You know... this got me to thinking :)

"years ago" [was it really that long ago?] at the first shop I worked we had a
series III and a series 48 -- roughly every 3 or 6 months an HP technician
would stop by our office to perform a "PM" -- Preventative Maintenance.
(amazingly, we had very few hardware related problems with those old
beasts...)

With the advent of the "micro" 3000 [37] and the 900 series, it seems the PC
mentality of "maintenance by replacement" had taken over and I was somewhat
surprised one day to realize, "we don't have a tech coming out to do PM's
anymore" -- sure enough, in the same span of time at my last job as I was at
my first, we've had a few "hardware related" failures -- including a
choked-up power supply fan on a disk cabinet [which is why I recognized the
symptoms listed]

OTOH, the system that had the problem was never "power cycled" during the time
the drive supply went out and was replaced -- we left it running [turns out
things appeared to be "hung" waiting for the disk, so we figured, "no harm,
no foul"]  after the new supply was put into place and things fired back up,
EVERYTHING resumed right where it left off  :)
