Hi,

Thank you for the clear explanation, that makes sense now. I also appreciate the heads-up about BIOS F.54. If I update, I will hide the TPM again in the BIOS to avoid the ACPI error.

I will reach out if I need help finding any specific drivers.

Thanks again for your help.

Hi again:

  After I updated the BIOS I didn't need to fix the ACPI Error again, I didn't have a problem, it booted right into windows no problem.

  I did check device manager for any issues with drivers that needed to be updated and I found only 1. Under "other devices" an unknown device - on Microsoft ACPI-Compliant System ?? Any idea or a driver for this to fix the yellow symbol?? Regards Heike
