Dear Brijeshwar Reddy,
Thank you for your question and for sharing the details into Microsoft Q&A Forum.
I understand how disruptive it is when the touchpad stops working, especially when Device Manager shows Code 10 on an I2C HID Device. At this point, I recommend that you review and try the steps provided in the AI generated answer on your thread. That reply typically include the most relevant checks for this scenario. To help narrow down, could you please share the details below?
- Exact Lenovo model and whether it’s Intel or AMD.
- Did the issue start after a Windows Update, BIOS update, or Lenovo Vantage update?
- In Settings > Bluetooth & devices > Touchpad, do you see the Touchpad page at all, or is it missing?
- In Device Manager > System devices, do you see any warnings on Intel(R) Serial IO I2C Host Controller (Intel), or AMD I2C Controller (AMD)?
- If you enter BIOS/UEFI, is there an option like Internal Pointing Device / Trackpad and is it enabled?
In the meantime, here are a few basic steps you can try:
- Do a full power reset
- Shut down Windows completely.
- Unplug AC power.
- Hold the power button for 15 seconds.
- Wait about 30 seconds, then power on and test the touchpad.
- Verify the touchpad isn’t disabled by hotkey or BIOS option
- Try the Lenovo hotkey that toggles touchpad (commonly Fn + F10 / Fn + F6 / Fn + F8, varies by model).
- Enter BIOS/UEFI and confirm Internal Pointing Device / Trackpad is Enabled.
- Rebuild the I2C stack
- In Device Manager:
- Under Human Interface Devices: right-click I2C HID Device > Uninstall device
- Under System devices: right-click the I2C Host Controller (Intel Serial IO I2C / AMD I2C) > Uninstall device
- Restart the PC.
- Install Lenovo-validated platform drivers
- Install (from Lenovo Vantage > System Update or Lenovo Support page for your exact model): Chipset driver, Intel Serial IO (Intel models) / relevant AMD I2C package (AMD models)
- After these installs, restart and re-check Device Manager.
- System health checks
- Open Windows Terminal (run as administrator) and run each:
sfc /scannowandDISM /Online /Cleanup-Image /RestoreHealth - Restart afterward and test again.
While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding.
I hope the guidance above helps resolve the I2C HID Code 10 issue and restores your touchpad. Wishing you a seamless Windows 11 experience and continued productivity.
