The comment made recently about memory drawing excess current if inputs
are left floating is interesting though. Proof that you do need to know
about the system you're testing as taking the modular approach to
powering up doesn't always work and might actually do more harm than

The other thing I'd add to that is to always use a dummy form of mass
storage in place of any real media, even after you're confident that the
power supply is OK - just in case on first full boot the system decides
to stomp all over the media.

Back up ROMs if possible before attempting any power up too. Oh, and
before doing anything let the system aclimatise* if it's been moved.
Moisture has a habit of getting into funny places and going unnoticed.

*or is it acclimatise? Or acclimatize for you across-the-ponders...
