If your laptop touchpad is causing your cursor to jump randomly, there are a few things you can try to fix it:
Clean the touchpad. Dirt and grime can build up on the touchpad and cause it to malfunction. To clean the touchpad, use a soft cloth dampened with water or isopropyl alcohol. Wipe the touchpad gently until it is clean.
Adjust the touchpad sensitivity. The touchpad sensitivity may be too high, causing the cursor to move too easily. To adjust the touchpad sensitivity, go to Settings > Devices > Touchpad. Under Sensitivity, move the slider to the left to decrease the sensitivity or to the right to increase the sensitivity.
Disable tap-to-click. Tap-to-click is a feature that allows you to click by tapping the touchpad instead of pressing a button. This feature can be useful, but it can also cause the cursor to jump randomly, especially if you accidentally tap the touchpad while typing. To disable tap-to-click, go to Settings > Devices > Touchpad. Under Taps, uncheck the box next to Tap to click.
Update the touchpad drivers. Outdated or corrupted touchpad drivers can cause a variety of problems, including cursor jumping. To update the touchpad drivers, go to the website of your laptop manufacturer and download the latest drivers for your model.
Disable the touchpad while typing. If you find that your touchpad is still causing your cursor to jump randomly, you can try disabling it while typing. To do this, open the Control Panel and go to Mouse. Click the ClickPad tab and check the box next to Disable ClickPad while typing.
Here are some additional tips:
- Avoid using the touchpad when your hands are wet or sweaty.
- Try using a different surface for your laptop.
- If you are using your laptop on a soft surface, such as a bed or a couch, the touchpad may not work properly.
- If you are using an external mouse, make sure that it is turned off or unplugged when you are not using it.
- If you are still having problems, you can contact your laptop manufacturer for support.
