[Thinkpad] Boot problem with old A21p

[Stuart F. Biggar]

I've got an elderly A21p that worked fine until we had
a flood at our office.  It was in a docking station and
was unplugged (along with many other things) when water
started coming in.  I've left it on charge with a known
good adapter overnight with two different batteries
(both worked last month).  I've also tried starting it
in a known good docking station (works with a T43p) and
with two different adapters, and with just the battery
(two different fully charged ones).

CMOS battery measures 3.04 V when out of the machine.

Machine makes a noise (sounds like the floppy) when
the power button is pressed.  The green power light
flashes once.  Nothing else happens ...

Any hints?  The machine is long out of warranty but
was useful for running things in the lab and still has
(or at least had) a nice 1600x1200 15" display ...

Thanks

Stuart

PS - I'm in Tucson AZ - we had lots of rain and the
runoff caused streets to fill beyond capacity.  The
building has a reverse bathtub ring about 8" above
the slab :-( - across the street the building flooded
for the first time in over 75 years.  Oh what fun
dealing with "black water".  Our move from off campus
to a new building on campus is being "expedited" but
the labs aren't finished yet ...
