Hi @sunny323crom,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

Thanks for the detailed info—this can happen after Windows updates or driver conflicts, especially on touchscreen-enabled devices like your HP ENVY x360 15-ey0000. Here's how to fix the missing touchscreen functionality and the I2C HID device error:

1. Check for Hidden Devices in Device Manager

Sometimes the touchscreen driver is hidden:

• Open Device Manager
• Click View > Show hidden devices
• Expand Human Interface Devices
• Look for an HID-compliant touch screen or an I2C HID Device
  • If found with a warning icon, right-click > Uninstall device
  • Then restart your PC

2. Reinstall the I2C HID Driver

• Go to HP’s official driver page for your model: 👉 HP ENVY x360 15.6 inch 2-in-1 Laptop PC 15-ey0000 Software and Driver Downloads | HP® Support 
• Download and install:
  • Intel I/O or Serial IO drivers
  • Touchscreen or HID drivers (if listed)
• Restart your PC

3. Run HP PC Hardware Diagnostics

To check if the touchscreen hardware is still detected:

• Turn off your laptop
• Press Esc repeatedly, then F2 to enter diagnostics
• Run the Touchscreen Test (if available)

If the touchscreen test is missing, it may indicate a hardware-level issue or a firmware/BIOS problem.

4. Update BIOS and Chipset

• From the same HP driver page, install the latest:
  • BIOS update
  • Chipset drivers
• Restart and check Device Manager again

5. Reset BIOS to Default

• Restart your PC and press Esc, then F10 to enter BIOS
• Press F9 to load defaults, then F10 to save and exit

I hope this helps.

Take care, and have an amazing day!
