 ? ASSuming you're working with a deskside and not a rackmount, the door
 switch may be the problem. ?I've had 2 AS2100s fail to power on when the
 PCB in the LCD/switch panel became loose in its mounts. ?It's mounted on
 4 split pins and the PCB wears and I think the pins lose their spring,
 so when you close the door it pushes the whole board aside instead of
 closing the switch.

 ? The fix was insanely difficult and technically challenging - I jammed
 the point of a plastic toothpick into the center of each of the split
 pins and cut it off flush. ?:-)

 Dan,
 ? ? ? ?I also have an AS2100 4/275 deskside, I think. If there are useful
 tests that won't toast my machine, I can try to dig it out and run them for
 you if it'll help. Mine also hasn't been on in many moons, though, and I
 have not had a chance to get familiar with it at all. :-( .
 ? ? ? ?I assume you have access to all the documentation you want?

If you have time it would be great to know if the machine will start
up with all the boards pulled except the i/o. It would narrow down
diagnostics.
