First, I apologize if I did not follow formal guidelines on posting a question/issue/problem. I am very new to posting on this forum, and I do not have the hang of it yet.
Second, I may be technically over my head on trouble-shooting these issues, as the Error: no IOReg/HDEF; BIOS/audio/disabled or ACPI problem, does not mean much to me. The ACPI problem seems like it could be anything in the ACPI script, and I don't know why it would be an issue. And the IOReg/HDEF means nothing to me. I disabled and enabled the built-in audio in the BIOS, neither worked.
Anyway, I don't expect a response to this message, as it is likely that a solution has already been posted, I am just too ignorant to realize it (no sarcasm.) I am just having a hell of a time figuring out Post #1 and how to interpret it. I will try to power through.
Sincerely,
GundamPoker
