I just turned on my Alphaserver 2100 after being

around 6 months. It will not power up at all. I have reseated
everything and tried a new PSU. Anyone got any ideas what would stop
this machine from powering up ?. The service manual just mentions the
door switch which seems ok.
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. :-)
