Hello Pedro,
I’m sorry to hear that the issue persists.
Given that the touchpad is unresponsive even in the UEFI screen, it does suggest a potential hardware malfunction.
Hardware failures can sometimes occur unexpectedly due to various reasons such as component wear, electrical issues, or even manufacturing defects that may manifest over time.
It’s unfortunate that this happened just after your warranty expired.
Before proceeding with a repair quote, you might want to try System Restore.
If you have a recent system restore point, try restoring your system to a previous state when the touchpad was working.
Contacting the manufacturer for a repair quote would be the next best step. They might also offer some troubleshooting steps over the phone or online.
I hope this helps, and I wish you the best of luck in getting your touchpad fixed!
Thanks,
Ramya
