Clark,
Do you think that if I give the terminals inside the bay a thorough clean with
abrasive, back to bare metal, that it will be safe to replace the old battery
with another.
i.e. What do you think that the chances are that the old battery was the
initiating fault? And could the whining sound I presumed was a
faulty capacitor
simply have been the battery burning off?
It's really hard to say what the original fault was without being
able to examine all the hardware. Try scraping out all the carbon
and then scrape out some plastic too, just to make sure you get
everything. After cleaning away any residue then try measuring the
contacts with with an ohmmeter, with no power connected to the
laptop. Measure it then reverse the leads and measure it again. The
higher value should be well above 100 ohms although that is largely
guess work on my part. Then try it and see.
Only very badly designed capacitors will whine, if then. Generall
whining is from inductors. Burning components typically produce more
of a hissing sound than a whine. Although the whine could be
symptomatic of an overload.
