SOLVED SIM Card not working anymore on Windows 10 with opencore bootloader

[DanyModz]

Hi, i have a lenovo thinkpad yoga x1 4 gen with dualboot: windows 10 and MacOS ventura 13.2.1 with latest version of opencore. I have only a problem on my pc: when i boot windows 10 with opencore the sim doesn’t work and it shown “off” on the settings menu and i can’t turn it on, the wi fi works without problem; if i boot windows 10 with the windows boot loader the sim works without any problems. What could cause this problem? can i fix it? Thanks in advance

Edit: if i try another bootloader for example Refind the problems with sim still occurs

As OpenCore injects the SSDTs and properties on a OS wide basis, such behavior is expected.

You have a couple of options.

- Either use Windows Boot Manager to Boot
- Use NO_ACPI fork of OpenCore

Thank you I did the second option and it works now
