Ah! That _is_ it! :-)
There are six solder "joints" on the top board - under the silver
stickers - three on each side. These solder "joints" connect the top
board to the ground - eg. the battery compartment metals and so
None of them are fixed, they are just two soldered connectors lying on
top of each other. If I lift the top board even a little little bit -
*wham* unit turns off. When I press it down again - *zoom* the unit
powers on again.
So, now I'm wondering how to best fix this. I am considering on just
warming all the solder points and seeing what comes out of
that. Perhaps adding a bit more soldering tin there.
Completely redoing all the solders seems tricky, as the top board is
firmly attached to the front end board and I have to bend it just to
separate these connection points. I guess I _could_ remove those huge
solders to the front board (the one where the ide-connector lies) and
then separate the top board altogether, but I fear I might do more
harm than good.
What is puzzling me is that are these solders just supposed to be
lying on top of each other or actually soldered together? It seems a
bit weird to see them just lying there, but it seems even more weird
to think that some freak accident made them all break off at the same
Anyway, I'm doing something to these things later today - so give me
good hints while you are at it :-)
