No, that's not the case fortunately. It would only not start with the new
battery and the recharging circuit disabled. I soldered the old battery
back in and reconfiguring the charging circuit back to what it was. It
works fine now. It's just (1) the battery is old and I'm worried about it
leaking at some stage and (2) I'd rather have something in there that is
not rechargeable. I don't use the machine often enough for the battery to
remain charged (especially a battery as old as this one) and I have to
re-enter the CMOS parameters each time I drag it out. (:

Anyone here successfully replaced the battery?
Hi Paul,
As I mentioned, I did try a standard Lithium battery after disabling the
recharging circuit. The machine just would not fire up boot. I haven't
tried a NiMH or Lithium ion rechargeable though. I'd be interested to if these work.

Yes, I wasn't including that within my intended definition of
"successfully." :) I didn't see much in the SAMS book or in the
operations manual, except indications that the battery preserves 2K of CMOS
RAM, and that you should take it to the dealer to have the battery replaced
when it is getting low and losing track of the time (so they can back up
the CMOS RAM for you). There did not seem to be any dire warnings about
crucial parameters or firmware being lost, and there was another section
that indicated that the battery should be disconnected when taking part of
it apart, so it seems like it shouldn't have unrecoverable consequences.
But it is distressing that you're not able to get yours to start again!
I'm hoping that someone here will know a secret that we don't yet know.
