Since updating and disabling/re-enabling the driver already did not help, the next supported step is to reinstall the touchpad device so Windows can reload the driver stack.
- Open Device Manager.
- Expand Human Interface Devices and Mice and other pointing devices.
- Find the touchpad entry. On some systems it may appear as the touchpad device or as I2C HID Device.
- Right-click it and select Uninstall device.
- Restart the PC.
Expected result: Windows reinstalls the device driver after restart.
If the touchpad still freezes or stutters after reinstalling:
- Run Windows Update again, since that is the recommended method for touchpad driver updates.
- If Device Manager shows the touchpad or I2C HID Device with an error such as Code 10, uninstall that device again and restart.
- If reinstalling and updating still do not fix it, contact the Lenovo device manufacturer for model-specific help.
This approach fits the current state because the driver is already updated, and reinstalling is the documented next step when updating does not resolve touchpad problems.
