Hi @fb-10000 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thank you for trying all those steps already — I understand how frustrating it is when the touchpad remains unresponsive despite your efforts. Let’s walk through a few advanced checks to help revive the I2C HID touchpad driver on your HP laptop running Windows.

Here’s a focused approach to help you move forward:

1. Check Device Manager for Hidden or Faulty I2C HID Device

• Press Windows + X → select Device Manager
• Expand Human Interface Devices
• Look for I2C HID Device or HID-compliant touchpad
• If it’s missing:
  • Click View > Show hidden devices
  • If it appears grayed out, right-click and choose Uninstall device
  • Restart your laptop to allow Windows to reinstall it

 

2. Disable Power Management for I2C HID

Sometimes Windows disables the device to save power:

• In Device Manager, right-click I2C HID Device
• Go to Properties > Power Management
• Uncheck “Allow the computer to turn off this device to save power”
• Click OK and restart

 

3. Run HP Diagnostics

Use HP’s built-in diagnostics to test the touchpad hardware:

• Visit the HP PC Hardware Diagnostics for Windows
• Download and install the tool
• Launch it and run Component Tests > Input Devices > Touchpad Test

 

4. Update BIOS and Chipset Drivers

Outdated firmware can block I2C communication:

• Go to HP Software & Driver Downloads
• Enter your laptop’s full model number (e.g., Victus 15 FB2777AX)
• Download and install the latest BIOS and Chipset drivers
• Restart after installation

 

5. Use HP App to Check Touchpad Settings

• Open the HP App from Start menu
• Navigate to Device Settings > Input
• Check if touchpad is listed and enabled
• If not visible, this may confirm a hardware-level issue

 

6. Windows Troubleshooter

• Go to Settings > System > Troubleshoot > Other troubleshooters
• Run the Keyboard and Hardware and Devices troubleshooters

If none of these steps restore functionality, the issue may be hardware-related, especially if the I2C controller isn’t initializing. You’ve done an excellent job trying all software-level fixes. 

If you’d like help interpreting the HP diagnostics results or navigating BIOS menus, I’m here to guide you through it.
