Just to bring closure to this (short) thread, I've solved the below 
issue.  I noticed that in addition to the 31-second beep symptom that 
the terminal was also no longer saving my settings after a power cycle 
and so I figured the back-up battery was dead (I'd replaced it when I 
got it a few years back) so I figured I'd try replacing it again and see 
if had anything to do with the prolonged beep.

Answer: Tes.  The terminal now initializes normally with a nice short 
series of beeps.  So, if anyone in the future sees similar symptoms, it 
could very well be the battery and the HP is deciding to tell you in an 
incredibly annoying and uninformative manner...
