My ph315-55 touchpad not working in windows 11

Hello Y'all,

I am near my wits end and am reaching out as a last resort. About three weeks ago my ph315-55 touchpad stopped working in windows. I have been troubleshooting this to no avail. Sometimes I can fix it, and it will work for a little and then stop (possibly related to shutdown or sleep). The touchpad works fine in bios.

Things I have attempted:

Reinstalled the touchpad and serial io drivers

Messed around in registry + every cmd troubleshooting prompt I know

Fresh windows 11 install

Reached out to Acer and Microsoft.

A few more things that I cannot remember off the top of my head

This occurred at a time when I was busy, and I did not check if a recent update caused this issue. The elan/touchpad drivers do not show up in device manager. I have a i2c HID device (code 10). Any ideas would be greatly appreciated.

I resolved the issue by re-seating the ribbon cable that connects the motherboard to the touchpad.

Just restore your system to before 3-weeks and nothing other than updates and registry edits will be lost, takes 5 minutes to restore: Type restore and click on "Create a restore point" then click on "System restore" with a date.

Thanks for the advice Puraw, I have been reading many of your comments on other similar threads. The fresh install wiped out all previous restores, but even when I restored before the same issue was occurring (possibly because I didn't have an old enough restore point). This is what I will be doing next time first, hindsight is a B. A new windows update seems to have fixed it. I just find it odd that it only wiped out my touchpad and not others.

Scratch what I said in the above post. I set a restore point earlier today when my touchpad was working. Later on, it stopped working and gave the same error after an hour of use. I ran the restore, but it did not fix the touchpad. Any other tips? I'm running current bios and windows.
