> > I have an IBM T40 laptop which I regularly remove
It's time for the weekly battery debate. :-)
Some people like to remove the battery from their notebook when running on
AC power, because this makes the battery last longer. Others prefer to leave
the battery in, for the protection against power failure and the convenience
of being able to unplug from AC power at any time.
I'm in the latter camp. I don't have any quarrel with the folks who like to
remove the battery, but their priorities are definitely different from mine.
I move my ThinkPad several times a day, so it would be thoroughly
impractical for me to fiddle with the battery every time. I figure the
decreased battery life costs me about $5/month. That's cheap for the
convenience it buys me.
After all, if I wanted the most economical computer, I wouldn't have a
notebook at all. I pay extra for the value a notebook brings me, and the
battery in the machine is part of that value.
