Hi everyone,
as per title (and in signature), I encountered an issue when my laptop updates the bios: latest bios update was quite mandatory (due to a problem with embedded batteries). I'm able to downgrade it but, at reboot, bios starts again to update to the latest version (01.17) without any possibility to avoid the procedure and to stop it.
The issue: this latest bios gives me an acpi battery error and shows me no battery at all in macOS (both 11.6 and 12.0.1 RC2).
I'm not at all an expert in acpi patching so I'm here to ask you an hand. I already tried to patch it using SSDtime but with no effect.
You can find as attachments the current EFI, the acpi tables extracted with OC 0.7.2 debug, ioregistry file and some screenshots (I have a video of boot verbose, if needed).
Hope this can help to understand the issue (and to make you solve it).
Thank you so much in advance
