[SATLUG] HW Question - No Power

[Albert W Lochli]

I just had one where the A drive was shorting out,
power supply fan would not spin up. (and only when 
the A-drive was mounted. Free standing the PS worked.).

Let all the drives be disconnected -- the plugs
on the MoBo must be connected -- there is an
interlock requirement there.  If the power supply
fan does not spin you have isolated it to either 
the MoBo or the Power supply itself. (you may want 
to jumper the on-off switch -- rarely but sometimes
that is it.
