Acer Aspire A515-57 Touchpad Lags,Freezes&Jumps, is there a special elan i2c driver can be download?

I have a new Acer Aspire 5 (A515-57) on Windows 11 and the touchpad jumps, falls asleep, doesn't respond, responds too late and is generally laggy. It's practically completely unusable. Things I have tried so far:

Disable/enable touchpad via the function key.
Installed all available Windows updates
Installed the latest BIOS update
Deactivated all two/three/four-finger gestures
Played with the sensitivity level
Tap-click completely deactivated
Completely reset the touchpad settings
Primary mouse buttons swapped and reset
Cleaned the touchpad with alcohol
Uninstalled and restarted all drivers
Installed IO drivers from the support site, restarted the system
Hidden drivers also uninstalled, restarted the system
Deactivated the power saving function for the drivers
Power-saving functions generally deactivated
Switched between I2C and PS2 in the BIOS
Try not to despair

What specific options are there to solve this problem? I am not the only one who has this problem. Some users write that if you see a laptop user with a mouse, it can only be an Acer user. In any case, it is completely frustrating and time-consuming.

Is there a special elan i2c driver that can be downloaded and installed?

Don't use any type of alcohol on laptop parts, just wet wipes or plain water. You wrote "Uninstalled and restarted all drivers", what drivers and how did you restart? It is the 12C Device by Microsoft (Precision software). Make sure that 12C HID is enabled in BIOS and not PS/2, save changes on exit BIOS (F10). Uninstall in Device Manager any Elantech and Synaptics touchpad drivers in Unknow-Other Devices, Mice and other pointing devices and in Hidden Devices. Expand Human Interface Devices and if 12C HID is listed uninstall that device, do not install any drivers but just reboot and Windows will install the Microsoft Precision device. Note that when the battery is drained, and the power adapter is fast charging the performance will drop affecting the touchpad too.

Hi Puraw, thank you for your answer:

You wrote "Uninstalled and restarted all drivers", what drivers and how did you restart?

I uninstalled (German OS) - so far i remember:

HID-kompatibles Touchpad
HID-konformes Benutzersteuergerät (HID\ConvertedDevice&Col02)
HID-konformes Benutzersteuergerät (HID\VID_1EA7&PID_1006&REV_0103&MI_00&Col02)
(hidden) HID-konformes Benutzersteuergerät
HID Event Filter
Konvertiertes PDC (Portable Device Control)-Gerät
I2C HID-Gerät
USB-Eingabegerät
USB-Eingabegerät
(another hidden) USB-Eingabegerät (in the section mouse)

After a reboot, the drivers are installed again. But the not-touchable-touchpad problem still exist.

It is the 12C Device by Microsoft (Precision software).

Now I2C is enabled again, and the current I2C-Driver is:
I2C HID-Gerät
Location: Serial IO I2C Host Controller - 51E9
Provider: Microsoft
Date: 21.05.2006
Version: 10.0.22621.2506
Hardware-ID: ACPI\VEN_ELAN&DEV_0518

Is this the right driver i your point of view?

Make sure that 12C HID is enabled in BIOS and not PS/2, save changes on exit BIOS (F10).

Ok, i did this.

Uninstall in Device Manager any Elantech and Synaptics touchpad drivers in Unknow-Other Devices, Mice and other pointing devices and in Hidden Devices.

There a none Elantech and/or Synaptics driver to uninstall (except the ELAN WBF Fingerprint Sensor).
But after each try to enable/disable/uninstall/install the list of drivers is growing, there are many HID drivers with the same name but different hardware ids.

Note that when the battery is drained, and the power adapter is fast charging the performance will drop affecting the touchpad too.

Thank you for that tip, but i tried it with and without connected power adapter, and most of the time with nearly full battery.

In the Event Viewer I found three warnings “Kernel-PnP” Id 219:

* failed to load Driver\WUDFRd for the device USB\VID_04F3...
* failed to load Driver\WUDFRd for the device {DD8E82AE...
* failed to load Driver\WUDFRd for the device PCI\VEN_8086...

Microsoft writes:

The error with the driver \Driver\WudfRd failing to load is associated with the Windows User-Mode Driver Framework...

And advises:

Run the System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

I did this too, with no success.

Unfortunatly the webcam driver isnt working too. So the laptop needs an external webcam to work with zoom. There is no driver at the download section of the aspire 5. Where can i find these drivers? The internal webcam is greyed out in the device manager.
