How to restore official/stock firmware? (Bad ACPI)

I installed macOS, but because of issues, I completely removed it. Now I installed Windows 10 in the full disk, and the problems are also present here. Those issues are that when it is sleeping, the power button blinks, and (just in Linux) the internal microphone doesn't work.

I believe this is related to the ACPI configuration, but I couldn't find a way to restore it the way it was on stock.

It is a Lenovo IdeaPad 330 15IKB-81DE.
