Hi, My System is ACPI Compatible, But after installing from Unattended installation it doesnt detect ACPI and shows it as Standard PC instead of ACPI Uniprocessor PC. I have enabled APM and when i do shutdown system will power off but when i press Power Button it doesnt shutdown or i dont see any option to select Shutdown / Hibernate / Standby when i press Poweroff button. Thanks in advnace.
