I2C HID Driver Touchpad Failure (I think I solved it)

If the touchpad on your laptop has failed. You're playing now you see it, now you don't wit TOUCHPAD in your settings. And no customer support can assist you from HP or MSFT, try this it just worked for me...

Go to DEVICE MANAGER

Expand HUMAN INTERFACE DEVICES

And you see 12C HID Device has an error.

If you click DRIVER and then UNINSTAL DEVICE the 12C HID Device is delisted, and on startup it magically refreshes.

I was hoping that would do it, but the TOUCHPAD was still inoperative, and the error persisted.

Then, on a wild thought. I repeated UNINSTAL on all of the HID-compliant Device tabs. My thought was the whole HID Device needed a reboot. As soon as they all delisted, I said a prayer and rebooted.

And my touchpad was finally restored!

I hope this helps others, as this was really frustrating.

Ps. In Touchpad settings (once you can access them again) it's also a good idea to tic LEAVE TOUCHPAD ON WHEN MOUSE IS CONNECTED.

    I tried this tactic. Since then it's never allowed my driver to start up again. I also don't have the ability to access the power option which I originally accessed to change the option of "turn off this device to save power". I'd be wary of anyone else trying this trick as it's completely ruined my older trick of reinstalling. I'm now completely out of ideas.

    UPDATE.

    After 10 hours testing, no issues, I allowed the computer to sleep. The TRACKPAD disabled again; however, the error did not reappear in the Device Manager. Deducing the issue was related to hybernation I did a restart and again the Trackpad was functioning.

    I then discovered the true culprit.

    In about half of the HUMAN INTERFACE DEVICES elements there is an additional tab called POWER MANAGEMENT and wouldn't you know it, there's a tic box entitled, "Allow the computer to turn off this device to save power" and that, my friends, is what keeps turning off the Trackpad. Why on earth it's the default setting, God only knows.

    Hop this helps all y'all.

    This might have helped me after a couple of additional steps, so I'm replying in case this helps someone else! We'll see if my trackpad continues to work.

    I had the same issue someone else in the thread did where they didn't see the Power Management setting on the I2C HID Device or other HID Devices. I started my laptop in Safe Mode, looked at the HID Devices and saw the error was gone from the I2C Device and the properties also now showed the Power Management tab with the "turn off to save power" setting checked. I unchecked it from all of the HID devices that had the Power Management settings, restarted my laptop, and the error was gone. The Power Management tab now shows up under properties outside of Safe Mode too.

    I had been starting my laptop in Safe Mode when the trackpad would stop working, which would get it to work again on occasion (a pain with the 60 number-long bitlocker recovery key) or restarting it with the BIOS defaults, but it stopped working consistently and both were a huge hassle. So I'm really hoping this fixes it consistently!

    EDIT: It stopped working again. My laptop updated and the Power Management tab is gone from the properties during regular startup and when I'm in Safe Mode. Now a Resources tab is there, and I'm not able to change any of the settings.
