What should you do if a mouse becomes slower? - briefly
Replace or recharge the batteries (or verify the USB connection) and clean the optical sensor of debris; if the cursor is still lagging, reinstall or update the driver, and consider using a different mouse.
What should you do if a mouse becomes slower? - in detail
A sluggish cursor usually indicates a problem with the mouse hardware, software, or the surface it operates on. Resolve the issue by following these steps.
- Verify power source. For wireless models, replace or recharge batteries. For wired devices, ensure the cable is firmly connected and free of damage.
- Clean the sensor area. Dust or debris on an optical or laser sensor can impede tracking; use a soft brush or compressed air to remove particles.
- Inspect the mouse pad. Switch to a smooth, non‑reflective surface; avoid glossy or patterned pads that can confuse the sensor.
- Update or reinstall drivers. Download the latest driver version from the manufacturer’s website, uninstall the current driver, then install the new one.
- Adjust pointer settings. In the operating system’s control panel, reduce the pointer speed and disable acceleration to test for smoother movement.
- Test alternative ports. Move the USB connector to a different port, preferably a USB 2.0 slot, to rule out port‑related latency.
- Run a hardware diagnostic. Many manufacturers provide utilities that can check sensor performance and report errors.
- Replace the device. If none of the above actions restore normal responsiveness, the mouse hardware is likely failing and should be replaced.
Perform the steps sequentially; each action isolates a potential cause and helps restore the expected performance of the pointing device.
