Here's a bit of a weird issue that perhaps someone might have experienced and
solved. If not, no harm in asking.
The machine in question was built on an EPOX 8RDA+ with AMD 2500 chip. The
board was replaced (post-warranty - kudos to Epox) due to the usual bulging
capacitor failure. To celebrate, the replacement board was put into a
Thermalrock Eclipse case in place of the old generic previous case.
Unlike the original 8RDA+ board, whenever this guy is shut down (Windows XP
Pro) it immediately restarts. I know to wait for it to shut down, and when
the case lights up a second later I just kill the power on the UPS. No harm,
but a bit irritating. I'd played at length with appropriate BIOS settings
without affecting things.
This week I unplugged the CD drive on the primary slave IDE channel, so as to
use that connection to try and help a friend whose disk drive had died due to
some sort of SMART failure. (BTW, I've failed miserably - any tricks out
there?) That channel was connected to a Lite-On CDRW unit. And I noticed
that for the several days I had the Lite-On disconnected, the unit would stay
powered down when told to power down! I reconnected the CDRW and the problem
once again recurs 100% of the time. I'd restarted the machine enough times
to be reasonably convinced that there's a cause and effect relationship here.
Obvious question: does this sort of issue ring a bell with anyone? Is there
some sort of IDE configuration widget I can diddle in the BIOS to make my
machine stay down when told to power down?
