Because the problem happens only on one account on one Lenovo laptop, the most likely cause is an account-specific Windows setting or device interaction on that laptop, not a bad mouse.
Try these steps in the kids account on the Lenovo:
- Check whether the mouse works at all
- Move the mouse and see whether the pointer appears.
- Press Ctrl and check whether the pointer location is highlighted.
- If the pointer never appears, test with a different USB or Bluetooth mouse.
- Rule out a hardware or connection issue on that laptop
- Unplug the mouse or wireless receiver, wait a little, then plug it back in.
- Try a different USB port.
- If using a USB hub, connect the mouse directly to the laptop.
- If the mouse is wireless, replace or recharge the batteries.
- Test the same mouse on another PC. If it fails there too, the mouse may need replacement.
- Check whether the touchscreen is interfering
- On some laptops, especially touch-enabled devices, Windows can hide the mouse pointer during touch input.
- Open Device Manager with Win + X, then expand Human Interface Devices.
- Disable HID-compliant touch screen.
- Restart the laptop and test the kids account again.
- This changes touch input behavior on the device, so re-enable it later if needed.
- Update Windows and device drivers
- Select Start.
- Type Windows Update.
- Select Check for updates and install available updates.
- If the issue continues, update the video card, mouse, and keyboard drivers from the device manufacturer.
- On laptops, also check the laptop manufacturer site for updated device-specific drivers.
- If the pointer disappears only while typing
- Windows has a Mouse Vanish accessibility feature that hides the pointer while typing and shows it again when the mouse moves.
- If the pointer comes back as soon as the mouse is moved, this behavior can be related to that feature.
If the kids account still has the issue after these steps, the problem is likely limited to settings in that Windows profile on that Lenovo laptop.
