This really sounds like a classic case of the 'reset level' adjustment
("DC OK Threshhold") on the power supply being off.

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
