When you power it off (and then back on again), do you get the exact same 
panel indications (same lights on, same lights off) or does it seem somewhat 
random?

If the behaviour is a little different sometimes, then it could be the 
'reset level' adjustment ("DC OK Threshhold") on the power supply. 
Specifically, it could be a little low, causing the CPU to wake up before it 
should.  If this is the source of the problem, then it is something easy to 
address (and is covered in the Service Manual, ref: Section 6 - Adjustments 
and Checkout)  [The service manual is available in PDF form at
