Sorry for the confusion arising for this. For this particular model, only repeated beep codes indicate an error condition. One single beep will indicate that the system has passed POST tests and can continue to boot to the installed operating system.

I'm sorry that the issues experienced by denmarfl resulted in them feeling they had to return their system but I'd like to reassure you that a single beep for this system is normal and will not affect the performance of this system.

Kind regards,
John C
