Hi @shreea 

Welcome to the HP Support Community.

Thank you for posting your query.

The issue with the touchpad and touchscreen on your HP ENVY 13-ay1000 x360 Convertible PC (3T486AV) is likely related to a compatibility problem with the HID I2C driver or firmware after updating to Windows 11 version 25H2. Here's how you can troubleshoot and resolve this problem.

Reinstall the HID I2C Device Driver

Uninstall the HID I2C Device Driver:

• Open Device Manager.
• Right-click on the HID I2C Device with the triangle warning.
• Select Uninstall Device and check the box to delete the driver software (if prompted).

Restart Your PC:

• Restart your unit. This will allow Windows to reinstall the default driver.

Manually Install the Latest Driver https://support.hp.com/in-en/drivers 

If reinstalling the driver doesn't work:

1. Visit the HP Support website and enter your Unit's serial number or model number.
2. Check for the latest chipset and touchpad drivers compatible with Windows 11 25H2.
3. Download and install the drivers, even if they appear up-to-date.

Update I2C Controller (Chipset) Driver

Sometimes, the issue is not with the touchpad driver but with the I2C controller:

1. In Device Manager, expand the System Devices section.
2. Look for entries like Intel I2C Controller or SMBus Controller.
3. Right-click and choose Update Driver > Search Automatically for Drivers.
4. If no update is found, manually download the chipset driver from the https://support.hp.com/in-en/drivers 

Disable Windows Driver Updates

Windows updates sometimes overwrite functioning drivers with incompatible versions:

1. Open Control Panel > System and Security > System.
2. Select Advanced System Settings > Hardware tab.
3. Click Device Installation Settings and choose No to prevent automatic driver updates.

Hope this helps, Please revert if the issue persists.

Take care and have an amazing day!
