I've got one of these too - beautiful computers,
wonderfully engineered.
Once the batteries start to corrode and leak, the area needs to be cleaned
AND neutralized with something acidic in order to prevent problems later
on. I have seen a number of cases where the battery leaked and the area was
cleaned up without neutralizing. Looks fine until a couple of years later
when things start getting flaky and finally die. A close look will usually
show the area where there USED to be traces! I usually use Muriatic Acid
as it does a good job of neutralizing without damaging the circuitry or the
solder joints. BTW, I only use a few drops straight muriatic acid (= 33%
HCl) and after all the foaming stops, rinse it well with water trying to
only get water on the affected area (makes drying easier). I use tap water
but DI or distilled water is best since it won't leave a residue when it
evaporates. A thorough drying follows.
Opening up the case I saw one problem the four
batteries need
replacement,
and are starting to corrode. Any idea's on
where replacements can be
found?
Always check for this. A very common problem is that the batteries corrode
and kill the motherboard.
