Hi @Pecker1 

Welcome to the HP Support Community.

Thank you for posting your query.

The I2C HID Device Device cannot start" Code 10 error can be frustrating, especially when it's persistent even after various troubleshooting steps. Since you've already tried uninstalling the device, updating the driver, and even formatting your laptop, here are a few advanced steps you can try to resolve the issue on your HP Unit. Also i would reqeust you to please share me the product number.

Disable and Re-enable the Device in Device Manager

• Open Device Manager and locate the I2C HID Device under Human Interface Devices.
• Right-click on the device and select Disable. Wait a few moments, then right-click again and select Enable.
• This can refresh the device and potentially resolve driver conflicts.

Update Chipset Drivers

• The I2C HID device is linked to the system's chipset. Go to the HP support page for your specific model and download the latest chipset drivers from the Driver-Chipset section. Install and restart the PC.

Check for Windows Updates

• Open Settings > Update & Security > Windows Update.
• Ensure that your system is fully updated with the latest patches, especially those related to hardware and device drivers.

Install Intel Serial IO Driver

• The Intel Serial IO driver manages communication between the CPU and various hardware devices, including I2C devices.
• Go to the Intel website or your HP support page and download the latest Intel Serial IO driver.

Run the Hardware and Devices Troubleshooter

• Open a Command Prompt as Administrator.
• Type msdt.exe -id DeviceDiagnostic and press Enter.
• Run the troubleshooter and let it detect and fix any hardware issues.

BIOS Update

• Check the HP support page for any BIOS updates available for your specific model.
• BIOS updates often include fixes for hardware-related issues. Install any available updates and restart the laptop.

Disable Windows Fast Startup

• Sometimes, Fast Startup causes issues with I2C devices.
• Go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable.
• Uncheck Turn on fast startup and save the changes.
• Restart your laptop and see if this resolves the error.

Thanks for helping. Im not 100% surewhat the fix was. But I ran some trouble shooting program that HP had, and it updated the BIOS and other things, then I restarted the laptop and bingo , problem fixed.
