Longer version elided - but very good information.

While looking for a place to buy a new one, I came across some
information, but not sure how valid it is.

If the laptop is going to be powered from AC for more than 2 or 3 days,
the battery should be removed. Leaving the battery installed in the
laptop while the laptop is powered from the AC for long periods of time
is what kills the battery.

If the laptop is going to be used for more than 2 or 3 days on AC, the
battery should be allowed to go doen to about 50 to 60% charge, then
removed and stored in a cool place

If this is true, it's certainly what is killing this one. The laptop is
my main computer so it is almost always used while connected to the mains.

Any ideas on that advice? There's more to it at

and I'll keep looking, of course, but since you appear to be so
knowledgeable, if you have any thoughts offhand I'd appreciate it.


Thanks for what you supplied already.
