If the touchpad does not appear under HID and is not working properly, the supported fixes are to update or reinstall the touchpad driver.
- Open Device Manager.
- Look for the touchpad under:
- Human Interface Devices
- Mice and other pointing devices
- First try updating the driver:
- Use Windows Update as the recommended method.
- Or update it through Device Manager.
- If updating does not fix it, reinstall the touchpad from Device Manager.
- Reinstalling forces the latest driver to download from Windows Update.
- Restart the PC after the update or reinstall.
If the touchpad still does not appear, install the laptop manufacturer’s Chipset / Serial IO driver and then the Touchpad driver, then restart again. In similar cases, corruption of the I2C controller driver or touchpad driver can cause Windows to stop detecting the touchpad hardware.
If the problem continues after updating or reinstalling the drivers, contact the device manufacturer for hardware support.
