Hi, The proposed solution for the suggested duplicate (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1853277) is not applicable for IIL Lenovo ThinkBook submodels. I've tried the insructions there but the proposed patch cannot be applied since the string XXXX0000 is not found in the decompiled DSDT table.
Could you please indicate on how to proceed to modify the DSDT ACPI table for IIL models for the touchpad to work? Please let me know if you need further information on this.
