Windows 11 – I2C HID Device Code 12, Touchpad Stops Working After Restart (Lenovo)

Hello,

I would like to request a review from another advisor or moderator regarding this issue.

I have already shared the requested msinfo32 screenshots and system information, and confirmed that all drivers (Intel Serial IO, chipset, and touchpad) are fully up to date. However, I have not received further guidance after uploading the screenshots.

The problem still persists:

Windows 11

Lenovo laptop

I2C HID Device shows Code 12

Touchpad stops working after restart

Issue returns after every reboot

Since the issue remains unresolved, I kindly request another advisor to review and suggest advanced troubleshooting steps or escalation.

Thank you.

Hi,

Access msinfo32.exe in the search bar, take a screenshot and post it here.

Thanks

Thank you for the response. I have tried all the suggested steps, but unfortunately none of them resolved the issue. The I2C HID Device still shows Code 12 in Device Manager and the touchpad stops working after restart. Please let me know if there are any additional or advanced troubleshooting steps I can try.

The issue you are facing with the I2C HID Device showing Code 12 typically indicates a resource allocation problem. Here are some steps you can take to address this issue:

1. Check Device Manager for Conflicts: Ensure there are no other devices that are conflicting with the I2C HID Device. Sometimes, other devices may be using the same resources.
2. Update Drivers: Ensure that all drivers, especially the Intel Serial IO drivers, are updated to the latest version. You can check Lenovo's support site for the latest drivers specific to your model.
3. BIOS Update: Check if there is a BIOS update available for your Lenovo laptop. Sometimes, firmware updates can resolve resource allocation issues.
4. ACPI Settings: Ensure that the ACPI settings in the BIOS are correctly configured. Incorrect settings can lead to resource allocation problems.
5. Windows Updates: Make sure your Windows 11 is fully updated. Microsoft often releases updates that can fix bugs and improve hardware compatibility.
6. Reinstall HID Drivers: If you haven't already, try uninstalling the HID drivers completely and then reinstalling them. This can sometimes reset any misconfigurations.

As for whether this is a known Windows 11 bug, resource allocation issues can occur in various versions of Windows, and while they may not be specific bugs, they can be exacerbated by hardware and driver configurations.

Currently, there isn't a specific Microsoft-recommended workaround for this issue, but following the steps above may help resolve the problem permanently.
