Acer nitro AN515-54 and having a problem with I2C hid device driver and my touchpad not working.

I have been facing an ongoing issue for the past five months with my Acer laptop. At times, the touchpad works intermittently, and the I2C HID driver in Device Manager shows no warning. Eventually, the touchpad stops working, and a yellow warning sign appears, indicating an issue. Despite trying several troubleshooting methods, including giving remote access to Microsoft support, they were unable to resolve the problem and suggested to contact Acer support. Unfortunately, I came to know that Acer does not offer free support services, which has been very disappointing. This experience has led me to reconsider purchasing another Acer laptop in the future. I would greatly appreciate any assistance or advice to resolve this issue.

Hi, intermittent touchpad failures indicate a hardware issue like a bad contact of the cable/connector, this is not an expensive repair job. You could check in BIOS if the Touchpad is set to 12C HID and not PS/2 or Basic, save changes on exit with F10 and boot to Windows. Open Device Manager-Human Interface Devices and uninstall the 12C HID device and in Mice and other pointing devices uninstall all Synaptics and Elantech drivers you may have installed. Check if you see Other Devices or Unknown Devices also in the Hidden Devices (View, Menu bar) and uninstall all those drivers as these are not for your system). Just reboot and don't install anything. If still issues go online and paste this command in the Command Prompt opened as Administrator: Dism.exe /online /cleanup-image /restorehealth and press Enter. After successful completion paste this in the Command Prompt: SFC /scannow and press Enter. This should complete with the message "….did not find any integrity violations" repeat the command till you see that.

There doesn't seem to be an option in the BIOS for changing touchpad behavior:

Although there might be something extra shown if you do a CTRL-S on that screen… There were two different touchpads used in these models though, which do you have and which driver version is installed?

If your cursor will not move or your touchpad is not working at all:

Remove connected devices - Remove all devices that are connected to the system except for the power cord. This includes external keyboard, mouse, flash drives, hard drives and other peripherals.
Enable/disable your touchpad - Many systems allow you to turn the touchpad On or Off by pressing a key combination. On most models it is FN + F7 or FN + F2, but could also be a different function key. The touchpad function key will be labeled with one of the images below.
Restart your computer - Restarting your system may help your touchpad start responding again.
Reset BIOS or UEFI to default settings - Some systems have touchpad settings in the BIOS/UEFI.
Reinstall touchpad drivers - Missing or incorrect drivers may cause your touchpad to not work properly. You can try downloading and installing the latest driver from Acer Drivers and Manuals page. You may need to attach an external mouse to complete this process.
Restore Windows- Newer versions of Windows allow you to restore your operating system without losing your personal data. Make sure you select the option to Keep my files.

If you can move your cursor but are having problems with cursor speed, erratic behavior or tapping and clicking:

Adjust touchpad sensitivity - If your cursor is moving too fast or too slow, you can try changing your touchpad sensitivity.
Disable tap to click - Accidentally making contact with the touchpad when typing can cause the cursor to jump around or leave the window.
