So it looks like this? (not to scale, forgive the poor attempt at an ASCII diagram)

where the tabs are horrendously oversized in this diagram and you've broken 2 adjacent
tabs such as the 2 I've marked (as opposed to 2 opposite tabs in which case it'd be
easy)? Because if so, I've fixed a button that did this simply by supergluing a couple
of metal hooks in the place of the missing tabs (I find cutting pieces from a shutter
from a dead floppy disk then shaping them with a pair of very small pliers works
well). If you prepare both surfaces well the super glue is plenty strong enough and
the metal sheet from which most floppy shutters are made seems strong enough to take
being bent into a hook shape yet springy enough to hold onto the back of the
frontplate. Its also nice and thin so if you make sure the 'foot' is flat it shouldn't
raise the profile of the button noticeably if at all. Alternatively, if there is
space, a spot of epoxy may work even better (but is thicker than superglue). Having
said that, the button I was dealing with was a little bigger and I had the luxury of
being able to have a large 'foot' on the metal hook to glue onto the back of the
button. I don't know how much room there is under this button or if the space needed
to glue the metal tab in will foul up the spring ...

So your aluminium block is UNDER the port replicator's motherboard? Does that make
much difference given you've got at least 5mm of plastic and circuit board between the
bottom of the libby and the aluminium block?

No zener or other voltage clipping circuit to kill alternator spikes? How long does it
take to charge the battery on a vehicle's supply?
