(SOLVED) SSDT-INIT and SSDT-LED ACPI ERRORS about t480-oc HOT 1 OPEN

OK.

PART 1:
After I lot of searching, trial and error, the OINI ACPI error is no more.
I changed the SSDT-INIT

There is also a second ACPI Error:

This _TTS ACPI Error disappears only when SSDT-SLEEP is disabled in OC/ACPI.

Sleep seems to work fine without this SSDT.

Do you know what this SSDT does? Why is it necessary for this machine.
The thing is every repo in github for a t480 or a t480s includes this SSDT in its configuration. I have posted issues in this but got no answers yet.

from t480-oc.
