitable mouse surface
Test on a plain matte mousepad rather than reflective or transparent glass.
- 02
Clean the sensor opening
Use gentle exterior cleaning per the manufacturer instructions.
- 03
Check wireless power and interference
Move the receiver close and away from crowded USB hubs or radio devices.
- 04
Adjust pointer acceleration and sensitivity
Compare behavior with pointer-enhancement settings off and a moderate speed.
- 05
Compare another device
Try the mouse on another computer or try a different mouse on the same computer.
Check the result.
Trace smooth circles in the movement tester. The trace shows browser-visible movement, not raw sensor telemetry.
